▼ The Deepwater Horizon
oil spill in the Gulf of Mexico between April and July 2010 demonstrated the importance of synoptic
oil-
spill monitoring in coastal environments via remote-sensing methods. This study focuses on terrestrial
oil-
spill detection based on hyperspectral images acquired along the coastline of the Gulf of Mexico. A number of AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) imaging spectrometer images were investigated in this research collected over Bay Jimmy and Wilkinson Bay within Barataria Bay, Louisiana, USA during September 2010.
Various remote-sensing image processing techniques were employed to detect/identify oiled vegetation. Image-derived endmembers were extracted from the atmospherically- and geometrically-corrected hyperspectral AVIRIS data via Minimum Noise Fraction transform, Pixel Purity Index generation, and n-dimensional visualization. Extracted endmembers are then used as input to endmember-mapping algorithms Spectral Information Divergence (SID) and Mixture Tuned Matched Filtering (MTMF) to yield fractional-abundance images and crisp classification images. Field based observations of the degree of
oil accumulation along the coastline were also employed, as well as in situ measurements from the literature.
Multiple Endmember Spectral Mixture Analysis (MESMA) was employed for oiled-vegetation detection and mapping in order to enable the number and types of endmembers to vary on a per-pixel basis, in contrast to simple Spectral Mixture Analysis (SMA). MESMA thus better allows accounting for spectral variability of
oil (e.g., due to varying
oil thicknesses, states of degradation, and the presence of different
oil types, etc.) and other materials, including soils and salt marsh vegetation of varying types, which may or may not be affected by the
oil spill. The classification results demonstrated that MESMA provides advantageous capabilities for mapping several oiled-vegetation classes along the Gulf of Mexico coastline, relative to the conventional approaches tested.

▼ Marine
oil spills are a serious concern to government, private, and non-governmental organizations as well as to the public at large. Chemical cleaners and bioremediation techniques can be useful in combating these disasters, but the potential synergistic effects are not well understood. In this research, the toxic effects of mixtures of a dispersant and commercial microbial solution on grass shrimp (Palaemonetes spp.) were compared by determining lethal concentrations and mortality over time. The addition of the microbial amendment significantly reduced mortality when they were exposed to an
oil/dispersant solution. Increased mixing time of both dispersant and microbial treatments prior to shrimp exposure also increased their survival. There was no significant difference in the mean 48-hour survival rate of shrimp in dispersant and microbial-amended treatments with the same mixing time. The addition of microbial solutions to dispersed
oil may produce a net positive effect on survival rates by speeding
oil spill remediation and, when feasible, can augment existing techniques.

▼ Coastal environment is extremely sensitive area. The presence of
oil and petroleum residues in the marine environment results from abusive spillages by ships and boats to the detriment of marine ecosystems navigation, and commercial actives such as fisheries, coastal industry development, and tourism; as well as to coastal resources when the
oil reaches land. Up to now, there still isnât a complete evaluation and solution for the
oil-
spill risks in Taiwan. It is very important to organize and prepare an operational response for coastal
oil pollution accidents. The use of computer models to predict the movement of
oil helps to make best use of the various measures and equipment that can be employed in case of an
oil spill accident.
In this study, the numerical model MEDSLIK is used to directly model the transport of
oil for the coast sea around Taiwan. MEDSLIK is a 3D
oil spill model designed to predict the transport, fate and weathering of an
oil spill. The MEDSLIK
oil spill model in pre-operational mode was first developed in 1997 (Lardner et al. 1998) to assist the objectives of the EU LIFE project âSubregional contingency Plan for Preparedness and response to Major Pollution Incidents in the Eastern Mediterranean-Levantineâ. The software consists of three parts, a graphical input interface through which the user enters data concerning the
spill and environmental conditions, a run module that performs the computations that simulate the
spill behaviors and a graphical output interface by means of which the user can examine the predictions of the model.
The aim of this study is to adopt MEDSLIK model to predict the expected state of the
oil when it arrives at a given location around Taiwan. The input data includes the type of
oil and its characteristics, forecasts of wind direction and strength, sea temperature, currents and conditions at sea. By using MEDSLIK
oil spill model to simulate the Tzini
oil-
spill accident, the
oil disperses between the south part of Suao Harbor and Naao. The modeling results compare well with the actual situation.
The main result is the MEDSLIK model provides the
oil-
spill movement pattern around Taiwan Sea and answers questions such as how much will evaporate, how much will be dispersed as fine droplets in the water, where the
oil spill is most likely move to, and how soon it will get there. However, the wind input data is quantitative in this study. Future tasks must fully account the impact of regional wind field to
oil movement and emphasize on anticipating likely impacts on the coast and provide an early warming and mitigation tool to plan an effective response to keep
oil away from key coastal resources.

▼ One of the most talked about subject of the present
day is ecology and environment.[1] Every year there are innumerable
seminars, workshops and conferences to discuss various aspects of
ecology and environment. If the subject of such conferences were to
create awareness of the effects of environmental pollution, they
would have performed a salutary function. But there are differences
in perception about their long-term consequences and methods of
abatement. This has lead to formation of pressure groups who try to
impose their views on their people at large without caring to view
the local situations in the true perspective. But Environment
essentially means the complete world of man and his surroundings.
Not that it was not relevant in the bygone days but its importance
has come to the focus with our increasing knowledge of science.
Today our thoughts on environment are not restricted to our
immediate surroundings alone. We are now concerned with the
environment that stretches from the depths of ocean to a few
kilometres above the earth into the stratosphere.[1] Two
fundamental elements in the exploitation of our planet s natural
resources for the benefit of mankind are water and energy.[1] Water
is available in plenty on the earth and#61630; covering as much as
two-thirds of the earth s surface and#61630; in the form of oceans,
seas, lakes, rivers, ponds, etc. According to Perkins (1977),[2]
the world s oceans cover some 71% of the earth s surface out of
which the most productive areas cover only 3% of the earth s
surface.

