Abstract:: The role of sloping topography in controlling the overturning of the North Atlantic will be examined using a hierarchy of isopycnic model experiments with realistic topography for idealised and realistic forcing. The study will focus on how sloping topography affects where water masses are formed, the communication of overturning signals via wave propagation, as well as the transport, recirculation and evolution of dense, water masses. The study will provide a context to interpret monitoring signals from RAPID identifying how overturning signals are communicated from high to low latitudes along sloping western boundaries. A tied studentship will examine how the circulation of North Atlantic Deep Water alters in a glacial environment, the separate effect of forcing and sea level changes, and the large-scale consequences for atmospheric CO2 uptake.
