Deep water exiting the Nordic Seas : a pacemaker of North Atlantic circulation

This project focused on the deep water exported from the southern boundary of the Nordic Seas at the Greenland-Scotland Ridge through a series of sills. These so-called overflow waters contribute to the structure and strength of the overturning circulation that is fundamental to our climate system. Further these overflow waters contribute to the deep and long-term storage of heat and carbon that reduces atmospheric increases in heat and carbon and mitigate climate change.The project brought together Nordic experts at a three-day workshop in June 2021 to assess available observations and models regarding the properties, transports and fate of the overflow waters. In addition to identifying knowledge gaps the group proposed a list of recommendations for a strategy for observations and modelling in order to improve future monitoring and understanding
