Marine Highways and Barriers: A Case Study of Limacina helicina Phylogeography Across the Siberian Arctic Shelf Seas

Diversity
The planktonic pteropod Limacina helicina is increasingly studied as a bioindicator of climate-driven changes in polar marine ecosystems. Although broadly distributed across the Arctic Basin and the North Pacific, its population structure and dispersal ...

Reconnaissance for a hydrological research in Laptev Sea and Lena Basin

Antarctic Record, 2000
A preparatory field investigation was carried out in July and August 1999 in the Lena basin and in the Laptev Sea, Russia. The hydrology of the region including the sea ice on the continental shelf is an important element in the global water circulation.

Paleogeographic Conditions for the Evolution of Sedimentary Cover in the Lapev Sea Based on Seismic Facies Analysis

Georesursy
The Laptev Sea is an area of active exploration for hydrocarbons; however, estimations of its hydrocarbon potential vary significantly, both in terms of total hydrocarbon quantities and their phase composition. This variability is due to the absence of a

Foraminifera of the Laptev Sea

Protistology, 2001
As a result of processing material of 6 Arctic expeditions Foraminifera fauna from the entire Laptev Sea within the limits of a wide range of depths (from 8 up to 3171 m) and salinity of bottom water (from 11 up to 35 per mille) was investigated. One hundred and thirty species were identified, of which 62 species are forms with agglutinated shell, and ...

New insights into the Laptev Sea tectonics

Interciencia
While the Laptev Sea sedimentary basin belonging to the shelfal area of the Arctic Ocean is promising in terms of hydrocarbon discoveries, its geologic complexity hinders petroleum geologic studies and estimation of its hydrocarbon potential. Existing contradictory views about the tectonic framework and evolution of the Laptev Sea cause considerable ...
