title: Modeled Carbon Responses of Tundra Ecosystems to Historical and Projected Climate

description: This data set contains the model output data of Terrestrial Ecosystem Model (TEM) simulations from 1920-2100 for both moist tundra and polar desert/alpine tundra for the Pan-arctic, compared to output for the Kuparuk River Basin (moist tundra). TEM simulates C and N fluxes and pools. 5,942 grid cells were used in the Pan-arctic simulation, of which 3,614 were considered polar desert/alpine tundra and 2,328 were considered moist tundra. All 19 grid cells in the Kuparuk simulation were considered moist tundra. The values of several ecosystem variables are compared between the Pan-arctic and Kuparuk. The results of this study are presented and discussed in McGuire et al. (2000), Modeling carbon responses of tundra ecosystems to historical and projected climate: sensitivity of Pan-arctic carbon storage to temporal and spatial variation in climate. Global Change Biology 6: 141-159. The simulations use the moist tundra and polar desert/alpine tundra calibrations developed by McGuire et al. (1992), based on data from Toolik Lake, Alaska.

title: Spatial and Temporal Influences of Thermokarst Failures on Surface Processes in Arctic Landscapes

description: Recent summaries of international research clearly document the past and future extent of climate warming in the Arctic. These summaries suggest that in the future, rising temperatures will be accompanied by increased precipitation, mostly as rain: 20% more over the Arctic as a whole and up to 30% more in coastal areas during the winter and autumn. These climate changes will have important impacts on Arctic Systems. Of direct interest to this research is the likelihood that warming will promote permafrost degradation and thaw. Formerly frozen soils may be further destabilized by increased precipitation, leading to hillslope thermokarst failures. Recent work has documented that thermokarst failures are abundant and appear to have become more numerous around Toolik Lake on the eastern North Slope and in the western Noatak River basin in Alaska. A widespread and long-term increase in the incidence of thermokarst failures may have important impacts on the structure and function of arctic headwater landscapes. This research will use a systems approach to address hypotheses about how thermokarst failures influence the structure and function of the arctic landscape. It will focus on the composition of vegetation, the distribution and processing of soil nutrients, and exports of sediments and nutrients to stream and lake ecosystems. Results obtained at this hillslope scale will be linked to patterns observed at the landscape scale to test hypotheses about the spatial distribution of thermokarst failures in the arctic foothills. It is important to understand these interactions because perhaps the greatest potential impacts of changing land surface processes and formation of thermokarst failures are feedbacks to the climate system through energy, albedo, water, and trace gas exchange. This research is designed to quantify linkages among climatology, hillslope hydrology, geomorphology, geocryology, community ecology of vegetation, soil nutrient dynamics, microbial ecology, trace gas dynamics, and aquatic ecology. It will employ a combination of field experimentation, remote sensing, and simulation modeling as a means to quantify these relationships.

title: Siberian boreal forest energy balance (ViPER (Vegetation Impacts on Permafrost) project), Cherskiy, Sakha Republic, Russia, 2016 - 2017

description: Energy balance dynamics in two stands of a Siberian larch forest located in the continuous permafrost zone near the Northeastern Science Station. Data are related to measures of radiative forcing, above- and below-ground micro-meteorological variables, ground heat flux, and sap flow measurements of tree transpiration. The dominant and only tree species is Larix cajanderi. The stands represent a high and low density forest and are located in the same fire scar and burned approximately 75 years ago. Mean tree age is 48 years old in both stands. Additional data includes root density measurements across two years, permafrost thaw depth, and soil characteristics. Tree allometry data is also included to facilitate scaling of sap flux measurements. The data is collected in association with the ViPER (Vegetation Impacts on Permafrost) project. The objective of this project is to examine the impacts of vegetation and ecosystem properties on active layer and permafrost thermal dynamics in order to better understand the vulnerability of permafrost to climate change.

title: Perceptions and implications of thawing permafrost and climate change in two Inupiaq villages of arctic Alaska

description: Survey responses of residents of the arctic Inupiaq villages of Anaktuvuk Pass (n=39) and Selawik (n=41), Alaska. The survey elicited local knowledge, perceptions, and speculations about current and future implications of thawing permafrost and other aspects of climate change for ways of life in these communities, focusing on subsistence, infrastructure, water resources, and transportation as key areas of potential impacts. Human dimensions data were collected and analyzed in conjunction with local thaw depth data as part of an interdisciplinary study of the implications of thawing permafrost and climate change for the social-ecological systems of two communities whose ways of life rely on close interactions with their local environments.

