Coccolithophore and diatom cell abundance from the upper mixed later of the Great Calcite Belt, January- February 2011 in the South Atlantic Ocean and February-March 2012 in the South Indian Ocean

This data was collected as part of the Great Calcite Belt project, from 60W to 120E and 30S to 60S. during MV1101 onboard R/V Melville, January- February 2011 in the South Atlantic Ocean and RR1202 onboard the R/V Roger Revelle, February-March 2012 in the South Indian Ocean. Samples for biomineralizing phytoplankton community structure were taken from the upper 30 m of the water column. This data consists of coccolithophore and diatom cell abundances.
