The Bering Sea is named after Vitus Bering, a Danish navigator in Russian service, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean.ENCYCLOPEDIA,www.britannica.com/biography/Vitus-Bering, Vitus Bering, Encyclopaedia Britannica, 2018-12-21, The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over {{Convert|2000000|km2|sqmi|sp=us}} and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Bering Sea to the Arctic Ocean’s Chukchi Sea.ENCYCLOPEDIA, Area of Bering sea,www.britannica.com/place/Bering-Sea, Encyclopaedia Britannica, 2018-12-21, Bristol Bay is the portion of the Bering Sea between the Alaska Peninsula and Cape Newenham on mainland Southwest Alaska.The Bering Sea ecosystem includes resources within the jurisdiction of the United States and Russia, as well as international waters in the middle of the sea (known as the “Donut Hole“WEB, North Pacific Overfishing (DONUT),www1.american.edu/ted/donut.htm, Trade Environment Database, American University, 13 August 2011, dead,www1.american.edu/TED/DONUT.HTM," title="web.archive.org/web/20110409225847www1.american.edu/TED/DONUT.HTM,">web.archive.org/web/20110409225847www1.american.edu/TED/DONUT.HTM, 9 April 2011, ). The interaction between currents, sea ice, and weather makes for a vigorous and productive ecosystem.

History

Most scientists think that during the most recent ice age, sea level was low enough to allow humans to migrate east on foot from Asia to North America across what is now the Bering Strait. Other animals including megafauna migrated in both directions. This is commonly referred to as the “Bering land bridge” and is accepted by most, though not all scientists, to be the first point of entry of humans into the Americas.There is a small portion of the Kula Plate in the Bering Sea. The Kula Plate is an ancient tectonic plate that used to subduct under Alaska.Steinberger, Bernhard, and Carmen Gaina Geology 35 (5) 407-410, 2007 Plate-tectonic reconstructions predict part of the Hawaiian hotspot tract to be preserved in the Bering SeaOn 18 December 2018, a large meteor exploded above the Bering Sea.

Ecosystem

The Bering Sea shelf break is the dominant driver of primary productivity in the Bering Sea.JOURNAL, 10.1111/j.1365-2419.1996.tb00118.x, The Bering Sea Green Belt: Shelf-edge processes and ecosystem production, Fisheries Oceanography, 5, 3–4, 205, 1996, Springer, A. M., McRoy, C. P., Flint, M. V., 1996FisOc...5..205S, This zone, where the shallower continental shelf drops off into the North Aleutians Basin is also known as the “Greenbelt”. Nutrient upwelling from the cold waters of the Aleutian basin flowing up the slope and mixing with shallower waters of the shelf provide for constant production of phytoplankton.The second driver of productivity in the Bering Sea is seasonal sea ice that, in part, triggers the spring phytoplankton bloom. Seasonal melting of sea ice causes an influx of lower salinity water into the middle and other shelf areas, causing stratification and hydrographic effects which influence productivity.JOURNAL, 10.1175/1520-0485(1979)0092.0.CO;2, A Structural Front over the Continental Shelf of the Eastern Bering Sea, Journal of Physical Oceanography, 9, 1, 79, 1979, Schumacher, J. D., Kinder, T. H., Pashinski, D. J., Charnell, R. L., 1979JPO.....9...79S, free, In addition to the hydrographic and productivity influence of melting sea ice, the ice itself also provides an attachment substrate for the growth of algae as well as interstitial ice algae.JOURNAL, Olsen, Lasse M., Duarte, Pedro, Peralta-Ferriz, Cecilia, Kauko, Hanna M., Johansson, Malin, Peeken, Ilka, RóżaÅ„ska-Pluta, Magdalena, Tatarek, Agnieszka, Wiktor, Jozef, Fernández-Méndez, Mar, Wagner, Penelope M., Pavlov, Alexey K., Hop, Haakon, Assmy, Philipp, 2019-07-02, A red tide in the pack ice of the Arctic Ocean, Scientific Reports, 9, 1, 9536, 10.1038/s41598-019-45935-0, 2045-2322, 6606610, 31266996, 2019NatSR...9.9536O, Some evidence suggests that great changes to the Bering Sea ecosystem have already occurred. Warm water conditions in the summer of 1997 resulted in a massive bloom of low energy coccolithophorid phytoplankton (Stockwell et al. 2001). A long record of carbon isotopes, which is reflective of primary production trends of the Bering Sea, exists from historical samples of bowhead whale baleen.JOURNAL, 10.4319/lo.2000.45.2.0459, Declining carrying capacity in the Bering Sea: Isotopic evidence from whale baleen, Limnology and Oceanography, 45, 2, 459–462, 2000, Schell, D. M., 2000LimOc..45..459S, free, Trends in carbon isotope ratios in whale baleen samples suggest that a 30–40% decline in average seasonal primary productivity has occurred over the last 50 years. The implication is that the carrying capacity of the Bering Sea is much lower now than it has been in the past.

Biodiversity

The sea supports many whale species, including the beluga, humpback whale, bowhead whale, gray whale and blue whale, the vulnerable sperm whale, and the endangered fin whale, sei whale and the rarest in the world, the North Pacific right whale. Other marine mammals include walrus, Steller sea lion, northern fur seal, orca and polar bear.JOURNAL, Citta, John J., Burns, John J., Quakenbush, Lori T., Vanek, Vicki, George, John C., Small, Robert J., Heide-Jørgensen, Mads Peter, Brower, Harry, Potential for bowhead whale entanglement in cod and crab pot gear in the Bering Sea, Marine Mammal Science, 30, 2, 445–459, en, 10.1111/mms.12047, 12 June 2013, WEB, Humpback Whales in Alaska,www.whale-watching-alaska.com/whale/humpbackwhalesalaska.html, www.whale-watching-alaska.com, 24 April 2018, The Bering Sea is very important to the seabirds of the world.

The Bering Sea is also home to colonies of crested auklets, with upwards of a million individuals.{{citation needed|date=May 2018}}Two Bering Sea species, the Steller’s sea cow (Hydrodamalis gigas) and spectacled cormorant (Phalacrocorax perspicillatus), are extinct because of overexploitation by man. In addition, a small subspecies of Canada goose, the Bering Canada goose (Branta canadensis asiatica) is extinct due to overhunting and the introduction of rats to their breeding islands.The Bering Sea supports many species of fish, some of which support large and valuable commercial fisheries. Commercial fish species include Pacific cod, several species of flatfish, sablefish, Pacific salmon, and Pacific herring. Shellfish include red king crab and snow crab.WEB,www.adfg.alaska.gov/index.cfm?adfg=commercialbyareaaleutianislands.main, Bering Sea & Aleutian Islands, Alaska Department of Fish and Game, April 4, 2020, Fish biodiversity is high, and at least 419 species of fish have been reported from the Bering Sea.

Fisheries
