title: Bathymetric data from E4 Lake, Toolik Field Station, Alaska (2019).

description: Toolik Field Station is located in the foothills of the Brooks Range on Alaska's North Slope and is administered by the Institute of Arctic Biology at the University of Alaska Fairbanks (UAF). Toolik Field Station was first established to support an aquatic program designed to obtain base-line data on the North Slope and inland coastal ponds in 1975. Research has expanded over the years to include terrestrial, atmospheric, vertebrate and other taxa, making Toolik home to a long running and diversified body of arctic ecology. The station currently supports a long-standing and rapidly expanding community of scientists and research projects representing individual and collaborative efforts from United States and international institutions.
 Growth of Toolik-based science, the number of researchers, and the facility from a tented camp to a research station prompted the establishment of the Toolik GIS (Geographical Information Systems) and Remote Sensing (RS) Program as part of the 5 year Cooperative Agreement between the National Science Foundation (NSF) and the Institute of Arctic Biology, University of Alaska Fairbanks in 2001 (NSF Award Number 9981914). The mission of this Program is to facilitate and enhance arctic research, and to increase research and management efficiency, effectiveness and capability. This is accomplished: 1) through Information Technology (IT) and GIS-RS support of administrative and management infrastructure and production of planning tools for land management and permitting, and 2) through direct consultation and GIS, RS, and Global Posititioning System (GPS) support services to scientists. ToolikGIS provides a rich spatial geodatabase, project-specific data development, spatial analyses, consultation and documentation.

title: Sermilik, Greenland 3D iceberg data, summer 2017

description: This dataset is comprised of raw on-iceberg Geographic Positioning System (GPS) data, sound-speed corrected iceberg subsurface multibeam data (not corrected for iceberg movement), and iceberg surface three dimensional (3D) point clouds, constructed using structure from motion (SFM) of drone imagery. Data were collected during the summer of 2017 in Sermilik Fjord, East Greenland. Processing methods for these data are explained in the manuscript 'Measurements of iceberg melt rates using high-resolution GPS and iceberg surface scans' by Kristin M. Schild, David A. Sutherland, Pedro Elosegui and Daniel Duncan, published in Geophysical Research Letters in 2021 (doi: 10.1029/2020GL089765).
 The abstract and plain language summary for that paper are included below.
 Abstract
 Increasing freshwater input to the subpolar North Atlantic through iceberg melting can influence fjord-scale to basin-scale ocean circulation. However, the magnitude, timing, and distribution of this freshwater have been challenging to quantify due to minimal direct observations of subsurface iceberg geometry and melt rates. Here we present novel in situ methods capturing iceberg change at high-temporal and -spatial resolution using four high-precision GPS units deployed on two large icebergs greater than 500 meters (m) in length. In combination with measurements of surface and subsurface geometry, we calculate iceberg melt rates between 0.10–0.27 m/day over the 9-day survey. These melt rates are lower than those proposed in previous studies, likely due to using individual subsurface iceberg geometries in calculations. In combining these new measurements of iceberg geometry and melt rate with the broad spatial coverage of remote sensing, we can better predict the impact of increasing freshwater injection from the Greenland Ice Sheet.
 Plain Language Summary
 The acceleration of Greenland glaciers has led to an increase of icebergs discharged in nearby waters. As icebergs melt, they release freshwater into salty ocean waters, impacting local circulation. In order to understand how global circulation will change in the future, we need accurate iceberg melt rates. To do this, we use measurements of mass loss from on-iceberg GPS units, and 3D iceberg geometry constructed from aerial drone and subsurface sonar data. We found melt rates smaller than previous studies and strong evidence for variable overall melt rates with different keel depths and over time. This study is the first of its kind to calculate melt rates using exact iceberg geometry. To better predict iceberg impacts, future iceberg studies should take these geometry results into account.

title: Kangerlussuaq, Greenland, warming and exclosure experiment shrub abundance data 2003-2017

description: These data include annual peak abundances of two deciduous shrubs, dwarf birch (Betula nana) and gray willow (Salix glauca), sampled non-destructively from 2003-2017 near Kangerlussuaq, Greenland, as part of an ongoing experiment. The experiment involves exclusion of large herbivores (caribou and muskoxen) and passive warming according to the International Tundra Experiment protocol, and was motivated by an interest in investigating interactive and singular influences of herbivory and warming on plant abundance and community composition. Data include annual aboveground total abundance of each species on experimental plots under four treatment/control combinations: exclosed ambient, exclosed warmed, grazed ambient, and grazed warmed.

title: Transport of methane in open talik thermokarst lakes in discontinuous permafrost aquifers in Interior Alaska 2015-2017

description: As northern regions of the world experience warming climate, scientists look to permafrost, a crucial component of arctic and subarctic ecosystems, as a source and sink of atmospheric carbon. It is well-known that the thawing of permafrost from above as a result of warming climate is a considerable source of greenhouse gases. However, few studies have considered the production of methane, a potent greenhouse gas, beneath the permafrost. A rugged permafrost bottom is proposed to favor the storage of gas in "pockets" that have been formed through permafrost thaw and degradation from below. Sub (below)-permafrost methane can migrate to reach the atmosphere when connections between the sub-permafrost and supra- permafrost opens pathways from the pocket to the bottom of an open talik lake. We hypothesized that the migration of methane occurs through advection and diffusion as a dissolved gas and by movement as an immiscible fluid. Through measurement of environmental tracers in two thermokarst lakes in Goldstream Creek Basin, Fairbanks, Alaska, from 2015 to 2017, we found that advection was variable and was seasonally and climatically dependent demonstrating both upward and downward groundwater flow within our study lakes. Measurements of dissolved methane concentrations in the lakes demonstrated that diffusion of methane was not a significant transport mechanism in the groundwater-to-lake pathway due to the extreme temporal and spatial variability of methane concentrations. Immiscible flow of free-phase methane is likely the dominant transport mechanism but is dependent on the lake sediment composition and the formation of secondary pathways within the talik. Data obtained from this study allowed for a better understanding of methane transport and thermokarst lake dynamics.

title: Mycorrhizal root enzyme activity, fungal community, and soil chemistry in a long-term warming and fertilization experiment in Arctic tundra at Toolik Lake, Alaska (July 2017)

description: Arctic nutrient cycling is heavily influenced by mycorrhizal processes. With warming, deciduous ectomycorrhizal (EcM) shrubs are expanding across the tundra, potentially increasing the prevalence of ectomycorrhizae while decreasing other dominant mycorrhizal types. Because carbon (C) and nutrient cycling in Arctic tundra are tightly coupled, changes in nutrient cycling induced by these shifts in mycorrhizal regime and function could impact the large stocks of soil carbon. This project characterized the responses of EcM nutrient cycling to long-term warming and nutrient addition. All data was collected from the Arctic Long Term Ecological Research Network (LTER) warming and fertilization experiment established in 1989. We paired measurements of EcM root function with EcM fungal identity. This dataset consists of potential activities of 5 enzymes (leucine aminopeptidase, N-acetyl glucosaminidase, acid phosphatase, laccase, and peroxidase) measured on Betula nana root tips colonized by EcM; EcM root tip abundance and fungal identity; and soil chemistry. Fungal internal transcribed spacer region (ITS) sequences used for taxonomic identification are archived in GenBank under the accession numbers MT278352-MT278808.