▼ There are limited data available on the interaction of spilt
oil and sediment commonly found on New Zealand beaches and the data available have been obtained for intermediate state east coast beaches. The west coast of New Zealand’s north island generally has higher energy dissipative to ultra-dissipative beaches.
Physical mixing of
oil with beach sediment depends on both the depth of penetration into sediment and surface elevation changes. This study assessed physical mixing depths on three contrasting beaches; a highly dissipative open coast beach, a tidally controlled beach and a sheltered estuarine beach. Estimated and measured forcing conditions were correlated with vertical maxima of disturbance. The use of spatially discrete, non-averaged measurements of the depth of disturbance allowed spatial variation to be interpreted. Surface elevation changes were evaluated in conjunction with depth of disturbance measurements which allowed morphological features to be correlated with mixing depths alongshore and crosshore. Measurement of large scale morphological change also allowed interpretation of maximum potential
oil burial depths.
Oil settling experiments were carried out to evaluate
oil settling times and behaviours.
Morphological response is a function of changing incident wave regimes, currents, pre-existing morphology and tidal range. Large-scale erosive events have been recorded and observed at Ngarunui Beach that change the bed elevation in excess of 5 m, while small bed level variation occurs on the scale of decimetres during each tidal cycle. It was found that disturbance depths varied substantially in the cross-shore and longshore during all experiments. Wave breaking was determined to be the main mechanism for sediment mixing. Hence, the significant variation across the beach is attributed to the complex morphology of the beach.
The areas most exposed to wave breaking exhibited the most disturbance at Ngarunui Beach; larger values of disturbance in the mid intertidal zone at Ngarunui Beach correspond with the zone that is most exposed to wave breaking. Cross-shore bimodal distributions of mixing were not observed. Swash processes dominated in the high intertidal zone with accretion occurring during spring tides however swash processes have limited effects on this beach, with mixing values greatly reduced under these processes. A tidally controlled beach located within the estuary close to the harbour entrance experienced significantly larger mixing depth values when no waves were present due in part to stronger currents and greater inundation during spring tides. The sheltered estuarine beach within the harbour experienced minimal mixing depths.
Values for the vertical limits of the mixing layer exceed 40 % of the breaking wave height, Hb, for reflective beaches, while on dissipative beaches, theory predicts that the values will be extremely reduced as wave energies are dispersed across wide surf zones. However, in this study, disturbance values were higher than those previously reported in the…

▼ Saltmarshes are under continuous multiple stressors such as, land loss, erosion, climate change, environmental pollutions and oil spills, which affect the ecological communities inhabiting saltmarshes. Terrestrial arthropods play an important role in the ecology of saltmarshes, affecting primary production and decomposition. Arthropods are often found in the gut contents of Seaside Sparrows and fishes making them an important trophic link to terrestrial and marine vertebrates. Insects and spiders have the potential to be a good indicator of overall marsh health and environment as they are differentially sensitive to oil exposure. Oil pollutants may have significant long-term negative impacts on the terrestrial arthropods and consequently the food web. Ten sites along the coast of Louisiana were sampled: 3 lightly-oiled, 4 heavily-oiled sites in Barataria Bay, and 3 reference unoiled sites in Delacroix, St. Bernard Parish northeast of Barataria Bay, to determine the impacts of the Deepwater Horizon oil spill on the Louisiana saltmarsh terrestrial arthropods. Insects were collected via sweep net, 20m inland from the shoreline monthly between April and June of 2013 and 2014. Orthoptera, Hemiptera, Diptera, Thysanoptera, and Araneae were the most abundant groups of arthropods found at most sites. Species richness was significantly higher (P < 0.05) in references sites than lightly-oiled and heavily-oiled in both years. Shannon Weaver Index was similar in all sites, but higher in 2014 than 2013, suggesting a positive recovery of terrestrial arthropods’ communities. Higher number of arthropods were observed in 2014 than 2013. Odonata were significantly higher in reference sites in both years. Orthoptera significantly increased in 2014 at all sites. Herbivores, Delphacidae populations increased in 2013 in response to the stress on plants due to Hurricane Isaac. Araneae were higher in oiled sites in 2013, but in 2014 the Araneae increased in reference sites, whereas they decreased in oiled sites. Overall, the terrestrial arthropods were affected by the oil and Hurricane Isaac. The oil contamination effects still persist today. Although the slow recovery of certain terrestrial arthropods was observed, long term monitoring of arthropod communities would help better understand the recovery and succession of the marsh ecosystem.

▼ The research presented in this dissertation assesses the social impacts of the 2010 BP Deepwater Horizon (BP-DH) oil spill in South Louisiana. The coastal region affected by this disaster is made up of rural communities whose residents rely on the Gulf of Mexico and its resources for their livelihoods. Understanding how this disaster has impacted the general quality of life in spill-affected communities, and how community characteristics have influenced vulnerability and resilience to negative outcomes, has important implications for basic and applied research and public policy. To examine these issues I use one-of-a-kind household survey data from the Community Oil Spill Survey (COSS) that includes a variety of measures indexing community sentiment, social vulnerability, physical health, mental health, disruptions to normal routines, economic impacts on households, and so forth. These data provide a novel opportunity to examine how the adaptive capacities of communities shape population wellness in a disaster context. This study is grounded in literatures that emphasizes the role of emplaced local community conditions for shaping ways in which people experience and interpret hazards, risks and disasters. Specifically, I assess the social vulnerability of residents of coastal communities in Southeast Louisiana which were directly affected by the BP-DH oil spill. The aim of the project is threefold: 1) to identify the nature and extent to which the oil spill impacted residents’ sentiment about their communities; 2) to investigate the variation in community level vulnerability and resilience in the wake of the disaster; and 3) to assess impacts to mental well-being tied to the loss of—or damage to—key resources upon which the victim is reliant.

