title: Collaborative Research: Year-round autonomous sampling of methane in Arctic lakes, Northwest Territories, Canada, 2011-2017

description: The investigators propose to measure methane concentrations in frozen lakes continuously throughout the Arctic winter using autonomous sampling devices, to more thoroughly address the variability in the methane flux from Arctic lakes to the atmosphere. Methane is a potent greenhouse gas, the release of which from Arctic sources is poised to increase with climate warming. This project will expand upon a successful pilot study that included the initial testing of autonomous continuous fluid sampler and sensor systems. The proposed expansion will involve additional capabilities and the deployment of a sampling unit in each of six small lakes along a north-south gradient in the Mackenzie River delta in the Canadian Arctic for a nine-month period, spanning the winter season. With these data the investigators aim to characterize the physical, chemical, and microbial conditions in the water column to elucidate hydrologic, microbial, and weathering processes during the winter season, when methane builds in lake water under the ice cover. The investigators hypothesize that sudden (week, days, or even hours) releases of methane, following spring flooding and ice cover breakup, produce a distinct atmospheric flux from Arctic lakes that would otherwise be missed, since most logistically reasonable sampling occurs in the summer months when methane concentrations in these lakes are low or below detection.
 The majority of methane flux to the Arctic atmosphere is estimated to come from soils and small lakes, although these estimates are based on few direct observations with large uncertainties. This proposed study, using in situ samplers and sensors, will allow an extensive microbial, gas and ion analytical program coupled with a network of physical and chemical sensor data to assess temporal conditions during winter months; to confirm fundamental processes and rates; to determine the interplay among microbial, geochemical and physical processes; and to develop a plan for a more inclusive study that takes advantage of low cost proxies for significant processes that best characterize temporal aspects of lake conditions. The project will enhance infrastructure for future research in the Arctic through the development of novel in situ sampling. The project will support several undergraduate and graduate students, providing valuable lab-based experience for students from non-research-intensive institutions. The investigators also will conduct two informal outreach activities to communicate the importance of Arctic climate change to primary school students while also teaching them about design and engineering. They also intend to work closely with Aurora College and Aurora Research Institute based in Inuvik, Canada, to engage First Nations youth.

title: Doctoral Dissertation Improvement Grant: The Archaeological Investigation of Erosion and its Effect on Social Processes in the Arctic

description: This award supports a Doctoral Dissertation Improvement project to investigate the relationship between erosion and economic inequality over the environmentally and socially dynamic first 500 years of Norse settlement in Hegranes, Skagafjörður, Iceland. The agricultural practices of the first settlers of Iceland, ca. 870 CE, caused widespread deforestation and soil erosion. Erosion moves sediments from one place to another, and can lead to either landscape degradation or augmentation. On Hegranes small abandoned farms lie near large successful farms that still operate today, and eroded areas are interspersed with productive grassland. This patchwork landscape allows investigation of erosion as related to farmstead abandonment and the development of social inequality. This research has implication for understanding how coupled human and environmental systems today might affect processes of social change.
 The researcher will use tephrochronology to compare the settlement sequence of small farms with associated environmental sequences of soil erosion and landscape change. The goal is to explore changes in number and distribution of small household farms, document processes of erosion, and investigate whether social reorganization of the landscape corresponds to increases in erosion. Larger, more powerful households likely benefited from abandonment of small farms, and this project will suggest how abandonment was managed to their advantage. This work will contribute to discussions about social and political consequences of human-initiated environmental change, focusing on unequal power relations between households that facilitate environmental degradation and social inequality.

title: SedCT: MATLAB tools for standardized and quantitative processing of sediment core computed tomography (CT) data collected using a medical CT scanner

description: This entry archives the SedCT MATLAB code, version 1.05, which is a MATLAB based application with graphical interface for processing of sediment core Computed Tomography (CT) data collected on a medical CT scanner. It was designed for use with products from the Oregon State University (OSU) College of Veterinary Medicine Toshiba 64 Slice medical CT scanner, but has been tested on other medical CT scanner systems. The program is documented by Reilly et al. (2017) and on the OSU Marine and Geology Repository website (www.osu-mgr.org/sedct). We also include sample CT data from a sediment core collected from Fish Lake, Utah (Reilly et al., 2018).
 Computed tomography (CT) of sediment cores allows for high-resolution images, three-dimensional volumes, and down core profiles. These quantitative data are generated through the attenuation of X-rays, which are sensitive to sediment density and atomic number, and are stored in pixels as relative gray scale values or Hounsfield units (HU). We present a suite of MATLAB™ tools specifically designed for routine sediment core analysis as a means to standardize and better quantify the products of CT data collected on medical CT scanners. SedCT uses a graphical interface to process Digital Imaging and Communications in Medicine (DICOM) files, stitch overlapping scanned intervals, and create down core HU profiles in a manner robust to normal coring imperfections. Utilizing a random sampling technique, SedCT reduces data size and allows for quick processing on typical laptop computers. SedCTimage uses a graphical interface to create quality tiff files of CT slices that are scaled to a user-defined HU range, preserving the quantitative nature of CT images and easily allowing for comparison between sediment cores with different HU means and variance.

