As well, the record shows that more than 90 percent of the calcareous nannoplankton
species went extinct at that time, and that most life disappeared from the upper portions of the ocean for almost a half million years, an effect geochemists call the "Strangelove Ocean."
"At the Cretaceous-Paleogene boundary, 93 percent of the nannoplankton went extinct," said Timothy J.
"Nannoplankton are the base of the food chain in the ocean.
Because of its size, nannoplankton
was only quantified (cells/L).

and protozoan microzooplankton during the J60FS North Atlantic bloom experiment: 1919 and 1990.
Due to their microscopic size and the near-global distribution of many taxa, calcareous nannoplankton
have become very popular for solving various stratigraphic problems, and many studies have been devoted to that end.
