Carbon and nitrogen assimilation in the Bering Sea clams Nuculana radiata and Macoma moesta [PDF]

open access: yes, 2012
We analyzed bulk carbon and nitrogen stable isotope values (delta C-13 and delta N-15) of the benthic clams Nuculana radiata and Macoma moesta from the Bering Sea during controlled feeding experiments (spring of 2009 and 2010) using isotopically labeled ...

A Northern Snowmelt Model [PDF]

open access: yes, 1974
In early 1968, a large petroleum discovery was made in the Prudhoe Bay area of Alaska's Arctic Coastal Plain. This discovery has led Alaska into a period of development of unprecedented speed and magnitude.

Hypsometry and Volume of the Arctic Ocean and Its Constituent Seas [PDF]

open access: yes, 2002
This paper presents an analysis of the Arctic Ocean and its constituent seas for seafloor area distribution versus depth and ocean volume. The bathymetry from the International Bathymetric Chart of the Arctic Ocean (IBCAO) is used together with limits ...

Sedimentation processes on the Antarctic continental margin at Kapp Norvegia during the Late Pleistocene [PDF]

open access: yes, 1986
Sedimentological analyses concerning ice rafted debris, grain size distribution, biogeneous components, and clay mineral composition of four sediment cores from the Antarctic continental margin off Kapp Norvegia reveal a cyclical pattern of three ...

The application of ERTS imagery to monitoring Arctic sea ice [PDF]

open access: yes
The author has identified the following significant results. Because of the effect of sea ice on the heat balance of the Arctic and because of the expanding economic interest in arctic oil and minerals, extensive monitoring and further study of sea ice ...

Summer sea ice in the Northwestern Chukchi Sea observed in 2024 for the first time in 25 years

open access: yesnpj Climate and Atmospheric Science
The Arctic Ocean has seen a profound sea ice loss during the summer, with changes most pronounced in the Western Arctic. This has resulted in the Chukchi Sea, located just north of Bering Strait, being ice-free by the end of summer, i.e. September, since
