The University of Oxford Arctic Ocean Research Programme has an affiliate ARP project with a focus on the flux of freshwater from the western Arctic Ocean southwards to the Atlantic. though the Canadian Archipelago and particularly through the Nares Strait. This is an important component of the research being undertaken by the ARP consortium TEA-COSI. Working with Canadian researchers and utilising Canadian Coastguard icebrekers the programme undertook an extensive oceanographic study during summer 2012 and retrieved moorings inserted in 2009. The focus of the project is to utilise these data to develop more effective models of Arctic oceanographic processes.to feed into regional climate models developed through TEA-COSI and links to the Met Office and Hadley Centre.
