▼ Mineral-depositing hydrothermal ecosystems, such as the hot springs in Yellowstone National Park, provide an unparalleled opportunity to document how microbial biosignatures form and contribute to the body of evidence indicative of the microbial inhabitants of active hot springs. Mineralization of microbial communities in silica-depositing hot springs can result in the preservation of microbial biofacies in the geologic record. To determine the effects of prolonged aerial exposure on the preservation potential of mid-to-low temperature cyanobacteria dominated microbial communities that are typically permineralized in the siliceous sinter, modern biofacies samples of such communities were collected from the active and inactive parts of Queen's Laundry hot spring in Yellowstone National Park. The strategy of the research was to: (1) perform qualitative and quantitative characterization of structural and morphometric attributes of subaqueous and aerially exposed Calothrix biofacies samples collected from terraces; and (2) determine whether prolonged subaerial exposure affected the fidelity of morphological biosignatures (i.e., biofabrics and microbial cells) in the aerially exposed samples. To ensure that the permanently subaqueous and aerially exposed samples were comparable, a protocol developed to describe structural and morphological attributes of stromatolites was utilized to characterize the hot spring samples. Morphometric analysis of both types of Calothrix biofacies samples (i.e., partly silicified subaqueous and aerially exposed samples) revealed the presence of: distinct microbially influenced structures; thicker lamina at or near the base of the terraces; the greatest density of microorganisms in microbial structures; and increased microbial structure flatness as height of the microbial structures within the terrace proper increased. These characteristics were also used to provide a means to interpret the environmental conditions within which the terrace structures developed. To determine whether prolonged subaerial exposure affected the morphological fidelity of the biosignatures in the aerially exposed samples, the microstructure of these samples was studied in detail petrographically. A silica layer defined the boundary between laminae and was referred to as the "capping" silica deposit because it was found to "cap" all of the laminae in the Calothrix biofacies samples. The top most capping silica deposit of the aerially exposed Calothrix biofacies samples was found to be distinctly different from the capping silica deposits in the interior of the same sample and in the partly mineralized subaqueous Calothrix biofacies samples. The aerially exposed capping silica deposit was milky and glassy in appearance and contained fine laminations. The fine laminations were not found in any laminae of the biofacies samples. Another key finding of the project is a new evaluation of the preservation potential of the Calothrix terrace samples. Petrographic observations revealed that preservation… Advisors/Committee Members: Scott F. Burns.

▼ To better understand the diversity of mechanisms for stromatolite morphogenesis as well as the diversity of microorganisms and microbial metabolisms associated with stromatolites it is imperative to describe the biological attributes of the full diversity of "living" stromatolite-like geobiological structures worldwide. It is of additional interest to describe geographically and geochemically comparable ecosystems but lacking stromatolites to stromatolite-forming environments to unravel the geochemical and microbiological aspects of stromatolite morphogenesis. Here we present a living stromatolite system in a Yellowstone National Park (YNP) hot spring that exhibits features in contrast to many popularly studied modern stromatolite analogs. Most notably, the YNP stromatolites are more finely laminated than living marine stromatolites and may be a more suitable textural analog to finely laminated stromatolites found in the rock record. The YNP stromatolites are composed of silica-encrusted cyanobacterial mats. The predominant lithofacies of the YNP stromatolite is comprised of silica-encrusted filaments and is distinctly laminated. The laminated quality of the main lithofacies is due to an alternating-possibly on a diurnal cycle-growth orientation of filamentous cyanobacteria. Two cyanobacterial mat types grow on the stromatolite surfaces and are preserved as two distinct lithofacies. One mat is present when the stromatolites are submerged or at the water-atmosphere interface and the other when stromatolites protrude from the hot spring. The lithofacies created by the encrustation of submerged mats constitutes the bulk of the stromatolites, is comprised of silica-encrusted filaments, and is distinctly laminated. To better understand the cyanobacterial membership and community structure differences between the mats, we collected mat samples from each type. Molecular methods revealed that submerged mat cyanobacteria were predominantly one novel phylotype while the exposed mats were predominantly heterocystous phylotypes (Chlorogloeopsis HTF and Fischerella). The cyanobacterium dominating the submerged mat type does not belong in any of the subphylum groups of cyanobacteria recognized by the Ribosomal Database Project and has also been found in association with travertine stromatolites in a Southwest Japan hot spring. Cyanobacterial membership profiles indicate that the heterocystous phylotypes are 'rare biosphere' members of the submerged mats. The heterocystous phylotypes likely emerge when the water level of the hot spring drops. Environmental pressures tied to water level such as sulfide exposure and possibly oxygen tension may inhibit the heterocystous types in submerged mats. In contrast to living marine examples where the interplay of pCO2 and [Ca2+] is the main influence on microbial lithification, the lithifcation in the YNP system is driven by a rapid decrease in silica solubility between high-temperature subsurface water emitted from the hot spring vent and lower-temperature surface water.

