Phytoplankton size-abundance spectra in a coastal embayment (Ría de Vigo, NW Iberia)

The data set include the phytoplankton cell abundance (cell/ml) and size distribution of cells ranging from 0.5 µm to 158 µm in equivalent spherical diameter. The data were obtained from surface samples collected in a central station (42°14.09'N, 8°47.18'W) of Ría de Vigo (NW Iberian peninsula) during weekly/monthly samplings in two time series: July 2001 - July 2002 and April 2021 - May 2022.
