Fluxes Across Sloping Topography in the North East Atlantic (FASTNEt project)

MarinePhysics with Plymouth University was aboard the RRS James Cook for the JC88 cruise to the Malin Shelf region as part of the FASTNEt project in Summer 2013. Further cruises to the Faroe-Shetland Channel (FSC) are planned for April and September 2014 aboard the FRV Scotia.

FASTNEt is a project that will obtain new information on exchange processes at the ocean and shelf interface. The reason a project of this nature is required is due mainly to our lack of understanding of variability in these mechanisms across inter-annual and seasonal time scales. The processes that impact upon the exchange of Temperature and Salinity will be focused on, and thus these properties will be used as proxies to give estimates of the exchange of other properties such as Carbon and nutrients. Shelf regions are key gateways for the fluxes of Nitrate and Phosphate required for global ocean productivity, and the processes being examined by this project are the drivers for nutrient transfer.

Perhaps the largest gap in our understanding of how shelf-edge exchange operates is quantifying the extent to which seasonal cycle of stratification influences the key mechanisms at work in these regions. The novel aspect of this project will be the ability to undertake sampling during all seasons without the limitation of being restricted to using manned vessels that are unable to operate during foul weather.