▼ Wetlands provide vital habitat within functioning environments and act as landscape indicators by integrating catchment-scale hydrologic processes. Wetland drying during the past few decades in Yellowstone National Park's Northern Range has caused concern among National Park managers and the public at large. My research was initiated to develop an understanding of the processes controlling wetland water levels and contributing to wetland decline in the Northern Range. To do this I integrated analyses of hydrology, climate, soils, and vegetation. In 2009 I selected 24 study wetlands and instrumented each with an average of five shallow groundwater monitoring well-and-piezometer nests. To quantify historic wetland area I mapped hydric soils, analyzed aerial photographs, and identified geomorphic indicators of higher water. Vegetation was sampled to characterize wetlands and plant-water relationships, and I also conducted a soil seed bank study. The Trumpeter Lake focal site revealed groundwater changes through time and was used to identify the timescale on which an important wetland varies. Climate data indicated that warming and drying occurred during the 20th century, but that this pattern was within the natural range of variation for the study region during the past 800 years. Hydrologic data revealed that study sites included locations of groundwater discharge, recharge, and flow-through as well as water perched above the regional water table. Hydrologic regimes were classified using a shape-magnitude framework and seven wetland classes were characterized. Wetland classes exhibited variable hydrologic permanence within and between the two study summers. Aerial photographs and hydric soil delineation both confirmed formerly greater wetland abundance. These changes were linked to the wetland classes and the presence or absence of surface water outlets. Wetland plant species inhabited areas of distinct water table depth and variation, and can be used to infer subsurface hydrologic regime in the absence of extensive monitoring well networks. Continued monitoring of these wetland basins and their watersheds is critical to expanding our understanding of the processes supporting Northern Range wetlands and allowing us to better manage these valuable habitats.

▼ Discussions related to the adverse impacts associated with shore armor (i.e. seawalls and riprap) are a common topic within the coastal community. While many agree that the installation of these structures alters the shores geomorphic response, there is disagreement in the type and degree of response. Furthermore, studies that have delved into this topic have been conducted in numerous settings but have been confounded by a lack of data regarding shore morphologies prior to installation of these structures. At Yellowstone National Park, there is an opportunity to assess the impacts of shore armor quantitatively because the National Park Service requires detailed surveys in advance of all infrastructure improvement projects in an effort to determine the overall impacts of these projects on park environments relative to their benefits to park visitors and employees. The purpose of this study then was to contribute to this ongoing discussion of adverse impacts from shore armor by monitoring several non-engineered and engineered shore segments along the shore of Yellowstone Lake. For the purposes of this study, all shore segments that possessed shore armor (i.e. a seawall or riprap) were referred to as an engineered beach while any shore lacking a seawall or riprap was classified as a non-engineered shore segment. This study began with an effort to determine if there were geomorphic differences between several non-engineered and engineered shore segments located along the western and northern shore of Yellowstone Lake. This effort was accomplished by measuring cross-shore profiles, dry-beach widths and conducting a grain size analysis of the dry-beach sediments. Results from the initial survey conducted in July-August 2005 established that there were significant geomorphic differences between the non-engineered and engineered shore segments of Yellowstone Lake. Visual observations combined with surveyed cross-shore profiles, grain size analyses and dry-beach width measurements revealed that the non-engineered shore segments were indeed geomorphically different from the engineered segments. That is, the non-engineered shore segments displayed relatively wider beaches composed of sand to fine gravel with gently sloping profiles whereas the engineered shores were typified with angular L-shaped profiles with narrow dry-beach faces. In addition to the geomorphic differences, visual observations and analysis of the data revealed that the engineered shores were indeed adversely impacted by the shore armor through the processes of placement loss and profile deflation. A repeat survey was then conducted in the summers of 2006 and 2007 to determine the short-term variability of these non-engineered and engineered shore segments. Three years of data with a two-year interval indicated that there was a consistent difference in the geomorphology of the non-engineered and engineered shore segments. These differences were reflected in the cross-shore profile, the volume, and the dry beach width for all four study sites.… Advisors/Committee Members: Stephen K. Boss, Ralph K. Davis, John C.

