Description
Summary:Primary Objectives- Describe and quantify the present strength and variability of the circulation and oceanic processes of the Nordic Seas regions using primarily observations of the long term spread of a tracer purposefully released into the Greenland Sea Gyre in 1996.- Improve our understanding of ocean processes critical to the thermaholine circulation in the Nordic Seas regions so as to be able to predict how this region may respond to climate change.- Assess the role of mixing and ageing of water masses on the carbon transport and the role of the thermohaline circulation in carbon storage using water transports and mixing coefficients derived from the tracer distribution.Specific ObjectivesPerform annual hydrographic, chemical and SF6 tracer surveys into the Nordic regions in order to:- Measure lateral and diapycnal mixing rates in the Greenland Sea Gyre and in the surrounding regions.- Document the depth and rates of convective mixing in the Greenland Sea using the SF6 and the water masses ...
