    Introduction to variability of the North Atlantic and its marine ecosystems, 2000–2009, the proceedings of an ICES/NAFO symposium held in Santander, Spain, 10–12 May 2011

    An international symposium on decadal changes in the International Council for the Exploration of the Sea (ICES) and North Atlantic Fisheries Organization (NAFO) regions of the North Atlantic from 2001 to 2009, jointly sponsored by ICES and NAFO, took place in Santander, Spain, from 10 to 12 May 2011. During the period covered by the symposium, the upper ocean warmed, particularly in temperate and Arctic–boreal regions, and there were major biogeographic shifts and changes in the phenology of the biota that appear to be related to the physical changes.

    Liquid freshwater transport and Polar Surface Water characteristics in the East Greenland Current during the AO-02 Oden expedition
    ( 2008-01-09) Nilsson, Johan ; Bjork, Goran ; Rudels, Bert ; Winsor, Peter ; Torres, Daniel J.
    Dynamical features of the East Greenland Current (EGC) are synthesized from a survey conducted by the Swedish icebreaker Oden during the International Arctic Ocean - 02 expedition (AO-02) in May 2002 with emphasis on the liquid freshwa- ter transport and Polar Surface Water. The data include hydrography and lowered Acoustic Doppler Current Profiler (LADCP) velocities in eight transects along the EGC, from the Fram Strait in the north to the Denmark Strait in the south. The survey reveals a strong confinement of the low-salinity polar water in the EGC to the continental slope/shelf—a feature of relevance for the stability of the thermo- haline circulation in the Arctic Mediterranean. The southward transport of liquid freshwater in the EGC was found to vary considerably between the sections, rang- ing between 0.01 and 0.1 Sverdrup. Computations based on geostrophic as well as LADCP velocities give a section-averaged southward freshwater transport of 0.06 Sverdrup in the EGC during May 2002. Furthermore, Oden data suggest that the liquid freshwater transport was as large north of the Fram Strait as it was south of the Denmark Strait.
