Impacts of basin-scale forcing on the circulation of the Faroe-Shetland Channel
The investigation of the role of basin-scale forcing on the circulation of the Faroe-Shetland Channel (FSC) is important to further understanding of the inter-annual variability of the Atlantic water (AW) fluxes in this region. The FSC plays a key role in the transfer of warm and saline AW towards the Nordic Seas that is an integral part of the Atlantic Meridional Overturning Circulation which is projected to decline over the twenty-first century and might reduce the oceanic heat and salt transports towards the Arctic. So far little attention has been paid to the mechanisms driving the AW fluxes in the FSC and the reliable estimates of AW temperature and salt transports time series are lacking.
The aim of this project is to estimate a new time series of the AW fluxes based on the combination of hydrography and altimetry data. The AW fluxes time series are used to investigate the mechanisms affecting circulation pathways from the North Atlantic (NA) to the FSC and variability of the AW fluxes in the FSC.
The mechanisms considered in this project include: the influence of the local-scale wind stress and wind stress curl forcing; the North Atlantic Oscillation (NAO) and ocean gyre circulation forcing; and the impact of the pressure gradient across the Greenland-Scotland Ridge, reflected by the sea surface height changes. The analyses are considered based on the observational data and output from a high-resolution ocean model (VIKING20).
This project is linked with the European NACLIM project (FP7).
