In 1979 two areas of upwelling were observed off Somalia, one near 10°N and one near 5°N. The areas of upwelling were characterized by sea surface temperatures between 17° and 22°C, high concentrations of surface nutrients (5 to 20 micromoles of nitrate per liter) and surface chlorophyll a (0.4 to 5.0 milligrams per cubic meter), primary productivity averaging 1.7 grams of carbon per square meter per day, and a phytoplankton assemblage dominated numerically by the diatom Nitzschia delicatissima.
