| Abstract |
Classical models of the residual circulation in the North Sea predict a north-bound residual flow in the Southern Bight. A more refined model, taking into account the mesoscale Reynolds stress exerted in the mean on the residual flow by the non-linear interactions of mesoscale processes (tides, storm surges, etc.), shows on the contrary off the Belgian coast a south-bound coastal current in relation with a residual coastal gyre. Observations of the physico-chemical characteristics of coastal waters confirm the existence of the gyre. The dynamics of coastal ecosystems here are found to be determined by the gyre; successive stages of the pelagic rood chain displaying a typical spatial distribution along the deflected plume of the Scheldt estuary around the gyre 'outerlagoon'. |