oil identification techniques that are unambiguous and conclusive, even in situations where oils have been subjected to secondary environmental processes, such as, evaporation and dissolution.
The ability and functionality of the Compound Specific Isotope Correlation (CSIC) technique is tested to determine its reliability to characterize released petroleum using the carbon isotope ratios (13C/12C) of the individual gasoline-range compounds (C5-C9). In particular, this thesis studies the potential of CSIC as a robust diagnostic tool, to identify and correlate marine releases of
oil with their sources, especially those having undergone evaporative weathering.
Three crude oils (Alberta Sweet Mixed Blend, Lacula and Louisiana) added to synthetic seawater were exposed to mechanically simulated wave energy and controlled evaporative weathering at 10 °C. Time-series sampling of the gasoline-range vapour fractions from the headspace employed Solid Phase Micro Extraction (SPME). SPME-Continuous Flow-Isotope Ratio Mass Spectrometry (SPME-CF-IRMS) determined the molecular abundances and stable carbon isotope ratios (δ13C) of the gasoline-range compounds of the original and weathered oils.
Evaporation rates over the maximum 20 hour period varied for the 3 study oils. Most (74%) of the individual compounds measured in the oils display a δ13C enrichment with progressive evaporation with approximately half of the compounds in all 3 oils showing fractionation of the carbon isotopes ≤ 0.5‰ within measurement precision. The magnitude of carbon isotope shift observed in compounds pre-vs. post-weathering ranges from 0 to 2.8 ±0.6‰. There is no clear relationship identified between the degree of 13C enrichment in the oils and groupings such as chemical class, structure or carbon number. The overall weighted average 13C enrichment for all compounds in the 3 oils is approximately 1‰. Toluene was the only compound consistently exhibiting comparatively high 13C enrichment (1.6‰, 1.8‰ and 2.8‰) in all 3 oils after evaporative weathering.
Hierarchical Cluster Analysis (HCA) treatment of the CSIC data set can reliably discriminate between the 3 oils despite evaporative weathering and δ13C changes. HCA is also able to unambiguously relate the three weathered oils back to their respective original unweathered
oil.
Diagnostic shifts in δ13C of individual compounds in an
oil may potentially be used to trace weathered oils back to the source, and possibly give a estimation of time since release. However the typically rapid rate of evaporation for the gasoline-range fractions limits the time that an
oil can be successfully identified by CSIC.

▼ The aftermath of the Kalamazoo River
oil spill in 2010, which resulted in years of clean up efforts, showed that research needs to be done regarding
oil particle aggregate (OPA) formation and transport in riverine environments. While three-dimensional hydrodynamic models can track the transport of OPAs with a high degree of accuracy, in the event of an
oil spill, rapid response is necessary to protect the affected ecosystem and expedite clean-up efforts. In the rapid response model developed in this study, the river hydraulics is one-dimensional, and the formation and transport of OPAs are described stochastically via a random walk particle tracking algorithm. Application of the model to the Kalamazoo River resulted in estimations of the amount of settled
oil, and the location of the centroid of the settled
oil particles, that would be expected for different flow velocities. The main river parameter that influences the formation and subsequent settling of OPAs is the flow velocity, with higher velocities causing more OPA formation and settling rates enhancement due to greater amounts of suspended sediments. Additional work to extend to the practicality of the developed model was performed by linking the model to HEC-RAS, and the modified model was explored via an application to the Kalamazoo River.

▼ Ever since humans began using cargo by sea to transport
oil,
oil spill incidents have occurred on different scales in different environments.
Oil leaks by cargo tankers on the high seas have a bigger and more serious impact on the environment. Among the many
oil spills in the ocean, the most serious was the Exxon Valdez incident in Alaskaâs Prince William Sound (PWS). While it may not have been the largest
spill in terms of the volume of
oil leaked, its effects were far-reaching; the location of the
spill was in the sensitive area between the temperate and subtropical zones, and it was home to many fish, migratory birds, and mammals. Therefore, this location has become an important place for researchers to study the environmental and biological impacts of an
oil leak. In the past, there have been several studies conducted from various perspectives and in various stages. In 2001, the Greek
oil tanker The Amorgos ran aground near Kenting National Parkâs Long-Keng Environmental Protection Zone and seriously damaged the ecological environment. Taiwanese studies on the ecological impacts of
oil spills include investigations and evaluations done on a short-term basis, and have been mainly focused on contingency plans and designs, evaluation systems, and handling technology. Thus, the purpose of this paper is to use related studies conducted in Alaska PWS to evaluate the ecological system in the Long-Keng area and to assess the long-term impacts of an
oil spill in the ecological sensitive area of Taiwan.

▼ When a reportable oil spill occurs, stakeholders expect the responsible party to issue a release volume estimate as part of the mitigation accountability. One method of estimating a spill volume is to use environmental assessment data to enumerate the total volume of petroleum hydrocarbons detected in the environment. This method was applied to two terrestrial based pipeline spill case studies. The assessment data was used to create a conceptual site model which, along with the liquid petroleum hydrocarbon density and soil bulk density, was synthesized to estimate the spill volumes.
The case study data was collected at the time of each release for assessment, delineation, and remediation purposes. Using the data to estimate spill volumes was ancillary and complementary to its original purpose. The practical implication is that environmental assessment and remediation practitioners can readily adopt and implement this method at terrestrial based spills.

▼ Canada has become increasingly economically dependent on the exportation of bitumen to trans-oceanic international markets. As the export of Alberta bitumen from ports located in British Columbia increases,
oil spill response and readiness measures become increasingly important. Although the frequency of ship-source
oil spills has dramatically declined over the past several decades, they remain environmentally devastating when they occur. In the event of a marine
spill, great lengths of shoreline are at risk of being contaminated. Once ashore,
oil can persist for decades if shoreline hydraulic conditions are correct and remediation does not occur. Most commonly transported oils (e.g., fuel oils, Bunker C, crude
oil, etc.) have been thoroughly studied, and their fate and behaviour in the event of a marine
spill is well understood. In contrast, because diluted bitumen has been historically traded in relatively low quantities and has almost no
spill history, there is a sizable knowledge gap regarding its effects and behaviour in both the marine environment and on coastal shorelines.
The intent of this thesis was to develop a classification scheme to identify marine shorelines of high and low diluted bitumen (dilbit) retention for southeastern Vancouver Island, British Columbia. This study builds upon the outcome of former laboratory bench top dilbit and sediment research known as Bitumen Experiments (Bit_Ex). Bit_Ex investigated dilbit penetration and retention in six engineered sediment classifications ranging from coarse sand to very large pebble in accordance with the Wentworth Classification scheme. This research used Bit_Ex findings to predict dilbit retention in poorly sorted in-situ beach sediments found on shorelines representative of the southern coast of Vancouver Island, British Columbia, Canada.
Field and laboratory measurements were conducted to document the occurrence of in-situ shoreline sediments and hydraulic conditions and were used to predict dilbit retention by comparing such characteristics between Bit_Ex and unconsolidated in-situ beach sediments. Saturated hydraulic conductivity (Ks) was measured using a double-ring constant-head infiltrometer. Measured Ks values were then compared to predicted Ks values generated by five semi-empirical Ks equations. A modified version of the Hazen Approximation was selected as the most appropriate. Using measured and calculated metrics, sediments were grouped as having either low or high dilbit retention. When sediments were analysed as homogenous samples, the experimental results suggested two of ten shorelines were composed of a combination of low and high retention sections, while the remaining eight sites were of low retention. Upon the isolation of coarse surface strata, results indicated two shorelines were entirely veneered with high retention sediments, and four shorelines were a combination of high and low retention. The residual four shorelines were found to be entirely composed of low retention sediments. The results illuminate the importance…

