Image Caption:
Coastal upwelling along the coastal boundary of the Benguela
Current (Coast of Namibia; 27.5S, 14.5E)

The cold upwelled water is adjacent to the coastline and extends
about 65 km (35 n.mi.) offshore. The cold water stabilizes the
atmospheric boundary layer and results in a smoother water sur-
face, relative to the roughened, offshore water. In the sunglint
pattern, the smoother, upwelled water reflects sunlight more like
a mirror, concentrating the sunglint to a smaller area. Outside
the bright central disc, the sunglint highlights internal waves
which are refracting around submarine topography. (S36-73-094)
