  1. High Latitude GEOTRACES Atlantic workshop Oxford 10-13 Sept. Polar working group Per Andersson Kuria Ndungu Ben Reynolds Jana Friedrich Greg Cutter Russ Flegal Chris Measure (partly)

  2. Arctic rationale: • Input: shelf, river, atmos, groundwater • Pollutants; in ice, outflow through the Fram Strait • Contrasting Shelf environment /Siberian/Canadian • Major input to the N Atlantic • IPY work related to GEOTRACES (Ongoing and future) • SPACE, Aug.-Sept. 2007. M. Rutgers van der Loeff, P. Masque, H. de Baar, B. Moran) • ATOS, July 2007 Carlos Duarte • AGAVE, July 2007 H. Edmonds (hydrothermal) • Nordic LSBI , Aug-Sept 2008, P. Andersson, Ö. Gustafsson, Igor Semiletov • (CATS DAMOCLES) 2008 • Canadian GEOTRACE 2009, Beaufort Sea • Evaluation of IPY, Arctic transect in 2011/12 • Oden/Polarstern (Swe./Ger.)

  3. Antarctic • Rationale: • Inflow of ice vary around Antarctica, correlation with TEI • Fate of TEI across the Polar Front • High prod. Area close to the coast • Nd isotope variation in the bedrock around Antarctica • Calibration of paleop. • Three cruses: • Zero and Drake • Australian line • US 170 W • Oden. 5 year contract NSF-Swe. Science. • 2007-08, 20 days of science, Admundsen Sea. Track Punta Arenas to Ross Sea