▼ Aerial photographs and field sampling were used to compare aspen (Populus tremuloides) age structure and stand conditions on elk winter range in the northern Yellowstone ecosystem. The elk winter ranges studied were the northern range in Yellowstone National Park (YNP) and the Gallatin National Forest and the Sunlight/Crandall elk winter range in the Shoshone National Forest. I found significant differences when comparing aspen stands inside and outside of YNP borders. The aspen stands in the Gallatin and Sunlight/Crandall areas had a greater incidence of tall aspen suckers and stems in the 1-4, 5-9, and 10-19 cm DBH classes. Aspen stems within YNP had a significantly higher percentage of stems with high levels of bark damage (>66% of bark surface damaged on the lowest 3 m of stem) than aspen stems in stands in the Gallatin or Sunlight/Crandall. An aspen age structure was developed using 598 increment cores. The aspen age structure in YNP was significantly different than the age structures of the Gallatin and Sunlight/Crandall elk winter ranges. The Gallatin and Sunlight/Crandall areas did not have significant differences in their age structures. The greatest differences between YNP and the National Forest areas was in the younger age classes, measured as aspen stems originating between 1920-1989. Within YNP, I found that the aspen age structure, size class distribution, incidence of tall suckers, and the percentage of browsed suckers of the scree habitat type was significantly different than the xeric and mesic habitat types. Scree forms a "natural exclosure" where ungulate browsing is reduced. Aspen stands have successfully recruited new stems into their overstories in all habitat types from 1880-1989 on the Sunlight/Crandall elk winter range and the Gallatin's portion of the northern range. Within YNP, aspen stands successfully recruited new overstory stems between 1860-1929 in all habitat types. Since 1930, YNP aspen have successfully recruited overstory stems mostly in scree habitat type stands and other areas of reduced browsing pressure. I discussed several potential ecological factors impacting aspen overstory recruitment and conclude that changes in ungulate browsing patterns best explains the spatial and temporal pattern I observed.

▼ I conducted a multi-scale evaluation of aspen – bird relationships in the northern ungulate winter range of the northern Yellowstone ecosystem during June 2001-03. Questions addressed were: (1) Does bird diversity increase with conifer presence in aspen stands? (2) Given known habitat selection cues, are migrating birds passively intercepted by aspen patches oriented perpendicular to migratory direction of travel? (3) Are resident (short-distance migrant) birds passively intercepted by aspen patches? and (4) Given the dynamics of wolves, ungulates, and forage plants in the northern Yellowstone ecosystem, what is the present condition of aspen and cavity-nesting birds within Yellowstone National Park (YNP) and how will they change over the next 100+ years? Regression analyses of migratory bird diversity (species richness or Shannon-Weiner index) on measures of habitat heterogeneity (ratio of conifer to aspen canopy cover, or basal area) suggested no positive relationship with intermediate levels of conifer presence. Migratory birds were most diverse in pure aspen, and least diverse in pure conifer. I found a weak, but significant, positive relationship between most measures of habitat heterogeneity and resident bird diversity. Many residents were habitat generalists or conifer-associated species. To maximize bird diversity and aspen, managers may want to manage for pure aspen stands in a matrix that includes conifer habitat. Using model selection techniques, long-distance migratory birds did not show evidence of passive interception by aspen patches oriented against northerly or elevational direction of travel. Aspen patch area was most important for migratory birds, given the data and set of models analyzed. Resident (and short-distance migrant) birds showed a marked positive response to patch orientation relative to the elevational gradient of the northern range. Migratory birds appear not to be passively intercepted at high elevation sites such as YNP’s northern range. Short distance migrants appear to be passively intercepted. Northern range aspen stands within YNP have 10cm greater mean live and dead stem diameter, 80% more snags, and greater abundance of many cavity-nesting bird species than northern range stands outside YNP. These conditions fit a conceptual framework of interactions driven by a top-down ecosystem structure that predicts aspen and cavity-nester dynamics over several decades.

