Special Issue on the Gulf of San Jorge (Patagonia, Argentina)

On the Cover: A high concentration of suspended particulate matter (SPM) in the Gulf of San Jorge near Cape Tres Puntas captured on August 31, 2015, in a MODIS Aqua true color (Bands 1, 4, and 3; 500 m resolution) satellite image. During periods when the SPM concentration is high in the water column, the coastal circulation can be identified through the spatial configuration of SPM. This satellite image reveals the coastal low-salinity/high SPM waters originating from the Strait of Magellan, Santa Cruz River, and Puerto Deseado Estuary flowing to the north and reaching the southern area of the gulf, where a physically and biologically important tidal front develops.