Surveillance Program (NASP) is responsible for the monitoring of
ship based
oil pollution in Canada’s three oceans. In many of these
spills, the source of pollution is unknown as there are often no

work, the
oil spills found in 2010 on the West Coast of Canada,
alongside the collated vessel traffic data captured by the Canadian
Coast Guard are investigated to determine the vessels most likely
responsible for these spills. In terms of tools and techniques
applied,
oil spills are firstly hindcasted using the General NOAA

of their source. ArcGIS is used to geospatially reference and
combine various data sets, and lastly the Analytical Hierarchy

▼ The Deepwater Horizon
oil spill in the Gulf of Mexico between April and July 2010 demonstrated the importance of synoptic
oil-
spill monitoring in coastal environments via remote-sensing methods. This study focuses on terrestrial
oil-
spill detection based on hyperspectral images acquired along the coastline of the Gulf of Mexico. A number of AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) imaging spectrometer images were investigated in this research collected over Bay Jimmy and Wilkinson Bay within Barataria Bay, Louisiana, USA during September 2010.
Various remote-sensing image processing techniques were employed to detect/identify oiled vegetation. Image-derived endmembers were extracted from the atmospherically- and geometrically-corrected hyperspectral AVIRIS data via Minimum Noise Fraction transform, Pixel Purity Index generation, and n-dimensional visualization. Extracted endmembers are then used as input to endmember-mapping algorithms Spectral Information Divergence (SID) and Mixture Tuned Matched Filtering (MTMF) to yield fractional-abundance images and crisp classification images. Field based observations of the degree of
oil accumulation along the coastline were also employed, as well as in situ measurements from the literature.
Multiple Endmember Spectral Mixture Analysis (MESMA) was employed for oiled-vegetation detection and mapping in order to enable the number and types of endmembers to vary on a per-pixel basis, in contrast to simple Spectral Mixture Analysis (SMA). MESMA thus better allows accounting for spectral variability of
oil (e.g., due to varying
oil thicknesses, states of degradation, and the presence of different
oil types, etc.) and other materials, including soils and salt marsh vegetation of varying types, which may or may not be affected by the
oil spill. The classification results demonstrated that MESMA provides advantageous capabilities for mapping several oiled-vegetation classes along the Gulf of Mexico coastline, relative to the conventional approaches tested.

▼ ABSTRACT
This research focuses on a point-source
oil contamination scenario for surface flow created by a pipeline failure. In this hypothetical scenario, a pipeline crossing two different river types (wide and regulated, and narrow, slightly meandering) will begin to leak and contaminant the rivers. CORMIX, a U.S. EPA supported mixing zone model, was used to model concentration of the near-field, starting from the source of the contaminant and throughout the region of interest. CORMIX takes the fundamental behaviors of an
oil spill to provide an accurate and easy-to-use fate and transport model. The severity of the
oil spill is categorized into three groups based on the interaction with two water quality standards. These water quality standards are the Criteria Continuous Concentration (CCC) and the Criteria Maximum Concentration (CMC). These concentration levels are based on values that are potentially harmful to aquatic fish and plant life in the rivers.
The hypothesis is that there will be at least one trial for each river type that both the Criteria Continuous Concentration (CCC) and the Criteria Maximum Concentration (CMC) will not be met in the region of interest (16,000 meters or 10 miles). This hypothesis has been supported. When reviewing the results, seventeen of thirty-six hypothetical
oil spills were determined to be harmful to the environment. Twelve of the seventeen were classified as severe, with concentrations ending the region of interest above the CMC.

The physical component of the simulation model consists of a system of differential and algebraic equations that describe processes which influence the motions and characteristics of oil at sea. This report deals especially with the information theoretical components of the simulation model. At the beginning of this report the motivations in choosing a microcomputer for this application - instead of a mainframe - are explained. Thereupon attention is transferred from hardware to software. The reasons for selecting Fortran 77 as programming language are stated and the user-friendly elements of the model are discussed and illustrated with a few examples. The simulation software structure clearly shows that the model is divided in three major modules namely a data accumulation and processing module, an actual simulation module and an output module. All input data are summed up and the way these data are handled is discussed. The present-day required processing of input data and future input possibilities bring the survey of the data accumulation and processing module to a close. Efficient integration methods for the simulation processes are selected to improve run speed. The handling of output data and the recommended future output presentation are discussed next. Finally, simulation runs are done with test data to check is the model functions correctly. Furthermore run time, accuracy, efficiency and stability are determined and assessed. To conclude this summary the reader is kindly recommended to try out the Marine Spill Simulation Software Set.