title: Breeding bird counts around Toolik Field Station, Alaska (2010-2017)

description: The Toolik Field Station Bird Monitoring Program was established in 2008 to monitor long term trends in arrival, departure, status and abundance of all birds breeding within the Toolik-centric region. Transects through the commonly occurring habitats were established. The overall protocol was adopted from the Alaska Landbird Monitoring Survey (http://www.absc.usgs.gov/research/bpif/Monitor/alms2.html). These data are from the bird count surveys in 2010-2017.
 The point count locations are situated 500 m apart, ten minutes are spent at each point count location and all birds seen and heard are recorded. The number of points within each transect was determined based on the natural features of the landscape. The data collected from these transects will be used to determine status and abundance of birds that breed in the Toolik area. The survey points are to be walked starting from the field station and moving away from the camp pad. Transects are marked on the map. The distances recorded from 2010-2011 were intervals; from 2012 onward, the distances recorded are actual distances.

title: Marine Mammal sighting data from cruises in the Pacific Arctic, 2009-2018, from Distributed Biological Observatory (DBO) Regions

description: The Pacific Arctic region (PAR) extends from the northern Bering Sea to the Arctic Ocean Basin, and it is experiencing major reductions in seasonal sea ice and increases in sea surface temperatures. Within the PAR, the northern Bering and Chukchi Seas are among the most productive marine ecosystems in the Arctic and are important carbon sinks and seasonal sources of organic materials. These recent shifts in seasonal sea ice cover are having profound consequences for seasonal phytoplankton production as well as to intimately linked higher trophic levels, including food harvested locally for subsistence. Key uncertainties remain as to how the marine ecosystem will respond to seasonal shifts in the timing of spring sea ice retreat and/or delays in fall sea ice formation. Productivity may change as sea ice declines and penetration of sunlight into open water increases, but the trajectory of changes to food web structure are unclear. Many organisms, from plankton to top predators are changing their distribution, migration and foraging patterns. A number of marine sites in the Pacific Arctic have high biomass, both in the water column and on the seafloor and are focused foraging points for apex predators. Several of these sites have been identified and re-occupied seasonally and interannually during multiple international cruises as part of the Distributed Biological Observatory (DBO) network. The DBO observational data documenting the importance of these ecosystem “hotspots” provide a growing marine time-series from the northern Bering Sea to Barrow Canyon at the boundary of the Chukchi and Beaufort seas, and across the Beaufort Sea to Amundsen Gulf. In US waters, these sites are DBO1 (south of St. Lawrence Island, DBO2 (Chirikov Basin north of SLI), DBO3 (southern Chukchi Sea), DBO4 (central Chukchi Sea), DBO5 (upper Barrow Canyon) , DBO6 (Beaufort Sea shelf break at ~152W). 
 As part of DBO efforts, marine mammal visual detections have been obtained from any research voyage with an on-board observer and sightings within DBO regions 1-6 have been highlighted.

title: RUI: Controls on methanogenesis, methane oxidation, and consumer utilization of methane-derived carbon in arctic lakes

description: Investigators from the University of North Carolina Greensboro have received funding to determine the importance of methane cycling in food webs of Arctic lakes. The main hypothesis is that the production, oxidation, and incorporation in to food-webs of carbon derived from methane is greater than for carbon produced by photosynthesis in the numerous small, shallow lakes of the Arctic. The project will develop a novel, integrated understanding of the energy and carbon linkages among methane producers, methane oxidizing bacteria, and higher trophic levels in rapidly changing Arctic lake ecosystems.

title: Collaborative Research: Cold-season gas exchange of arctic plants - resolving winter carbon and water balances of Alaskan arctic tundra

description: Investigators from the University of Alabama Tuscaloosa and Florida International University have received funding to investigate physiological processes of arctic tundra vegetation during the winter. The study will increase our understanding of physiological processes of arctic tundra vegetation under snow during the cold season and increase our knowledge of how these processes contribute to the carbon cycling and climate change. The project will investigate cold season plant physiology, carbon acquisition under snow, carbon turnover, and sources of water for the plants during the cold season, mortality, and respiration rate sensitivity to predicted changes in temperature. The results are expected to provide new insights into plant physiology and carbon dynamics of two tundra ecosystems during the cold season.
