Recent MODIS data from the Benguela Current region off the coast of Namibia include linear, yellowish features such as are shown in the above image collected on April 10, 2014. If any seafarer in the area knows what these are, we would also be curious to know. Perhaps these are associated with sulfur precipitation events that have been described in this area; perhaps these are phytoplankton blooms; perhaps there is some connection with the wind-borne dust seen in other parts of the larger image.
