Dynamic Processes and Links in the Arctic and Sub Arctic Oceans

Wednesday 23 May 2018 - 15:00
NOC Southampton - Henry Charnock Lecture Theatre (Waterfront Campus).

The dynamic processes and links between the Arctic and Sub Arctic Ocean in recent years will be examined by using the numerical modelling framework of the Nucleus for the European Modelling of the Ocean (NEMO). An overview of the features and set up used will be presented, such as the use of the Adaptive Grid Refinement in Fortran (AGRIF), coupling with a biogeochemical model (BLING) as well as an iceberg parameterization. Additionally, we examine the ability of NEMO to model: the stratification and formation processes of the Labrador Sea Water, freshwater outflow through the Arctic and Canadian Arctic Archipelago and investigate carbon, oxygen and nutrient interactions in these regions. We also examine the sensitivity of these systems by looking at variations of the North Atlantic Deep Water, Greenland Ice Sheet’s meltwater and icebergs pathways. Understanding the processes that drive warm ocean waters to marine terminating glaciers of the Canadian Arctic Archipelago and the Greenland Ice Sheet is also shown, as well as impacts on the large scale ocean circulations such as the Meridional Overturning Circulation.