▼ As a nationally recognized symbol of perseverance and survival, the American bison (Bison bison) continues to be the focus of many conservation efforts. This is particularly true in Yellowstone National Park (YNP) where genetic diversity and population dynamics are threatened by the presence of Brucella abortus infection, the causative agent of brucellosis. To further complicate management efforts, the potential for transmission of B. abortus to livestock surrounding the park could have effects on human and animal health in addition to negative economic impacts. Genetic natural resistance to infectious diseases such as brucellosis has been examined in bison and other species. Consideration of using genetic natural resistance as a management tool within YNP relies on its applicability to the population and effectiveness in identifying susceptible or resistant animals. The aim of this study was to further investigate genetic natural resistance to brucellosis in bison using the prion protein gene (PRNP). This could provide a genetic management tool for future populations by identifying resistant and susceptible genotypes to brucellosis that governing agencies could screen when selecting animals for removal. Animals used in this study were part of the Bison Quarantine Feasibility Study (BQFS), which was conducted by state and federal government agencies to explore alternative options for bison that leave the protection of the park's perimeters as part of the Interagency Bison Management Plan (IBMP). After completing the study, the bison involved will be released into areas of their historic range and managed as a conservation herd. In addition to investigating genetic natural resistance, other genetic aspects were analyzed in this quarantine herd. We evaluated genetic diversity at 42 microsatellite loci representing each of the nuclear chromosomes in the bison genome. These markers allowed us to determine parentage which helped quantify the genetic diversity contained in the conservation herd. It was also important to understand the genetic diversity of the herd and to determine if any genetic characteristics such as cattle DNA introgression or low genetic diversity may threaten the protected status of this herd. Previously developed mitochondrial and nuclear DNA microsatellite markers were applied to determine if any introgression of domestic cattle DNA is presen. PRNP examination provided conflicting results from previous bison PRNP studies, justifying further research into the importance of PRNP in genetic natural resistance. As a conservation herd, this group of bison demonstrates high retention of unique YNP genetic diversity, high percentage of adult animals contributing offspring, and no evidence of cattle DNA introgression. This study explains support for using YNP bison as stocking animals for future satellite herds under the condition that BQFS protocol is followed. Results of these genetic analyses provide a thorough description of a quarantined herd of YNP bison destined for release to brucellosis-free public… Advisors/Committee Members: Salman, Mo (advisor), Hill, Ashley (committee member), Huyvaert, Kathryn (committee member), Rhyan, Jack (committee member).

▼ Yellowstone National Park (YNP) is a unique area for study due to the broad range of geologic and geomorphic agents that have sculpted this terrain over time. This research employed a multibeam echosounder (MBES) in Lewis Lake and Yellowstone Lake, in August 2011, to describe and interpret the geologic and geomorphic processes that have shaped Lewis Lake, as well as enhance our understanding of selected hydrothermally-active areas within Yellowstone Lake. Since the eruption that formed the present day caldera 640,000 years ago, dozens of smaller eruptions of differing compositions have occurred. The first-ever bathymetric and acoustic backscatter map of Lewis Lake shows that the lake morphology has been shaped by at least four separate volcanic events. These include tuff, rhyolitic and pyroclastic flows that have altered the hydrothermal plumbing of the lake bed. Using this data, a timeline for the evolution of Lewis Lake has been constructed that allows the geology of the lake floor to be integrated into existing ‘onshore’ outcrop studies. MBES mapping was also used to examine three areas hydrothermally active areas of Yellowstone Lake: the Inflated Plain, Elliot’s Crater, and the Stephenson Island depression chain. These surveys yielded high-resolution bathymetric maps. Additionally, acoustic returns from the water column were used to determine the location of active degassing areas, as well as rates of gas discharge from a hydrothermal crater in the Inflated Plain, Yellowstone Lake. Using the acoustic returns in the water column, a rate of 0.72-726.6 g m-2 day-1 was calculated to be erupting from this individual sub-aqueous crater. These rates are consistent with gas discharge directly measured in other hydrothermal vents around the world. These results have shown the potential for MBES technology not only to produce high-resolution bathymetric maps, but also aid in geologic mapping as well as geohazard evaluation in subaqueous hydrothermal environments.