▼ Marine oil spill dispersants containing the surfactants Tween 80, Span 80, and dioctyl sodium sulfosuccinate (DOSS) have been widely used for decades, but their environmental impact remains controversial. The interfacial science behind their formulation has been studied in this work in order to develop new, equally effective dispersants using nontoxic components. The effectiveness of dispersants containing different Tween 80-Span 80-DOSS (T-S-D) blends was measured using a Stirred Flask Test and correlated with the dynamic oil-water interfacial tension (IFT) produced by each dispersant (Chapter 3). Very low IFT (<10-4 mN/m) was produced by both DOSS-rich dispersants and Span 80-rich dispersants, but DOSS-rich dispersants were significantly more effective and adsorbed to the oil-water interface faster than Span 80-rich dispersants. In order to investigate whether T-S-D dispersants form water-in-oil microstructures which influence dispersants’ interfacial adsorption rates, T-S-D blends were added to a transparent, low-viscosity model crude oil and studied using cryo-transmission electron microscopy and dynamic light scattering (Chapter 4). T-S-D blends formed spherical water-in-oil microstructures in the oil, and the microstructures formed by DOSS-rich T-S-D blends were much smaller than those formed by Span 80-rich T-S-D blends. This may explain why DOSS-rich T-S-D blends adsorb to the interface faster, and thus are more effective, than Span 80-rich T-S-D blends. Blends of Tween 80 and lecithin (L), a biosurfactant which also forms water-in-oil microstructures, were investigated as a substitute for T-S-D dispersants (Chapter 5). The most effective L-T dispersants performed comparably to the most effective T-S-D dispersants in the Baffled Flask dispersant effectiveness test. However, lecithin-rich L-T dispersants were significantly more effective than Tween 80-rich L-T dispersants which produced lower or comparable IFT, even though interfacial adsorption rates of L-T dispersants did not vary as a function of lecithin:Tween 80 ratio. This suggests that interfacial phenomena other than dynamic IFT influence L-T dispersants’ effectiveness. The interface between seawater and crude oil treated with L-T dispersants was therefore studied using light microscopy, cryogenic scanning electron microscopy, and droplet coalescence tests (Chapter 6). Tween 80-rich L-T dispersants caused oil-into-water spontaneous emulsification, indicating rapid dispersant leaching from oil into water. This may explain why Tween 80-rich L-T dispersants are less effective than lecithin-rich L-T dispersants which produce similar IFTs. Conversely, lecithin-rich L-T dispersants exhibited water-into-oil emulsification, indicating that such surfactant blends are stable in the oil and perhaps explaining why some lecithin-rich L-T dispersants are as effective as T-S-D dispersants which produce much lower IFT. Possible mechanisms for the spontaneous emulsification induced by L-T dispersants are discussed, based on images of the spontaneously emulsifying L-T…

▼ Polycyclic aromatic hydrocarbons (PAHs) are a common contaminant in wetland soils. They are a group of compounds widely distributed in the environment and tend to accumulate in soils. Major contribution to removal of PAHs is biological degradation. For investigating the biodegradation potential of PAHs influenced by tidal actions, equipment was built for simulating the tidal actions, and concentrations of phenanthrene, pyrene, and benzo[e]pyrene were added to the soils samples which were collected from wetland. Experiments were then conducted over 120 days. Redox potentials and PAHs concentrations were measured and analyzed. Results are concluded: 1) influenced by tidal action, phenanthrene, pyrene, benzo[e]pyrene were rapidly biodegraded during the first 40 days followed by slow but continuous biodegradation in the next 80 days, 2) tidal action enhanced approximately 15.2%, 13.9%, 12.2% of the removal efficiencies of phenanthrene, pyrene, and benzo[e]pyrene in first 37 days, 3) redox potential can change rapidly and significantly in coastal wetland soils in response of flooding and draining, 4) redox potentials in submerged soils and periodically emerged soils were significantly different, which is 70 mV higher in the periodically emerged one.

▼ Many of the organic components of oil have the capacity to persist in the environment, bioaccumulate in tissues, and are toxic to surrounding organisms. Since the early 1970s, environmental assessment programs have utilized bivalves as monitoring tools of chemical contaminants in the marine environment. Because of their sedentary and filter-feeding habit (bioaccumulation), mussels and oysters been employed as sentinel organisms in environmental quality monitoring studies in coastal ecosystems. The use of indigenous (diploid) bivalves for biomonitoring water quality is limited during the summer months due to high stress and changes in biochemical composition induced by reproductive development. In this work caged diploid and triploid oysters were compared to one another to determine if seasonal variations in total polycyclic aromatic hydrocarbon (PAH) bioaccumulation exist between the ploidy. Variations in bioaccumulation between the two ploidy were tested using a static laboratory exposure study and a real-time field monitoring (15 months) study in Barataria Bay, Louisiana. A modified QuEChERS and dispersive solid phase extraction (dSPE) method were developed and validated for determination of PAHs in oyster tissue. Laboratory oil exposure results showed there was a significant increase of 40.0%, 45.3%, and 48.9% in total PAH content between the summer diploid and triploid oysters with the 500, 5000, and 25000 ppm exposure treatments, respectively. There was a 31.3% to 58.2% increase in total PAH content between the summer diploid oysters and remaining seasonal treatments (winter diploid and triploid) over the exposed oil treatment range (500, 5000, and 25000 ppm). Significant increases (17.2% to 33.4%) in total PAH content within the triploid oysters were observed at the Bay Jimmy field sites for the months coinciding with the spawning season (June-September) and elevated lipids levels in the diploid oysters. In contrast, triploid oysters only displayed a 4.81% to 5.43% increase in PAH content within their tissue during the winter and early spring months (November-early May). The use of triploid oysters as a biomonitoring tool is feasible for assessing environmental impacts following chemical or oil spills. A caged triploid oyster monitoring system is a viable alternative to indigenous diploid bivalves throughout the year.

▼ During the DWH oil spill, vast quantities of crude oil were released into the sea-surface environment of the Gulf of Mexico. There has been ample research focused on the transport of oil into the different environmental sections. Evaporation has been considered to be the only transport pathway of oil spill matter into the atmosphere. However, the aerosolization of oil and dispersant via bursting bubbles as they occur in whitecaps and breaking waves has not been considered in the oil and dispersant budget calculation. This transport vector is significant as it is the dominant source of particulate matter production in the atmosphere. In our work, the possibility of the ejection of dispersant components in the atmosphere through adsorption on the surface of bursting bubbles was studied and quantified for the first time in a laboratory scale bubble column reactor and by molecular dynamic simulation. Although the presence of Corexit components in water and sediment has been documented, there has been no investigation on the atmospheric transport of surfactant content of Corexit. In addition to characterizing dispersant components in the air, their neglected impact on enhancing the emission rate of oil matter into the air was studied and quantified. We showed that in spite of the primary aim for dispersant use which is facilitating the dispersion of oil into the water column, in the presence of breaking waves and bursting bubbles the aerosolization of intermediate/ semi/ non-volatile oil components into the air will be enhanced. Different experiments on pure alkanes, oil, and premixed oil with Corexits/surfactants were conducted in the bubble column reactor to study and quantify the effect of bursting bubbles on the transport of oil/dispersant components into the air. Once the oil/dispersant/surfactant materials are adsorbed at the air-water interface, they are ejected by bursting bubbles into the atmosphere. The concentration and subsequent ejection rates of oil and dispersant components were measured by sampling the effluent of the reactor in the air and compared through different experiments. Our results show the aerosolization by bursting bubbles is of particular importance for the fate of SVOC (semi-volatile organic compounds) such as alkanes with more than eighteen carbon atoms, as dissolution and evaporation are negligible for these compounds. Scanning electron microscope coupled with energy dispersive X-ray images identifies the carbon fraction originated from oil/dispersant compounds associated with salt particles of aerosols. The application of both Corexit 9500 and Corexit 9527 facilitates aerosolization by enhancing the dispersion of the oil in the water column and improving the flotation capacity of the bubbles. Also, mechanistic experiments of a bursting bubble, observed with a high speed camera, clearly show enhancement in droplet production when we add dispersant to oil. The possibility of the emergence of surfactant components of Corexit in aerosol samples was investigated and quantified for the first…

