In recent years, as the ice retreated beyond the continental shelf, more than 10,000 walrus "haul out" on shore in Alaska and in Russia, and thousands of walruses have been killed in stampedes as the animals crowded onto the shoreline in these extraordinary numbers. It has an area of 225,000 square miles (582,000 square km) and an average depth of 253 feet (77 m). Between

Unlike seals, walruses cannot swim indefinitely and rely on ice floes extensively for resting and as platforms from which to feed on mollusks and other benthic invertebrates. showed the Chukchi Sea to be strongly driven by the wind, but suggest Walruses have also suffered from population declines as feeding and nursing their young have grown increasingly difficult. But the Chukchi Sea is changing dramatically.

Its vast, shallow sea floor and seasonal ice cover provide nutrients and pristine habitat for a multitude of organisms, ranging from walruses to ice seals to whales to millions of seabirds to the top predator mammal, the polar bear. waters below. Included among these are marine feeding areas for Northern Fulmars and Short-tailed Shearwaters and nesting and feeding areas for huge colonies of Common Murres and Thick-billed Murres.

Kittlitz's Murrelets have undergone dramatic reductions in population in recent years. Endangered fin and humpback whales, and formerly endangered gray whales, feed in the Chukchi’s shallows, and up to 3,500 beluga whales use Kasegaluk Lagoon near Point Lay for feeding, calving, and molting.
In addition to seals, most of the Pacific walrus population uses the Chukchi Sea during the summer months. The heat can influence the ice. moorings measured water velocity, temperature and salinity on 3 major At least 15 species on Audubon's Alaska WatchList use the Chukchi, including Spectacled Eiders, which are listed as threatened under the ESA, and Yellow-billed Loons, which have been found to warrant ESA listing (but are not a study priority).

Year-round IUCN - Polar Bear Specialist Group - Chukchi Sea. Yet as the summer sea ice has retreated dramatically in recent years, especially off the coast of Alaska, polar bears are increasingly denning on coastal lands instead. Barrow Canyon, the Central Channel, Herald Valley and Long Strait).

The US Fish and Wildlife Service decided not to list the species under the Endangered Species Act, but it remains to be seen how changes in climate will affect this species. sections - one across the Bering Strait, one across the central Chukchi Other Chukchi ice seals include ribbon, bearded, and spotted seals.

The Chukchi is also important for whales. The US Fish and Wildlife Service is investigating listing the Pacific walrus under the ESA. The ice edge produces a rich profusion of phytoplankton, which is the base of the food chain for all marine and coastal Arctic wildlife and people, especially with a lack of sea floor predation by warmer water fish, such as salmon and pollock.
Чукча), are an indigenous people inhabiting the Chukchi Peninsula and the shores of the Chukchi Sea and the Bering Sea region of the Arctic Ocean within the Russian Federation. Our editors will review what you’ve submitted and determine whether to revise the article. Nests have been found inland in the DeLong Mountains and Lisburne Hills, and murrelets have been found up to 40-50 miles offshore, primarily in the Cape Lisburne area north of Point Hope. Polar bears are integrally tied to sea ice for hunting, resting, breeding, and denning. It has an area of 225,000 square miles (582,000 square km) and an average depth of 253 feet (77 m). One type, known as “Bering Sea Water,” is cool, salty, and rich in nutrients. Sea temperatures are rising, shorelines are dramatically eroding, and summer sea ice is receding to historic lows. The evidence of global climate change is evident here perhaps like no other place on earth. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox.
