Figure 5: Heatmaps with colour key and histogram of the monthly logarithmic mean abundances of a selection of phytoplankton species reported in the Belgian Phytoplankton Database (BPD).
From: Marine phytoplankton community composition data from the Belgian part of the North Sea, 1968–2010
Colours indicate the monthly mean logarithmic density (log10 cells L−1) of the species. a: Records dating from 1968 to 1978, b: Records dating from 1994 to 2010.
