Net community production in the northeastern Chukchi Sea

Deep-Sea Research Part II: Topical Studies in Oceanography, 2009
To assess the magnitude, distribution and fate of net community production (NCP) in the Chukchi Sea, dissolved inorganic carbon (DIC), dissolved organic carbon (DOC) and dissolved organic nitrogen (DON), and particulate organic carbon (POC) and ...

Mollusks in the Northeastern Chukchi Sea

ARCTIC, 1994
Infaunal and epifaunal mollusks of the northeastern Chukchi Sea were sampled and 139 molluscan taxa were identified. The pattern of spatial distribution of molluscan species was determined by cluster analysis, which resulted in six infaunal and five epifaunal station groups. Species characterizing various faunal groups are defined.

A Coastal Jet in the Chukchi Sea

ARCTIC, 1980
Data collected in the nearshore region between Point Lay and Ice Cape, Alaska, support the thesis that a well-developed coastal jet is present during the summer. The temporal variability of the current is as predicted by theory. The physical characteristics of the region suggest a strong signal-to-noise ratio for the baroclinic coastal jet.

Biogeochemical processes in the Chukchi Sea

Lithology and Mineral Resources, 2007
Study of biogeochemical processes in water and sediments of the Chukchi Sea in August 2004 revealed atypical maximums of the concentration of biogenic elements (N, P, and Si) and the rate of microbial sulfate reduction in the surface layer (0–3 cm) of marine sediments. The C: N: P ratio in the organic matter (OM) of this layer does not fit the Redfield-

Chemistry of aerosols over Chukchi Sea and Bering Sea

Chinese Journal of Geochemistry, 2004
The contents of elements in aerosols sampled during the First Chinese Arctic Research Expedition (CHINARE-1) show great differences from one element to another. Na, K, Ca, Mg, A1, F, and C1 are the major components in the aerosols, whose contents are larger than 30 ng/m3. The chemical elements whose contents vary between 0.1–30 ng/m3 are Br, Sr, Cr, Ni,

Phytoplankton blooms beneath the sea ice in the Chukchi sea

Deep Sea Research Part II: Topical Studies in Oceanography, 2014
In the Arctic Ocean, phytoplankton blooms on continental shelves are often limited by light availability, and are therefore thought to be restricted to waters free of sea ice. During July 2011 in the Chukchi Sea, a large phytoplankton bloom was observed beneath fully consolidated pack ice and extended from the ice edge to 4100 km into the pack.

The South Chukchi Sedimentary Basin (Chukchi Sea, Russian Arctic)

2013
Abstract The South Chukchi Basin separates the late Mesozoic Chukotka Fold Belt from the Wrangel Arch and represents the northwestern continuation of the Hope Basin of the United States sector of the Chukchi Sea, which is filled with middle Eocene–Quaternary nonmarine, marine, and lacustrine rocks.

Fission Product Concentration in the Chukchi Sea

ARCTIC, 1964
Reports on concentrations of strontium-90, cerium-144, and promethium-147 in water samples collected 1959-1962, especially as indicating mass transport of ocean water. The 1959 Sr-90 fallout values were less than those reported from the northwestern Pacific and similar to values for the North Atlantic and mainland Alaska; but the 1960-62 values ...

Abundance and distribution of meiofauna in the Chukchi Sea

Acta Oceanologica Sinica, 2014
The metazoan meiofauna in the Chukchi Sea were collected from seven shallow water stations (depths ranging 46 to 52 m) and five deep sea stations (depths ranging between 393 and 2 300 m) during the 4th Chinese National Arctic Research Expedition in 2010.

Soundscape of the North-Eastern Chukchi Sea

The Journal of the Acoustical Society of America, 2012
The Chukchi Sea is a dynamic environment that cycles each year from open seas in summer to 100% ice cover in winter. The ice and sea conditions lead to a highly variable acoustic background. In summer the soundscape’s backdrop are wind and wave sounds typical of shallow seas.
