Summer phytoplankton production and transport along the shelf break in the Bering Sea

Ocean acidification and biologically induced seasonality of carbonate mineral saturation states in the western Arctic Ocean

“…Nutrient rich waters, sea ice formation and melt, and long hours of irradiance make the Bering Sea shelf a highly productive marine ecosystem [ Wyllie‐Echeverria and Ohtani , 1999]. At the shelf break, a “green belt” extends northward along the continental shelf, supporting a large population of seabirds, and marine mammals [e.g., Kinder and Coachman , 1978; Hansell et al , 1989; Springer and McRoy , 1993; Springer et al , 1996; Okkonen et al , 2004; Grebmeier et al , 2006b]. Given these conditions, and although supporting carbonate chemistry data is lacking, it is highly likely that Bering Sea phytoplankton PP preconditions the Chukchi Sea by enhancing the saturation states of surface waters flowing from the Bering Sea into the Chukchi Sea.…”

Benthic amphipod community in the northern Bering Sea: analysis of potential structuring mechanisms

“…The above production rates also show remarkable interannual continuity (Hansell et al 1993). In addition to local production, substantial amounts of phytoplankton appear to be transported into the Chirikov Basin in the Anadyr water (Hansell et al 1989). The combination of advection and high production leads to high carbon flux to the benthos, thus permitting dense concentrations of large ampeliscids to occur, which in turn provides favorable foraging habitat for gray whales.…”

“…The Chirikov Basin is an unusually productive region due to the transport of nutrient-rich Anadyr water northward from the Cape Navarin region through the Gulf of Anadyr and into the northern Bering Sea (Hansell et al 1989, Springer & McRoy 1993. The northward transport is due to differences in sea level between the Arctic Ocean and Bering Sea .…”

Influence of pycnocline topography and water-column structure on marine distributions of alcids (Aves: Alcidae) in Anadyr Strait, Northern Bering Sea, Alaska

“…The Bering-Anadyr straits region is highlyproductive, with annual rates of primary production estimated as great as 325 g C m -2 yr -1 (cf. McRoy et al 1972, Sambrotto et al 1984, Hansell et al 1989, Highsmith and Coyle 1990. This high productivity results from cold (0 to 2 °C), saline (32.7 to 33.0 %0 S), nutrient-rich water entrained by the Bering Slope Current from the continental slope and Anadyr Gulf, and then advected northward at mean speeds of 10 to 25cm s -1 .…”
