Alt Tag: Sea surface density, September 2011.Map Description:
Global map of sea surface density for September 2011. This map is derived from Aquarius sea surface salinity and ancillary sea surface temperature using TEOS-10 equation of state. In these maps, yellow regions have the higher density and pink regions have lower density.
Seawater density is determined by its temperature and salinity. Surface seawater temperature varies widely over the globe (-1°C to 30°C). Credit: NASA.
