The Laptev Sea is one of the main source regions of sea ice in the Arctic Ocean. Most ice forms in winter in a prominent, quasi-permanent flaw lead or polynya (region of open water), separating landfast from drifting sea ice. In winter 2003/2004 we have deployed two seafloor moorings in the polynya, equipped with sensors to continuously observe ice, water, and sediment properties. In parallel, ...

Sea-breeze dynamics in southern France is investigated using an airborne Doppler lidar, a meteorological surface station network and radiosoundings, in the framework of the ESCOMPTE experiment conducted during summer 2001 in order to evaluate the role of thermal circulations on pollutant transport and ventilation. The airborne Doppler lidar WIND contributed to three-dimensional (3-D) mapping of...

A patient with sea-blue histiocytosis in spleen and bone marrow with an accompanying hyperlipidaemia is described. The hyperlipidaemia was due to an increase in "free" cholesterol, lecithin, and triglycerides. Despite these findings lecithin-cholesterol acyl transferase activity was normal. Although the precise biochemical defect was not identified, there was a failure of transport of cholester...

The two-branched inflow of warm and saline Atlantic Water to the Arctic is the major contributor of oceanic heat to the Arctic climate system. However, while the Atlantic Water entering the Arctic through the Fram Strait retains a large part of its heat as it flows along the Arctic continental slope, the branch flowing through the shallow Barents Sea releases a substantial amount of heat to the...

[1] Salt release during sea ice formation in the Ross Sea coastal regions is regarded as a primary forcing for the regional generation of Antarctic Bottom Water. Passive microwave data from November 1978 through 2008 are used to examine the detailed seasonal and interannual characteristics of the sea ice cover of the Ross Sea and the adjacent Bellingshausen and Amundsen seas. For this period th...

This paper uses a static, small open-economy computable General Equilibrium (CGE) model of the Swedish economy to study the effects of consistent internalization of external effects from transport and manufacturing. We look at eight policy scenarios: first a fully implemented Social Marginal Cost Pricing (SMCP) in manufacturing, sea and air transport, road transport, and rail transport; and the...

The transforming gene product of the S13 avian erythroblastosis virus, env-sea, is a member of the growth factor receptor class of tyrosine kinases. The env-sea precursor protein gp155env-sea is proteolytically processed into the mature cleavage products gp85env and gp70env-sea, which are subsequently terminally glycosylated and transported to the cell surface. Previous studies have shown that ...

Fertilization changes the structure and function of the cell surface. In sea urchins, these changes include polymerization of cortical actin and a coincident, switch-like increase in the activity of the multidrug efflux transporter ABCB1a. However, it is not clear how cortical reorganization leads to changes in membrane transport physiology. In this study, we used three-dimensional superresolut...

The Northern Sea Route-a shipping highway running along the northern coast of Russia on the seas of the Arctic Ocean, linking the European and Far East ports, as well as the mouth of the navigable Siberian rivers into a single transport system. Otherwise, the main Russian naval communications in the Arctic. Particularly important are strategic factors related to geopolitical and transnational m...
