UArctic Research Chair’s Arctic Freshening and Fertilization expedition aboard the US Coast Guards HEALY icebreaker has now passed into the marginal ice zone 50 miles N of Barrow, AK

The calm seas are perfect conditions to detect evaporation and freshwater injections from the coastal riverine plumes and the degree of ocean productivity and C source-sink properties across the entire NW Passage and across the entire Baffin Bay as we head west to east”