▼ Abstract The aim of this study was to determine the impacts of the Deepwater Horizon (DWH) oil spill on the common reed Phragmites australis, and the processes controlling species effects and recovery, via a greenhouse mesocosm study. In the greenhouse DWH source oil, weathered approximately 40% by weight and emulsified, was applied to the aboveground shoots of P. australis growing in marsh sods to produce the following treatment-levels: (1) oil coverage of the lower 30% of shoot-height, (2) the lower 70% of shoot-height, (3) repeated oil coverage of the lower 70% of shoot-height, (4) 100% oil coverage of shoots, (5) oil applied to the soil at a rate of 8 L m⁻², and (6) unoiled controls. I quantified a strong resilience of P. australis when oil was applied only to aboveground biomass, with negative impacts becoming apparent when oil was added to the soil profile. The Total biomass and stem cumulative length were both impacted by the addition of 8 L m⁻² of weathered DWH source oil to the soil profile. Due to the apparent negative results of adding oil directly to the soil, a second experiment was designed to better understand impacts from soil oiling. Aboveground biomass was harvested from the sods that had received only shoot oiling and allowed to regrow for two months, at which point weathered DWH source oil was applied to the marsh sods at rates of (1) 0 L m⁻² (control), (2) 4 L m⁻², (3) 8 L m⁻², (4) 12 L m⁻², and (5) 16 L m⁻². This experiment verified that increased oiling to the soil profile increased negative impacts to P. australis, reducing stem cumulative length, aboveground biomass, and belowground biomass at the highest oiling rates. Higher oiling doses resulted in higher rates of soil respiration and reduced soil Eh. Based on my research, complete mortality of P. australis is unlikely from exposure to weathered and emulsified DWH source oil. However, vertical growth, above and belowground biomass, and other plant processes will be impacted, with oiling to the soil having much greater impact than oiling to the aboveground shoots.

▼ Inherently resilient practices are one mechanism that communities engage in to cope with disruptive events. A community retains and passes down the practices associated with inherent resilience in their collective memory. The inherent resilience of a community is developed over time, yet the explanation provided by Colten et al. lacks a genesis of how this process developed particularly in relation to the oil industry’s entry into Louisiana. The foundations of these practices will be explored through historic court documents to find encounters between oystermen and oil spills. In addition to legal resources, I also investigate newspaper articles and other historic sources to trace legal responses and public perceptions. Through these documents, I link the responses to oil spills that occurred in the 1970s studied by Colten and others with the events that occurred in the 1930s with new economic force of the oil industry. By identifying the emergence of the inherent resilience practices, this work will reveal how social groups cope with new hazards. The initial response will help researchers further understand how cultures have adapted overtime to hazards. The processes employed at the local level in response to a hazard event are critical in understanding and developing policy to mitigate future hazards.

▼ Crude oil from Deepwater Horizon Macondo oil spill is currently present in Louisiana coastal surface sediments and its effects on the coastal ecosystem are still being realized. Deposition of 2- and 3-ring PAHs (alkylated naphthalenes and phenanthrenes) on the exterior of Spartina alterniflora and Avicennia germinans leaves have been demonstrated in marshes impacted by Macondo spill. Whether these deposition events result from contaminated tidal water or volatilization followed by deposition onto the leaf surface has not been conclusively established. Measurements of PAH deposition on the leaf surface of black mangrove (Avicennia germinans) can provide important evidence of the mechanism of deposition since these plants are rarely submerged by tidal water. Study objectives were to quantify and observe the uptake mechanisms of PAH accumulation as a function of time, leaf age, and leaf fraction in mangrove leaves from a heavily oiled site at Bay Jimmy marsh in Barataria Basin, LA. PAHs did not accumulate over time or leaf age indicating diffusion and equilibrium processes dominated and occurred quickly. PAHs accumulated in the inner tissue of the leaf posing a potential for long-term internal cycling of PAHs in a sediment-vegetation-biota system. Semipermeable membrane devices (SPMDs) were utilized in air and marsh surface in the field as a simple analogue to investigate the transfer process. Higher correlations between leaves and SPMDs were observed for C1-naphthalenes than the other PAHs studied. The plant – air partitioning coefficient (KPA) for various PAHs in field contaminated mangrove leaves was quantified using an experimental partitioning apparatus and compared to respective KPA values calculated for Spartina alterniflora. All KPA coefficients were well below 8 which supports the dominant uptake process of air phase PAHs is equilibrium partitioning between the vegetation and the gas phase.

