S-CHLOROPHYLL SQUIRTS IN THE CHILEAN COAST: A SEAWIFS PERSPECTIVE
Squirts can be defined as one-way jets, transporting coastally upwelled water to the deep ocean and terminating in a counterrotating vortex pair. These mesoscale oceanographic structures can export coastal biological production up to 200 km offshore. We describe, based on the analysis of SeaWIFS ima...
