Data of cell size, cell carbon content, and biomass of dinoflagellates and diatoms in the oceanic ecosystem of the Southern Gulf of Mexico

Greatest linear dimension (GLD, µm) measurements as a proxy of the cell
size, cell carbon estimates (pgC cell-1), and carbon biomass assessments
of dinoflagellates and diatoms cells are reported in this dataset. The
phytoplankton samples were collected from the oceanic regions, Perdido and
Coatzacoalcos, located in the Southern Gulf of Mexico. The information
comes from four campaigns carried out during 2016 (MF1 cruise, late
winter, and MF2 cruise, late summer), 2018 (MF3 cruise, spring), and 2019
(MF4 cruise, spring). The carbon data (pg C cell-1) were based on
biovolume calculations derived from linear dimension measurements of
individual cells and the approximate geometric body shape of each genus.
The biomass assessments (µg C L-1) were performed using these carbon
content factors and cell abundances.
