%X 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 images, a squirt located in the northern chilean coast (30¡ã s). our results show that the spatial structure of the velocity field, and the hammerhead shape, agree with previous conceptual models. we used the circulation data, resulting from feature-tracking analysis, to estimate the offshore export of coastal carbon production. we conclude that squirts represent a net carbon exporting mechanism accounting for 5% to 12% of coastal carbon production