title: Atmospheric tracers for Arctic wildfires, air pollution, atmospheric chemistry, and climate change at GEOSummit, Greenland, since 2018

description: There has been an unprecedented increase in Arctic wildfire occurrences in recent years. This Arctic Observing Network (AON) project focuses on the study of Arctic tundra wildfires through continuous observations of atmospheric fire tracers, including carbon monoxide, methane, and a series of volatile organic compounds (VOCs) monitored at the Greenland Environmental Observatory at Summit (GEOSummit). Observations will be applied in modeling research to simulate Arctic wildfires, and to assess climate-change induced increase in Arctic wildfires and their feedbacks on the Arctic environment. This dataset is an archive of methane, carbon monoxide, carbon dioxide, and VOCs (ethane, propane, iso-butane, n-butane, acetylene, iso-pentane, n-pentane, n-hexane, benzene, toluene) ambient air mixing ratios collected at GEOSummit since 2018. We aim to update this dataset regularly.

title: Collaborative research: What role do glaciers play in terrestrial sub-arctic hydrology?

description: The overall project assessed the linkages and controls of a subarctic glacier-permafrost hydrological system from a watershed-scale perspective using field measurements, remote sensing and numerical modeling. Jarvis Creek (634km2), which feeds the Delta and Tanana River in Interior Alaska, was studied as a proxy of the observed mountain glacier melting and permafrost degradation that has been documented across the Arctic region in recent decades. The specific objectives were to 1) assess the hydrologic fluxes (including streamflow source components), stores, pathways and the role of glacier wastage on watershed hydrology, through hydrologic and geochemical field measurements as well as numerical and statistical modeling; 2) quantify the effect of glaciers and permafrost on recent historical (1960-present) hydrologic fluxes and storage by combining remote sensing, field measurements of glacier mass balance, and hydrology with a heat- and mass transfer model, and 3) project the future hydrologic regime using custom-derived downscaled climate projections.
The purpose of this Ground-Penetrating Radar (GPR) data set was to 1) quantify winter snow accumulation hydrological contributions separately from the glacierized and non-glacierized regions of Jarvis Watershed; and, 2) estimate total glacier ice volume of Jarvis Glacier and, based on yearly mass balance calculations, estimate total future glacier contribution changes from Jarvis Glacier to hydrological discharge. Winter accumulation ranged between 1.1 to 1.9 m SWE during each of the three seasons. Jarvis Glacier ice volume calculated from geophysical surveys and a manually digitized glacier outline during late season 2015 was 1.16 km^3 within an area of 8.82 km^2.

title: Collaborative Research: Contrasting Under-Ice and Open-Water Phytoplankton Blooms in the Chukchi Sea, Arctic, 2014

description: Over the last several decades, Arctic Ocean ice cover has become substantially thinner and more prone to melting, extending the period of open water. Associated with the loss of sea ice has been an increase in light penetration and a dramatic rise in the productivity of phytoplankton. The PIs' primary objectives are to determine the spatial distribution of large under-ice phytoplankton blooms on the Chukchi Shelf and the physical mechanisms that control them. The project proposed herein will utilize new data obtained from both remote instrumentation (e.g. moorings and satellites) and an interdisciplinary ship-based field program to gain a better understanding of the physical/chemical conditions that favor under-ice bloom development as well as the physiological adaptations that allow phytoplankton to flourish beneath sea ice. Outreach and education components of this project include participation in Stanford's Summer Program for Professional Development for Science Teachers and Stanford's School of Earth Sciences high school internship program, a compilation of professionally written short stories in the website by the Woods Hole Oceanographic Institution group, and incorporation of results by the Cold Regions Research and Engineering Laboratory.

title: Collaborative Research: Observation and Prediction of Ocean Acidification in the Western Arctic Ocean - Impacts of Physical and Biogeochemical Processes on Carbonate Mineral States, 2011 - 2012

description: The investigators will assess ocean acidification in the western Arctic Ocean, using ship time that is currently scheduled for annual mooring turnarounds in the Beaufort Sea. On these cruises, in September of 2011-2013, the investigators will collect samples for measurement of carbonate system parameters, inorganic nutrients, dissolved oxygen, oxygen isotopes, and oxygen/argon ratios, as well as continuous underway measurements of dissolved oxygen, oxygen/argon ratios, and pCO2. These data will be used to gain insights and perspectives into the extent of ocean acidification in the western Arctic Ocean; the key physical, chemical, and biological processes influencing the saturation states of aragonite and calcite; and potential impacts to pelagic and benthic communities. Water column observations will be synthesized with data from the associated NSF AON (Arctic Observing Network)-funded mooring, including temperature, salinity, nitrate, oxygen, pCO2, and pH, as well as carbon and hydrographic data collected on other cruises in the region. During each field season the PI will travel to several native villages to discuss the potential impacts of ocean acidification at town meetings and in classrooms. The work will contribute to carbon cycle studies coordinated under a variety of science plans and implementation structures that aim to establish accurate estimates of carbon budgets and fluxes and the underlying mechanisms that regulate them. A postdoctoral scientist will participate directly in this work, and results will be incorporated in one undergraduate level course and two graduate level courses taught by the lead investigator.

