ObjectivesTo investigate the short term variability in the hydrography in an area south of Cape St. Vincent where previous observations had indicated an appreciable meandering in the Mediterranean outflow and the possibility of a deep eastward counter current below 1500m.
To make similar CTD and Thermistor Chain observations in an area where step layers are formed beneath the Mediterranean outflow.
