INTERANNUAL VARIATION IN DOMINANT PHYTOPLANKTON SPECIES AND BIOMASS NEAR DAVIS STATION, EAST ANTARCTICA (18th Symposium on Polar Biology)
Phytoplankton biomass and speciation were monitored at an inshore site near Davis Station, East Antarctica (68°35'S, 77°58'E) during three consecutive summer seasons (December-February, 1992-5). Four distinct phytoplankton assemblages were identified in which the dominant species were: Pha...
