Abstract
    The autoprophic picoplankton consists of predominantly coccoid cyanobacteria that annually produce a single population peak in summer of 10'-106 cells ml'. The base population remains at approximately 103 cells ml' during the other seasons. The summer maximum develops parallel to the rising water temperatures, then decreases gradually into fall. Mean sub-pycnocline concentrations remained well below those above the pycnocline between May and November, but were slightly higher during the colder months (December through April). Seasonal spatial differences and annual variations in abundance were noted.
