Community based walrus haulout management and protection

US Fish and Wildlife Service (USFWS) - Working with villages near walrus haulouts to help them lead haulout management and protection. To that end, we are sponsoring a workshop in Feb. in Barrow that will bring in leaders from a number of North Slope villages to discuss the issues, develop response plans, and increase communications.

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...

Changing Arctic Ecosystems: Enhancing forecasts of polar bear response to a rapidly changing Arctic ecosystem (Enhanced polar bear habitat models)

US Geological Survey (USGS) - Satellite radio telemetry has been an important tool for assessing distribution, activity levels and habitat use patterns polar bears. This information is necessary for development of polar bear energetic profiles. Since 1985, these data have been derived primarily from Doppler satellite telemetry. Doppler satellite telemetry provides relatively course-grained data on polar bear movements....

Changing Arctic Ecosystems: Enhancing forecasts of polar bear and walrus population response to a rapidly changing Arctic ecosystem (New methods to estimate demographic parameters of walruses)

US Geological Survey (USGS) - Nothing is known about the demographic rates of walrus, much less potential changes in these demographic rates caused by changing sea ice conditions due to climate change. Direct measures of walrus reproductive rates are extremely difficult to obtain due to the remote location of walrus calving habitats. Cow-calf ratios could be a useful index of walrus reproductive performance, but these are...

Marine Mammal Acoustics in the Bering Strait

Alaska Department of Fish and Game (ADFG), National Marine Fisheries Service NOAA (NMFS) - In this cooperative project, acoustic recording equipment and training is provided to Alaska Natives such that they can obtain in situ recordings of bowhead, gray, minke, and killer whales, ice seals (ringed, bearded, spotted and ribbon), harbor porpoise, and walruses in the Bering Strait region. Notes are taken on marine mammal presence and behavior observed visually during the acoustic...

Sea Ice for Walrus Outlook (SIWO)

Study of Environmental Arctic Change (SEARCH) - The Sea Ice for Walrus Outlook (SIWO), an activity of the SEARCH Sea Ice Outlook started in 2010, is a resource for Alaska Native subsistence hunters, coastal communities, and others interested in sea ice and walrus. The SIWO provides weekly reports from April through June with information on sea ice conditions relevant to walrus in the Northern Bering Sea and southern Chukchi Sea regions of...

Polar Bear and Walrus Response to the rapid decline in Arctic sea ice

US Geological Survey (USGS) - The Arctic is warming faster than other regions of the world due to positive climate feedbacks associated with loss of snow and ice. One highly visible consequence has been a rapid decline in Arctic sea ice over the past 3 decades - a decline projected to continue and result in ice-free summers likely as soon as 2030. The polar bear (Ursus maritimus) and the Pacific walrus (Odobenus rosmarus...
