Changing Arctic Ecosystems: Enhancing forecasts of polar bear and walrus population response to a rapidly changing Arctic ecosystem (Modeling walrus-habitat associations and foraging energetics)

US Geological Survey (USGS) - The loss of sea ice during summer over the continental shelf of the Chukchi Sea in recent years has had visible effects on walrus distribution and behavior. The use of land haulouts by female and young walruses in the absence of offshore sea ice in recent years has resulted in direct calf mortality and almost certainly affects the availability of prey to walruses and, consequently, foraging...

National Assessment of Shoreline Change Project, Alaska

US Geological Survey (USGS) - Beach erosion is a chronic problem along most open-ocean shores of the United States. As coastal populations continue to grow, and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present shoreline changes. There is also need for a comprehensive analysis of shoreline movement that is regionally consistent. To meet...

Terrestrial linkage to climate and metazoan communities in coastal ecosystems of the Beaufort Sea

Alaska Ocean Observing System (AOOS) - This study targets how seasonally distinct terrestrial inputs of water and organic matter influence microbial and metazoan communities in coastal waters of the Alaskan Beaufort Sea. Coastal lagoons ecosystems along the Beaufort Sea shoreline support valuable biotic communities but it is unclear as to what extent terrestrial inputs serve as a food source and control community structure. While...

Development of Bias-Corrected Precipitation Dataset and Climatology for the Arctic Regions

UAF Institute of Northern Engineering (UAF INE) - Precipitation is one of the key components in hydrological modeling and process studies. It is also the most important variable in global change analyses, as change of precipitation will have a major impact on hydrology, climate and ecosystems. It has been recognized that significant (up to 100%) systematic errors (biases) exist in the gauge-measured precipitation records and these biases must...

Changing Arctic Ecosystems: Enhancing forecasts of walrus population response to a rapidly changing Arctic ecosystem (Modeling walrus population dynamics and bioenergetics)

US Geological Survey (USGS) - The Pacific walrus is a benthic feeding, ice-associated pinniped that ranges over the continental shelves of the Bering and Chukchi seas. The extent of summer sea ice in the Chukchi Sea has decreased drastically in recent years and this trend is projected to continue. Changes in the distribution of seasonal sea ice will likely affect walrus distribution and behavior and could affect the status...

Changing Arctic Ecosystems: Enhancing forecasts of polar bear and walrus population response to a rapidly changing Arctic ecosystem (Onshore polar bears)

US Geological Survey (USGS) - A new and major piece of our current research program is targeted at polar bears summering on land in Alaska. This is a new behavior, and current estimates suggest that during recent minimums of sea ice extent up to 10% of the Southern Beaufort (SB) sea population has remained on land rather than following sea ice into the deep polar basin. The focus of this work is to examine demographic,...
