Fungi in Bottom Sediments of the Chukchi Sea
Russian Journal of Marine Biology, 2019We present the first study on the quantity and diversity of the mycobiota in bottom sediments of the Chukchi Sea. During implementation of the RUSALCA-2012 program, 22 samples of bottom sediments from depths of 44–110 m were collected in late August–early September 2012. Fungi were isolated on agarized media (salinity 35 psu, temperature 6°C).

The Alaskan Chukchi Sea Shelf lies between 65°40′ and 73°00′N and 156°00′ and 171°00′W and covers an area of 580,000 km2 (Fig. 11-1). To the south the Chukchi Shelf is separated from the Bering Sea by a narrow constriction, the Bering Strait, and in the north it is bordered by an abrupt escarpment, the Beaufort Scarp, that descends to the floor of the ...

Deep-Sea Research Part II: Topical Studies in Oceanography, 2012 Activity concentrations of dissolved and particulate 210Pb and 226Ra in the water column were measured in the eastern Chukchi Sea during summer 2003. 234Th/238U disequilibria were used to estimate the scavenging fluxes of 210Pb from the water column to ...

Summertime circulation in the eastern Chukchi Sea
Deep Sea Research Part II: Topical Studies in Oceanography, 2015Abstract The transport of Pacific-origin water across the eastern Chukchi Sea during summer is studied using shipboard hydrographic and Acoustic Doppler Current Profiler data from multiple surveys. The study identifies two major transport pathways in this region.

Southeastern Chukchi Sea (Alaska) epibenthos
Polar Biology, 2004Epibenthos of the southeastern Chukchi Sea, inclusive of Kotzebue Sound, was sampled in 1976. Crustaceans dominated abundance while echinoderms, mainly sea stars, dominated biomass. Spatial distribution of fauna was determined by cluster analysis. Scavenger-predators were dominant trophic groups, although suspension feeders dominated some regions ...

Northward flow in the Bering and Chukchi seas
Journal of Geophysical Research: Oceans, 1987The ocean circulation on the Bering and Chukchi sea shelves is investigated using a barotropic numerical model. In the presence of the winter seasonal wind stress from the northeast, observed northward transport through Bering Strait of 0.6 Sv for the 8‐month winter season 1981–1982 can be driven by a sea level difference of 0.4 m between the Pacific ...

Southeastern Chukchi Sea (Alaska) macrobenthos
Polar Biology, 2006Macrobenthos in the southeastern Chukchi Sea, inclusive of the Chukchi Bight and Kotzebue Sound, were collected in 1985–1987 to determine factors influencing faunal distribution, abundance and biomass. Polychaetes, crustaceans, bivalve mollusks, and ophiuroid echinoderms dominated abundance.

Acoustic characterization of exploration drilling in the Chukchi and Beaufort seas
The Journal of the Acoustical Society of America, 2018This paper characterizes underwater sound levels produced by three drilling units during offshore exploration drilling at three sites in the Beaufort and Chukchi seas. Received levels and spectra are reported as functions of distance during drilling and excavation of mudline cellars (MLCs).

Microbial processes of the carbon and sulfur cycles in the Chukchi Sea
Microbiology, 2007The research performed in August 2004 within the framework of the Russian-American Long-term Census of the Arctic (RUSALCA) resulted in the first data concerning the rates of the key microbial processes in the water column and bottom sediments of the Bering strait and the Chukchi Sea. The total bacterial counts in the water column varied from 30 x 10(3)

Tritium and Plutonium in Waters from the Bering and Chukchi Seas
Health Physics, 1999During the summer of 1993, seawater in the Bering and Chukchi Seas was sampled on a joint Russian-American cruise [BERPAC] of the RV Okean to determine concentrations of tritium, 239Pu and 240Pu. Concentrations of tritium were determined by electrolytic enrichment and liquid scintillation counting.
