Water Retention over Flemish Cap

Part of the NATO ASI Series book series (volume 7)

Abstract

Current meters, T-S analysis, and surface drifters indicate fresh water is retained in a slow gyre over Flemish Cap. Fitted annual cycles of salinity in the top 100 m are used in a simple compartment model to provide a salt flux estimate. About 50% of Cap surface waters are replaced each month. North Atlantic Current water does not influence Cap water composition. Computing heat fluxes from the salt flux predicts the correct phase and appropriate amplitude and mean for the solar heating cycle.
