Identification to the level of taxa was made via light microscopy from known
volumes in settling chambers.

Sampling Description.

C= counted number of cells in all counting fields
Ae= effective filter area (mm2)
n= number of fields analyzed
v= sample volume corrected for preservative addition
As= area of counting filed (mm2)
Biomass is based on geometric formulas,
e.g., sphere volume V= p/6 x d3
cylinder V= p/4 x d2 x l
ellipsoid V= p/6 x l x a x b
(see reference)
carbon biomass is calculated from volume biomass, where
C= phytoplankton carbon (ug l-1 C)
B= phytoplankton biomass (ug l-1 wet mass)
Cyanophytes C= B x 0.22
Thecate dinoflagellates C= B x 0.13
Diatoms C= B x 0.11
