Rapid Climate Change (RAPID) was a £20 million, six-year (2001-2007) programme for the Natural Environment Research Council. The programme aimed to improve the ability to quantify the probability and magnitude of future rapid change in climate, with a main (but not exclusive) focus on the role of the Atlantic Ocean's Thermohaline Circulation.
The Barents Sea is an important site for the production of dense intermediate water. Up to one half of this intermediate water flows into the North Atlantic over the Scotland-Greenland Ridge, constituting an important branch of the global thermohaline circulation. The presence of numerous coastal polynyas and the relatively low river input into the Barents Sea explain why this region is a significant site for water for water mass transformation. Parameterisations for dense water production in polynyas for application in non-polynya resolving ocean circulation models, were developed and tested in a coupled sea ice-shelf sea model of the Barents Sea. The latter were used to study present day water mass transformation processes and to predict how they will change in a warmer climate.