title: Mooring Observations from the Atlantic Water Inflow Experiment (ATWAIN) from September 21, 2012 through September 19, 2013

description: The overall goal of this study is to obtain a quantitative description of the water mass composition, kinematics, and dynamics of the Atlantic water boundary current in the eastern Arctic Ocean over an annual cycle, in order to elucidate the role of the current in regulating the Arctic system. The project is part of a larger cooperative program entitled the Atlantic Water Inflow Experiment (ATWAIN), which is an international collaboration between six institutions: The Woods Hole Oceanographic Institution (WHOI), USA; the Institute for Marine Research in Bergen, Norway (IMR); the Norwegian Polar Institute (NPI); the University of Svalbard (UNIS); the University of Tromsø (UT); and the Institute of Oceanology Polish Academy of Sciences (IOPAS). The main goal of ATWAIN is to better understand how the Atlantic water spreads into the Arctic Ocean, including the manner in which it interacts with the pack-ice and how it is transformed within the Eurasian Basin. As part of our study, six moorings were deployed across the Atlantic water boundary current near 30E for a one-year period, from September 2012 to September 2013. WHOI provided the four offshore moorings in the array.

title: The Carbon Balance of Arctic River Deltas: Tundra Fire as an Agent of System Change, 2015-2016

description: The summer of 2015 was an extraordinary year for fire in the Arctic, including in the Yukon-Kuskokwim Delta, presaging a future where tundra and boreal fire is far more common. Remarkably, the area burned in the YK Delta in 2015 exceeds the total area burned from 1940-2014 combined. The response of the YK Delta in the first year post-fire will set the stage for longer-term changes in delta carbon storage and transport among tundra, aquatic and marine systems, and to the atmosphere. Quantifying carbon export and understanding the immediate ecosystem response to fire is critical because long-term recovery is, to a considerable degree, dependent on short-term responses. A major question that this research will address is how fire influences the amount and form of carbon transported from delta ecosystems seasonally and in the first year following fire. Ultimately, these results will inform long-term trajectories of the vulnerability and fate of delta carbon pools. This research will significantly improve our understanding of the role of fire in the loss of both modern and ancient carbon from arctic river deltas, which contain &amp;amp;gt;10% of the Arctic’s massive permafrost carbon store.
 This funding will allow project scientists to engage with Alaska Native faculty and students in STEM-focused teacher training programs at the tribal college in Bethel, which will provide teachers with experience conducting research on climate change and arctic system science and the opportunity to develop curriculum focused on climate change and the feedbacks that result from fire and other changes in ecosystems in the Yukon River Delta. This project will also improve the infrastructure for arctic research and teaching at a small Undergraduate Institution in central Minnesota.
 Arctic river deltas are hotspots for carbon storage, occupying &amp;amp;lt;1% of the pan-Arctic watershed but containing &amp;amp;gt;10% of carbon stored in arctic permafrost. They are also heterogeneous mosaics of linked terrestrial and aquatic ecosystems, and are susceptible to changes in land, river, and marine systems. The vulnerability of carbon stored in arctic river deltas is a major unknown and is critically important as climate warming and increasing fire frequency may make this carbon vulnerable to transport to aquatic and marine systems and to the atmosphere. The goal of this proposal is to examine the immediate effects of fire on carbon storage in the Yukon-Kuskokwim Delta and exchange between terrestrial and aquatic components of the Delta. By extension this work will yield critical insights into how the carbon balance of deltas in the arctic system will change over the coming decades as warming continues and fire frequency increases.

title: Collaborative Research: REU Site: Svalbard REU: Holocene and Modern Climate Change in the Norwegian High Arctic

description: Since 2003, the PIs have been administering an REU site in the Svalbard archipelago for motivated geoscience undergraduate students, directly involving them in important climate change research and exposing them to the challenges and rewards of
 conducting high latitude research. Funds are provided to continue the Svalbard REU program for another year, based on the success of the program. Student research focuses on the climatic and surficial processes that operate in rapidly changing
 glacial, lacustrine, and fjord systems that may, in turn, archive the signature of anthropogenic changes in the high Arctic. Students define their research questions and design specific testable hypotheses throughout the program, complete their
 research projects at their home institutions during the following academic year and present their results at a professional conference. Most alumni of the program have gone into graduate programs better prepared for fundamental research.