▼ How do many species live in a certain place? How does species composition changes among habitats? And what mechanisms decide species distribution? These are fundamental questions in community ecology. I first investigated ant diversity in two coastal ecosystems (dunes and wetlands) in the northern Gulf of Mexico, and then used the distribution patterns to infer assembly processes that structure ant communities in coastal areas. Specifically, the following hypotheses are tested: (1) coastal systems support lower ant diversity due to the unsuitable environment; (2) species living near the seashore are a subset of those exist near inland; (3) deterministic processes are the dominant forces driving coastal ant communities. Forty-six and 22 ant species were found in dunes and wetlands, respectively. Although some ants were associated with certain habitats, no species could be considered a coastal specialist. Clementsian was the best model describing how ants change along environmental gradient in dunes. This indicated that each habitat supported a unique ant assemblage. In wetlands, most ants living in marshes could also be found in swamps, which is consistent with the nested pattern. Abiotic factors were the dominant forces that decide ant diversity and community structure. For example, wetlands are flooded most of the year, which eliminates the species nesting in the soil. In addition, the physical habitat structure of wetlands and dunes is simple because of the lower plant diversity. Niches are limited for ants to nest in and forage. Biotic factors, such as the influence of vegetation and species interactions, were weak because few mosaic patterns, pairwise co-occurrence, and correlation between ants and plants was detected in this study. The contribution of stochastic processes increased under the relatively benign environment (under bushes). In addition, this research suggested that ants can be used as biological indicators in coastal dunes and wetlands. Fragmentation, habitat restoration, oil pollution, and invasive species all influenced ant diversity and community structure. Although the responses of ant assemblages to disturbances were situation-dependent, the common effect was the invasion of the red imported fire ant, Solenopsis invicta Buren, following disturbances.

▼ The Deepwater Horizon
oil spill occurred in 2010,
oil and dispersants were spread across the surface and the deep-sea. Meiofauna community biomass increased regardless of whether the station had signatures of the
oil spill or not. Increases in meiofauna biomass possibly indicate a bentho-pelagic coupling of surface waters and benthic communities. The increase in biomass was mainly due to nematode abundance increases and not individual biomass size. In the years following the
oil spill, meiofauna community biomass remained elevated compared to pre-
spill conditions. Biomass decreased in the years following returning closer to pre-
spill values, possibly indicating signs of recovery in the meiofauna community.

▼ Biodegradability studies were conducted in order to
investigate the effects of chemical dispersion on petroleum
biodegradation. Indigenous microorganisms are capable of degrading
hydrocarbons, but the role dispersants play in the biodegradation
process is inconclusive based on current knowledge. The recent
Deepwater Horizon
oil (DWH) blowout has raised questions not only
about the biodegradability of the
oil in deep waters and surface
waters of the Gulf of Mexico (GOM) but also about the rate of
biodegradation of the dispersants per se and the dispersed
oil.
Corexit 9500 (C9500) and JD-2000, both listed on the National
Contingency Plan Product Schedule, were used to disperse petroleum.
Since the temperatures of the GOM at depth and at the surface are
substantially different, we aimed to determine biodegradation rates
at two temperatures typical at those locations: 5 °C, corresponding
to average temperature at depths > 1000 m, and 25 °C,
corresponding to the average temperature in the top 5 m. The
cultures, termed cryo and meso, were isolated from the deep sea and
top 5 m of the GOM, respectively. Subsequently, both cultures were
enriched at corresponding temperatures. The method of preparing
dispersed
oil was based on the Baffled Flask Test used for testing
dispersant effectiveness. The comparative study of the
biodegradation of South Louisiana crude
oil with and without the
presence of JD-2000 showed that different dispersants can affect
oil biodegradation through different mechanisms. C9500 enhanced the
biodegradation of alkanes by promoting the adherence of
microorganisms to
oil droplets. JD-2000 improved the dissolution
rate of soluble aromatic compounds and subsequently increased their
rates of biodegradation in the aqueous phase. The light to medium
weight
oil, Alaska North Slope crude
oil (ANS), used in the first
part of this study and the dispersant, C9500, were set at two
different initial concentrations of
oil and dispersant with the
dispersant-to-
oil ratio being constant. The results indicated that
C9500 had certain positive effect on the biodegradation of ANS,
both in the high (1,000 ppm by volume) and low (40 ppm by volume)
oil loading experiments. In the low concentration experiment, the
percentage of alkanes persisting was higher than in the high
concentration experiment, whereas the extent of biodegradation of
some of the less soluble aromatics increased under low
oil
concentration conditions. The presence of C9500 shortened the lag
phase of aromatics biodegradation in the low concentration
experiments by 4 d (from 16 d to 12 d).The last part of the study
was designed to determine the rate of biodegradation of two
different petroleum oils, fresh ANS and a heavier, viscous refined
product, Intermediate Fuel
Oil 120 (IFO120) with and without the
presence of the two dispersants. The enhancement of
oil
biodegradation by chemical dispersion was greater in the
experiments with ANS than in the ones run with IFO-120, probably
because of the different chemical composition and physical
properties of two oils.…

▼ Accidental
oil spills into oceans account for a large
part of the total
oil discharged in the environment. If prompt
responses are not instigated, the spilled
oil will spread on the
water surface and possibly reach the shorelines, and adversely
affect the marine and coastal environment as well as the biota.The
use of chemical dispersants is one of the common
oil spill cleanup
techniques. Dispersants break down the large
oil slicks into small
droplets and thus mitigate the harmful effects of
oil slicks on the
shorelines, birds, and mammals. Despite their advantages like
speedy treatment of large
spill areas, applicability in harsh
weather conditions, and possible promotion of biodegradation,
concerns about dispersants effectiveness and toxicity as well as
long-term environmental impacts limit their application. In the
aftermath of the Gulf of Mexico
oil spill, responders delivered
Corexit dispersants (mostly Corexit 9500, C9500) to the sea surface
and the wellhead in unprecedented amounts (1.84 million gallons).
Although the toxicity studies by the U.S Environmental Protection
Agency have demonstrated very low acute toxicity of C9500, long
term environmental effects of the dispersants and the dispersed
oil
are still unknown. The biodegradation of dispersed
oil has been
intensively investigated, but only a limited number of studies
provided systematic and quantified analyses. Besides, there is a
lack of information about the fate of dispersant itself. To answer
these questions, this study evaluated the biodegradation of Alaska
North Slope
Oil (ANS), dispersed ANS and dispersant itself by
estimating first-order decay rate coefficients of the
oil
components, as well as the surfactants included in the dispersants.
Two types of dispersant products, C9500 and JD-2000, were tested to
determine their effects on
oil biodegradation and to investigate
their degradation as well. We also evaluated the effect of
temperature by comparing the results of experiments at 25 and 5 °C.
This research provided systematic and quantitative information
about the biodegradation process of the
oil components and the
dispersant products under different conditions, which could serve
as a reference for selecting a proper dispersant product to assist
oil spills cleanup activities.

