A subtropical water intrusion spring-event in the shelf-slope of the southwestern Bay of Biscay after strong wind-forcing pulses

Two consecutive multidisciplinary surveys, covering the north and north-western part of the Iberian shelf and slope during spring 2000, showed a dramatic change in the oceanographic conditions as a result of a southern water intrusion that replaced shelf and slope waters down to 300 m depth. The int...
