Phytoplankton bloom

This phytoplankton bloom (lower left corner) within the
nutrient-rich, upwelled waters of the Benguela Current (coast of
Namibia; 19.5S, 11.5E) is quite bright and is typical of the
species Emiliania huxleyi, which is reported to bloom in older
upwelled waters that have been depleted somewhat in nutrients by
other species of phytoplankton. Blooms of E. huxleyi appear
bright, milky white due to the production of large quantities of
particulate calcium carbonate. The internal waves impinging on
the coast can also be seen. This photograph is unusual because
it shows both features in sunglint (internal waves) and differ-
ences in water color (phytoplankton bloom). (S36-82-077)
