Abstract

This interdisciplinary and international project has recently been initiated mainly with IPY funding from Denmark and Greenland. In short the project investigates the linkage between ice sheet freshwater release to a fiord near Nuuk (South-western Greenland) and the resulting fiord circulation. The low density melt water draining into the innermost of the long fiord forms a brackish outward sloping top layer, which exits the fiord and is balanced by entrance of nutritious salty oceanic water below. Such nutritious water, in turn, favors marine production in the fiord. The perspectives of a warmer climate, where more ice sheet melt water will increase the marine production, is of vital interest to investigate for the Greenland society because the present export from the country is totally dominated by living resources of the oceans. This interdisciplinary research project involves scientists from Greenland, Norway, Denmark and USA. Scientific disciplines presently covered are; marine ecology (biological production), cryospheric sciences (ice sheet and snow-water release), pollution chemistry (separating present from ancient precipitation), marine geology (history of freshwater input), oceanography (fiord circulation), geodesy (cryospheric elevation changes), and hydrology (land runoff). First field results will be presented together with the perspectives for linking each fresh water component coming from land and ice to the observed freshwater budget in the fiord.
