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.
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.
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.
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

The Bering Sea is very important to the seabirds of the world. Over 30 species of seabirds and approximately 20 million individuals breed in the Bering Sea region. Seabird species include
tufted puffins, the endangered
short-tailed albatross,
spectacled eider, and
red-legged kittiwakes. Many of these species are unique to the area, which provides highly productive foraging habitat, particularly along the shelf edge and in other nutrient-rich upwelling regions, such as the Pribilof,
Zhemchug, and Pervenets canyons. The Bering Sea is also home to colonies of
crested auklets, with upwards of a million individuals.
Two Bering Sea species, the
Steller's sea cow (''Hydrodamalis gigas'') and
spectacled cormorant (''Phalacrocorax perspicillatus''), are extinct because of

Pacific cod, several species of

red king crab and
snow crab.
Fish biodiversity is high, and at least 419 species of fish have been reported from the Bering Sea.
Fisheries
The Bering Sea is world-renowned for its productive and profitable fisheries, such as
king crab, opilio and tanner crabs, Bristol Bay salmon, pollock and other groundfish. These fisheries rely on the productivity of the Bering Sea via a complicated and little understood food web.
Commercial fishing is lucrative business in the Bering Sea, which is relied upon by the largest seafood companies in the world to produce fish and shellfish. On the U.S. side, commercial fisheries catch approximately $1 billion worth of seafood annually, while Russian Bering Sea fisheries are worth approximately $600 million annually.
The Bering Sea also serves as the central location of the Alaskan
king crab and
snow crab seasons, which are chronicled on the

Change
Because of the changes going on in the Arctic, the future evolution of the Bering Sea climate and ecosystem is uncertain. Between 1979 and 2012, the region experienced small growth in sea ice extent, standing in contrast to the substantial loss of summer sea ice in the Arctic Ocean to the north.
