Presentation Transcript

  1. BASIN trans Atlantic cruise with RV GO Sars Geir Huse & Webjørn Melle EURO-BASIN cruise planning meeting 29-30 September, London RV METEOR ‘Deep Convection’ Cruise 2012 EURO-BASIN Cruise Programme, 29-30 Sep 2011

  2. Overall research questions Ecosystem structure and functioning: How are ocean basins in the North Atlantic structured and, what are the key drivers affecting them? Comparative approach: What are the commonalities and differences in the structure and functioning of the Subpolar gyre, the Labrador, Irminger and Nordic Seas? Connectivity: What are the major oceanographic and biological interconnections between these basins? Ecosystem effects of climate variability and change: How is the distribution of water masses in the different basins and how does it affect the species distribution?