▼ Yellowstone National Park (YNP) is one of the largest and most diverse hydrothermal areas on Earth. Extensive culture-independent studies in YNP thermal springs have shown dramatic taxonomic and metabolic diversity in microbial communities. We conducted a survey of bacterial communities along temperature gradients in three alkaline springs with similar geochemistries at the local scale. With these data, we investigated the influence of environmental variables on bacterial community diversity and assemblages along a broad temperature range using high throughput 454 pyrosequencing. Previous studies have suggested that pH is the driver of microbial diversity in thermal springs among geographical regions or at the global scale, whereas the temperature is an important factor controlling microbial diversity in springs within a similar pH range or within an individual geographical region. Our results revealed that temperature was the most important environmental variable to shape the structure of bacterial communities at the local scale. Similar community structure was observed in the sites with similar temperatures, irrespective of the origin of the thermal spring. The results of this study expand our current knowledge of the role of temperature in controlling community structure in YNP alkaline thermal springs. In addition to temperature, pH is also a crucial factor in determining microbial assemblages in thermal springs. Although thermal springs in YNP are characterized by a broad range of pH (1-10), the pH distribution is bimodal. Most of springs are either vapor-dominated acidic springs or water-dominated neutral to slightly alkaline springs. Yet the intermediate pH (e.g., pH 4-5) habitats have been overlooked. The dearth of information on microbial communities in the intermediate pH sites has still hindered an understanding of the whole picture of microbial diversity in YNP thermal springs. We conducted the first metagenomic investigation of microbial phylogenetic and functional diversity in a pH 4 and low temperature site. We uncovered a high proportion of Chloroflexi, Bacteroidetes, Proteobacteria and Firmicutes in this site. Functional comparison indicated that the community was enriched in the COG functions related to energy production and conversion, transcription and carbohydrate transport, possibly to result from high microbial dynamics. This is the first study to examine a pH 4 and low temperature habitat, which is a key step towards an understanding of the whole picture of microbial diversity in YNP thermal springs. Local environmental heterogeneity may also be responsible for the assemblages and distribution of some microbial groups. We examined microbial diversity and community composition in ten filamentous thermal springs with similar physiochemical properties in the Shoshone area by using the barcoded amplicon pyrosequencing approach. Despite all these samples from the same type of springs, statistical analyses suggest that the relatively small variation of environmental variables such as temperature,… Advisors/Committee Members: Takacs-Vesbach, Cristina, Sinsabaugh, Robert, Northup, Diana, Crossey, Laura.

