Mitochondrial DNA Variation in Northwestern Bering Sea Walleye Pollock, Theragra chalcogramma (Pallas)

Environmental Biology of Fishes, 2004
Genetic variability of the highly valuable gadid species, walleye pollock, Theragra chalcogramma (Pallas 1811), from five spatially separated northwestern Bering Sea areas (Ozernoi Bay, Olutorskyi Bay, Koryak shelf, Navarin region, and Anadyr Gulf ) was investigated.

Direct evidence for northward flow on the northwestern Bering Sea shelf

Journal of Geophysical Research: Oceans, 1996
During the summer of 1994, a satellite‐tracked drifter transited from the southeastern Bering Sea slope through Bering Strait by a route westward along the slope and then northward through Anadyr Canyon and Strait. The trajectory emphasizes the importance of a western location of northward flow on the Bering Sea shelf.

Analysis of the genetic structure of northwestern Bering Sea walleye pollock, Theragra chalcogramma

Environmental Biology of Fishes, 2004
The intraspecific structure of major populations of the walleye pollock Theragra chalcogramma from the northwestern part of the Bering Sea was studied. Specimens from Navarin, Olyutor and Shirshov shoals were sampled in the 2001 spawning season. Preliminary cluster analysis (TREECON) of PCR-RAPD data revealed the existence of cluster with low level of ...

Specifics of the distribution of commercial fishes in the northwestern Bering Sea

Journal of Ichthyology, 2014
Data of trawling censuses (1996–2005) are used to analyze the specifics of the distribution of commercial fishes present in the northwestern Bering Sea in summer and autumn and forming accumulations in the waters of the Olyutorsky-Navarin region. Areas with maximum fish density usually have a temperature range of 2.4–4.0°C in near-bottom water layers ...

Distribution of cephalopods in the upper epipelagic northwestern Bering Sea in autumn

Reviews in Fish Biology and Fisheries, 2007
In the northwestern Bering Sea in autumn, the epipelagic cephalopod community was represented by the boreal fauna, and was found to be composed of three families and nine species of the order Teuthida: Gonatidae (Berryteuthis magister, Boreoteuthis borealis, Gonatopsis japonicus, Gonatus madokai, Gonatus kamtschaticus, Gonatus onyx, and Gonatus pyros),

Structure and spatial variation of bottom fish communities of the northwestern Bering Sea

Journal of Ichthyology, 2014
According to results of integrated record summer-autumn trawl surveys performed in 2004, 2005, and 2008 in the shelf-continental region of the northwestern Bering Sea from Cape Olyutorsky to Bering Strait in the range of depths 14–563 m, eight bottom communities of fish and fish-like were distinguished and their structure was described.

New Data on Soft Sculpin Malacocottus zonurus (Psychrolutidae) from the Northwestern Bering Sea

Journal of Ichthyology, 2019
Biological features of soft sculpin Malacocottus zonurus (Psychrolutidae) are described based on the analysis of samples from bottom trawl catches in the northwestern Bering Sea in July–August 1999 and 2001 at depths of 140–500 m.

Current state of Pacific cod stocks in the northwestern part of the Bering Sea and prospects for its fishery

Fisheries, 2023
The article presents data on the fishery and stock status of Pacific cod in the northwestern part of the Bering Sea for the period from 1968 to 2024. It is shown that the increase in commercial stocks of this species to an abnormally high level (1.1-1.6 million tons) was due to the warming of water masses in the north of the sea and the formation of an

Transport of copper from the Bering Sea to the northwestern North Pacific

Journal of Oceanography, 1986
Dissolved copper concentrations in surface waters of the Bering Sea ranged from 106 to 882 ngl−1. Higher concentrations were found in continental shelf waters. In the northwestern North Pacific dissolved copper ranged from 54 to 140 ngl−1. Particulate copper concentrations varied regionally and seasonally from 6 to 79 ngl−1.

Circulation of Waters in the Northwestern Part of the Bering Sea According to Satellite Data

Izvestiya, Atmospheric and Oceanic Physics, 2020
A study of water circulation in the northwestern part of the Bering Sea using AVISO satellite data on velocities of geostrophic currents from 2002 to 2017 showed a significantly variable dynamics of the surface waters. In January, the main current of the surface waters is directed toward the southwest along the continental slope in contrast to ...
