As last year, scientists from the GreenEdge project are in the little village of Qikiqtarjuaq. Dozens of experiments are carried out at the ice camp. Here is an account of a new series of activities to evaluate the amount of organic matter that is exported from the surface to the bottom of the ocean.
In the first meters of the water column, enough light makes it through the ice to maintain an active primary production.