▼ The Deepwater Horizon
Oil Spill in 2010 released approximately 5 million barrels of
oil into the Gulf of Mexico just as the nearshore and beach profile were recovering from winter storms. As a consequence,
oil mats and tar balls were trapped at depth within the beach and nearshore profile. Excavation of this buried
oil during subsequent storms creates the potential for the contamination of adjacent beaches and the degradation of marine ecosystems, which can in turn negatively impact local economies that depend on fisheries and tourism. The potential for
oil burial and persistence is dependent on three things: the physio-chemical nature of the
oil as it reaches the nearshore environment, the pre-existing morphology of the beach and nearshore, and the evolution of that morphology after the
oil is deposited. The depth at which the
oil is buried is also dependent on the beach profile during the time of the
spill. The purpose of this study is to characterize the alongshore variation in depth of activation on a Deepwater Horizon impacted section of Pensacola Beach, Florida with regards to the implications of
oil residence time. Ground- Penetrating Radar (GPR) surveys were conducted along two parallel 1-km transects adjacent to the swash zone and the dunes. Additional cross- shore transects were completed every 150 m from the base of the dunes to the top of the swash zone. Sediment cores were taken at the crossing points of the alongshore and cross-shore transects, to calibrate the GPR surveys and complete an elemental analysis for the identification of storm layers and the presence of buried
oil. Results will show implications for
oil residence time with regards to the evolution of the beach envelope.

▼ As part of the Rena Long Term Environmental Recovery Programme commissioned by the Ministry for the Environment in response to the grounding of the MV Rena on Astrolabe Reef (Otaiti), an experimental study of ecotoxicological effects was initiated to examine potential effects of major pollutants discharged from or associated with the Rena shipwreck. This project is one of the first examinations of ship wreck and
oil spill pollution in New Zealand. Research will aid responses to future
oil pollution events such as ship groundings and
oil industry pollution.
The container ship MV Rena ran aground on Astrolabe Reef in the Bay of Plenty in October 2011 and discharged approximately 350 tonnes of heavy fuel
oil (HFO). During the response HFO was treated with approximately 3 m³ of the
oil dispersant Corexit 9500 at sea. Other pollutants associated with the Rena grounding included general cargo and other goods classified as environmentally hazardous, in particular, 560 tonnes of sodium hexafluoroaluminate or cryolite. Given the almost total absence of toxicity data relevant to HFOs, Corexit 9500 and other contaminant mixtures on New Zealand marine species, this project sought to assess the acute sublethal toxicity of these contaminants to a range of culturally, ecologically and commercially important species.
Sub-adult snapper (Pagrus auratus), spotted wrasse (Notolabrus celidotus) and red rock lobster (Jasus edwardsii) were exposed to 1:1000 cryolite, 1:10000 HFO (HFO WAF), 1:400000 Corexit 9500 and 1:40 HFO/Corexit 9500 combination (HFO CEWAF: 1:10000 HFO, 1:400000 Corexit 9500) for up to 96 h followed by recovery for up to 10 d. These concentrations and exposure durations were viewed as being environmentally realistic. Fish were necropsied and examined for haematology and accumulation of polycyclic aromatic hydrocarbons (PAHs).
Exposure to toxicants caused no lethality but did indicate sub-lethal effects. Measurements of blood parameters indicated two main effects in fish of erythrocyte swelling and haemoconcentration. The overall pattern of response in fish appeared to be a greater degree of erythrocyte swelling in response to the HFO WAF treatment. HFO WAF and HFO CEWAF treatments caused changes in leukocyte differential counts indicating negative responses of immunosuppression in fish. Corexit 9500 and cryolite exposure caused negligible/minimal changes in haematology in all species. Haematological assessment of Jasus edwardsii indicated immune effects of HFO WAF, HFO CEWAF and cryolite exposure as evident by changes in differential haemocyte counts.
Bile PAHs in fish and red rock lobster reached levels several orders of magnitude higher than controls. Corexit 9500 increased PAH body burden when combined with
oil, however in fish it also appeared to accelerate depuration of PAHs during post-exposure recovery. Depuration was not as evident in red rock lobster. Exposure to HFO appeared to stimulate an increase in melanomacrophages in the spleen of Pagrus auratus. Overall HFO exposure with or without the addition of…

▼ The Deepwater Horizon oil spill in the Gulf of Mexico (GoM) raised an important question. What is the ecological impact of the oil, the dispersant, and the dispersed oil to the GoM ecosystem? Significant and varying research efforts have contributed answers to this question. However, to better understand the complete ecological consequences of the spill in the GoM, the impact of the spill at the base of marine food web should be examined. This research aims to understand impact of the spilled oil, South Louisiana crude oil (LSC), the chemical dispersant, Corexit® EC9500A, and the dispersed oil on phytoplankton communities in the GoM at individual, community, toxin-production, enzymatic, and gene-expression levels. At the individual level, phytoplankton size influenced tolerance to crude oil, but taxonomic group seemed to be a more predominant criterion. In general, diatoms showed better tolerance to crude oil than dinoflagellates. Naphthalene and benzo(a)pyrene cannot be solely used as surrogates to assess crude oil toxicity on phytoplankton. Community-level effects were investigated under oligotrophic and eutrophic conditions. Diatoms showed the greatest tolerance to crude oil exposures under every condition that was assessed. Nevertheless, different diatom groups had distinct responses under different nutrient regimes. The amount of nutrients greatly influences phytoplankton response during crude oil exposure. Crude oil also affects toxin production of two ecologically important toxic phytoplankton species of the GoM, Karenia brevis and Prorocentrum minimum. It was revealed that reactive oxygen species are activated in phytoplankton exposed to crude oil. Phytoplankton species also displayed signs of oxidative stress and damage in their lipid structure under crude oil exposure. A gene expression study indicated that crude oil does not cause significant difference in the expression levels of selected genes between the control group and samples treated with crude oil. This research provides essential data for impact assessment of oil spills and pollution on phytoplankton ecology and bloom dynamics in the GoM. These datasets contribute substantially to existing scientific knowledge about the region and provide baseline information for subsequent research efforts that seek to further understand the impact of oil on the marine planktonic ecosystem in the GoM.
