Resumen
We describe the spatial structure and velocity fields of two SeaWiFS-derived chlorophyll squirts in the Chilean coast. Consecutive, daily, L1A images were rectified and analyzed by means of a geographic information system. The velocity fields were obtained through feature-tracking analysis (subjective method). Both the hammerhead shape and the spatial structure of the velocity field agree with previous conceptual models. We succinctly discuss the biological consequences of squirts for the Humboldt Current coastal ecosystem.