▼ In 2009/2010 the Montana Yellowstone Archaeological Project (MYAP) conducted survey of the Crescent Hill chert outcrop (site 48YE729) in the northern portion of Yellowstone National Park. Occurring in a variety of colors and qualities, the chert precipitated within the Eocene-era Crescent Hill basalt formation. The procurement area encompasses 2,124.8 acres, with nine surface outcrops, five of which were clearly utilized by Native Americans during prehistory. With the materials previously being uncharacterized, hand samples representative of the outcrop areas were collected and analyzed using macroscopic, petrographic, and geochemical techniques. In doing this, the provenance of artifacts found in archaeological assemblages can be traced back to their original source outcrop area. Results show that the material is highly variable in appearance and elementally scattered, making it hard to differentiate Crescent Hill from other regional cherts. However, detailed macroscopic analysis provides an avenue for artifacts to be matched to hand samples from the source area. In doing this, elucidations regarding hunter-gatherer lithic technological organization and land-use can be made. Two archaeological sites in the lowest and driest portion of Yellowstone National Park, the Yellowstone Bank Cache Site (24YE355) and the Airport Rings Site (24YE357), show a heavy reliance on Crescent Hill chert (CHC). At both sites, CHC represents the second most abundant raw material type found in archaeological assemblages, next to Obsidian Cliff obsidian. Lithic raw materials from both source areas within well-dated hearth contexts indicate a temporal change in use of the materials from the Late Archaic to the Late Prehistoric periods, likely due to changes in human use of the landscape. Additionally, utilization of the two materials shows that prehistoric hunter-gatherers may have favored an embedded approach in obtaining materials from Crescent Hill, as opposed to Obsidian Cliff, representing a highly homogeneous isotropic source using a more direct approach of procurement. An examination of variables, including quality, abundance, distribution, and mode of occurrence of lithic raw material on the landscape were used to evaluate each procurement area. As reflected in a gravity model (Wilson 2007), Obsidian Cliff is superior in geological quality and ubiquitously found across the landscape in cultural contexts, making it the more desirable of the two sources.

Two models were successfully estimated using variables that may be extracted directly or easily calculated from standard GIS layers and other sources and they had `good' predictive ability with AUCs of 0.81 and 0.83. The ultimate intended use for the models is strategic program planning when information about future fire weather and event durations is unavailable and estimates of the average probabilistic shape and extent of large fires on a landscape are needed. Four primary objectives were to: estimate models from historical fire data that are appropriate for strategic program planning, incorporate the effect of barriers to the spread of fires across a landscape, account for the average effect of weather streams and management actions on large fires without using detailed information on weather, fire duration or management tactics, and investigate methods for addressing the spreading, connected nature of large fires on a landscape within a regression model. Models like these can provide finer detail than most landscape-wide models of burn probability and they have advantages over simulation methods because they do not require multiple runs of spread simulation models or information on fire duration or hourly weather events. To model burn probability patterns, I organized historical fire data from Yellowstone National Park, U.S.A. into a set of grids; one grid per fire. I incorporated explanatory variables such as fuel type, topography data and fire season indicators and I captured some spatial relationships through the use of distance, direction and other geometric variables. The data set observations are highly correlated and I investigated two approaches to account for and incorporate this correlation: one employed an autoregressive covariance structure and the other utilized a variable to account for the effects that neighboring cells may have on average burn probability. The two approaches yielded models with estimated coefficients that are consistent with fire behavior theory and that reflect how fires usually behave on the study site landscape. Both models compared well with the predictive ability of other fire probability models in the literature. Based on their predictive performance, this was a successful first attempt at addressing the research objectives and for estimating regression models to predict burn probability patterns for large fires.

▼ Support for charitable causes has long been a topic studied in the hopes of uncovering the reasons for donations and other support behaviors. However, holistic examination of support for places, such as parks, has been relatively untouched as an area of research. One such place where understanding such support is important is Yellowstone National Park, the first designated National Park and one of the most visited parks in the United States. A lack in adequate government funding to meet increasingly heavy visitation has led the park to increasingly rely on outside support for the park. The purpose of this study was to uncover the ways that several different supporter demographics provided support to Yellowstone and the reasons they provided this support. Participants were drawn from non-donor repeat visitors to the park, Yellowstone Association (YA) members, and Yellowstone Park Foundation (YPF) donors. Semi-structured in-depth interviews were utilized to reveal rich descriptions of these concepts in the supporters own words. Interviews included queries about visitation behaviors, participant definition of park support, donation or visitation specific queries tailored to participant groups, and a list of previously established support behaviors. Participants were recruited both in the park and by phone from a list provided by the YA and FPG and invited to participate in an interview at a later time. In total, 28 interviews were conducted, ten each from participants who identified themselves as repeat visitors and Association members and eight donors from the Foundation. Study results show that sharing park experiences, bringing newcomers to Yellowstone, and making monetary donations were the three most prominent ways that the participants supported the park. Moreover, personal values that matched park interests, altruism, and tangible benefits derived from giving were the most commonly given explanations for providing the varied forms of support. Repeat visitors were least likely to be aware of Yellowstone’s need for monetary support, and showed no altruistic giving tendencies. Because of this, one recommendation for park and non-profit managers is to better highlight the park’s need to this group. Managers could also pursue interactive ways to further engage these repeat visitors such that non-monetary support is more effectively leveraged for the future.

