Single-celled Phytoplankton are Behind the Great Calcite Belt Algal Bloom

Research published in the journal Biogeosciences examines the chemistry behind an annual algal bloom and the algae that cause it ─ tiny, single-celled photosynthesizers called coccolithophores that are neither plants nor bacteria. Their microscopic swarms, shown in this NASA satellite image, dominate the Great Calcite Belt, a ring around the Southern Ocean so large it can be seen from space.
