To elucidate these potential “bottom up” effects of climate changes to Arctic ungulates and evaluate the trophic mismatch hypothesis, the Arctic Landscape Conservation Cooperative (ALCC), the Bureau of Land Management (BLM), the U.S. Geological Survey (USGS), Teck, Inc., and the National Park Service provided funding in 2012-14 to incorporate the calving and summer range of the Western Arctic caribou herd (WAH) into an ongoing inter-agency research and monitoring effort to examine the influences of climate change on the nutrient dynamics of caribou forages. This work is leveraging existing projects on the North Slope of Alaska that are primarily funded through the USGS Changing Arctic Ecosystems Initiative. Field...
This project provides a better understanding how linkages among surface-water availability, connectivity, and temperature mediate habitat and trophic dynamics of the Fish Creek Watershed (FCW). These interrelated processes form a shifting mosaic of freshwater habitats across the landscape that can be classified, mapped, understood, and modeled in response to past and future climate and land-use change in a spatial and temporal context. Developing scenarios of freshwater habitat change in this context provides managers and scientists with a flexible template to evaluate a range of potential responses to climate and land-use change. Applying this approach in the FCW is made feasible because of the availability of...
Historically, available polar bear den habitat models have been based primarily on the presence of topographic features capable of capturing drifting snow. In any given season, however, the availability and precise location of snowdrifts of sufficient size to accommodate a bear den depends on the antecedent snowfall and wind conditions, and these vary from one year to the next. Thus, suitable topography is a necessary pre-condition, but is not sufficient to accurately predict potential den sites in a given year. To satisfy the requirements of agency and industry managers what is needed is a user-friendly decision-support tool that takes into account the current fall and early-winter meteorological conditions, and...
The Alaska Data Integration Working Group (ADIwg) Metadata Toolkit is an open source, suite of web applications for authoring and editing metadata for both spatial and non-spatial projects and datasets. The main goal of the toolkit is to promote the creation and use of metadata by lowering the level of technical expertise required to produce archival quality metadata.mdJSON is the metadata format ties the suite of tools together. The mdEditor is an open source client-side web application design to allow users to manage metadata for projects and data products. The mdEditor may be used to create mdJSON and interface with the mdTranslator to output metadata in multiple standards, including ISO 19115-2, 19115-1, 19110,...

The Arctic LCC has partnered with USGS to complete a feasibility study that will review current and past efforts to monitor thermokarst at broad spatial and temporal scales, compare relevance, cost, and strengths/weaknesses of the various approaches and techniques. Researchers have outlined potential study designs for monitoring thermokarst events that emphasize processes affecting large areas, or with a disproportionately large impact on fish and wildlife habitat quality. Information available in the final report includes: 1) review existing thermokarst monitoring methods via a literature review, 2) provide a brief description and review of thermokarst landforms and processes associated with permafrost degradation...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