▼ I present for the first time a broad-scale assessment of dissolved organic matter in the continental hot springs of Yellowstone National Park. The concentration of dissolved organic carbon in hot springs is highly variable, but demonstrates distinct trends with the geochemical composition of springs. The dissolved organic carbon concentrations are lowest in the hottest, most deeply sourced hot springs. Mixing of hydrothermal fluids with surface waters or reaction with buried sedimentary organic matter is typically indicated by increased dissolved organic carbon concentrations. I assessed the bulk composition of organic matter through fluorescence analysis that demonstrated different fluorescent components associated with terrestrial organic matter, microbial organic matter, and several novel fluorescent signatures unique to hot springs. One novel fluorescence signature is observed exclusively in acidic hot springs, and it is likely an end product of thermally-altered sedimentary organic matter. This acid-spring component precipitates out of solution under neutral or alkaline conditions and characterization of the precipitate revealed evidence for a highly condensed aromatic structure. This acid-spring component serves as a reliable tracer of acidic, hot water that has cycled through the subsurface. Overall, dissolved organic carbon concentrations and fluorescent features correlate with the inorganic indicators traditionally used to infer spring fluid mixing in the subsurface. Further, the fluorescence information reveals subtle differences in mixing between fluid phases that are not distinguishable through classic inorganic indicator species. My work assessing dissolved organic carbon in the Yellowstone National Park hot springs reveals that the organic matter in hydrothermal systems is different from that found in surface waters, and that the concentration and composition of hot spring dissolved organic matter reflects the subsurface geochemical and hydrological environment.

▼ Life originated on early Earth, despite harsh, highly reducing conditions. Life may have also emerged on early Mars, when conditions on the two planets were similar (i.e. before atmosphere loss and desiccation). NASA’s 2020 Mars rover mission aims to identify biosignatures (i.e. evidence of life) in early Martian deposits. Potential exploration sites include extinct hydrothermal springs, due to their high habitability and preservation potential. This study aims to better understand biosignature preservation in hydrothermal systems analogous to those on early Mars (i.e. reducing and Fe-rich). Reactive oxygen species (ROS) are highly reactive molecules formed primarily by photochemical reactions. ROS are widespread, shape aquatic redox chemistry, and control biogeochemical cycles with redox-sensitive elements (Fe, S, O, and C). Of interest to this study, ROS can oxidize Fe²⁺ to Fe³⁺, which can adsorb or bind to negatively charged cell membranes. Rapid Fe³⁺-binding (i.e. entombment) can preserve complex organic molecules, or biomarkers. Recent studies have found that entombment by Fe³⁺, specifically, is key in biomarker preservation. In reducing systems, ROS are the primary oxidants and, thereby, determine Fe-oxidation rates and preservation potential. ROS formation is typically controlled by photo-reactions with dissolved organic carbon. However, Fe redox reactions more likely control ROS formation in these Fe-rich systems. Field and laboratory experiments were conducted at YSNP in relevant water compositions to better understand controls on ROS cycling. In-situ H₂O₂ cycles observed in these hydrothermal waters were comparable to other higher-temperature systems. Reactions with reduced metals from hydrothermal source waters were responsible for constant, “baseline” ROS production. Reaction rates varied based on particle size (particulate or soluble matter) and water composition. Fe speciation (photochemical reactivity), concentration, and solubility further determined ROS formation and decay rates. Specifically, photochemically active metal species enhanced both ROS formation and decay rates, depending on incident UV irradiance, and rates increased along with Fe concentration and solubility (i.e. acidic conditions). Low O₂ conditions slowed H₂O₂ decay, allowing H₂O₂ to accumulate. Hydrothermal reactants appear to produce more H₂O₂ per O₂^- molecule compared to other water compositions. Findings can improve our understanding of ROS as they relate to Fe entombment and biomarker formation.
