A Major Ecosystem Shift in the Northern Bering Sea
Until recently, northern Bering Sea ecosystems were characterized by extensive seasonal sea ice cover, high water column and sediment carbon production, and tight pelagic-benthic coupling of organicExpand

Comparison of warm and cold years on the southeastern Bering Sea shelf and some implications for the ecosystem
The southeastern, middle shelf of the Bering Sea has exhibited extreme variability in sea ice extent, temperature, and the distribution and abundance of species at multiple trophic levels over theExpand

Cetacean Habitat Selection in the Alaskan Arctic during Summer and Autumn
Ten years (1982-91) of sighting data from aerial surveys offshore of northern Alaska were analyzed to investigate seasonal variability in cetacean habitat selection. Distinct habitats were describedExpand

Seasonality of blue and fin whale calls and the influence of sea ice in the Western Antarctic Peninsula
The calling seasonality of blue (Balaenoptera musculus) and fin (B. physalus) whales was assessed using acoustic data recorded on seven autonomous acoustic recording packages (ARPs) deployed fromExpand

Arctic marine mammals and climate change: impacts and resilience.
Evolutionary selection has refined the life histories of seven species (three cetacean [narwhal, beluga, and bowhead whales], three pinniped [walrus, ringed, and bearded seals], and the polar bear)Expand

Arctic marine mammal population status, sea ice habitat loss, and conservation recommendations for the 21st century
Abstract Arctic marine mammals (AMMs) are icons of climate change, largely because of their close association with sea ice. However, neither a circumpolar assessment of AMM status nor a standardizedExpand

A comparison of the physics of the northern and southern shelves of the eastern Bering Sea and some implications for the ecosystem
Abstract Sufficient oceanographic measurements have been made in recent years to describe the latitudinal variation in the physics of the eastern Bering Sea shelf and the potential impact of climateExpand

Impacts of changing sea-ice conditions on Arctic marine mammals
Arctic sea ice has changed dramatically, especially during the last decade and continued declines in extent and thickness are expected for the decades to come. Some ice-associated marine mammals areExpand

Marine mammals as ecosystem sentinels
Abstract The earth's climate is changing, possibly at an unprecedented rate. Overall, the planet is warming, sea ice and glaciers are in retreat, sea level is rising, and pollutants are accumulatingExpand
