Temporal and Spatial Variations of Phytoplankton from Boeckella Lake (Hope Bay, Antarctic peninsula)
The main water body at Hope Bay, Boeckella Lake, was sampled at four sites for phytoplankton during summer 1991 to assess the influence of nutrients from nearby penguin rookeries on both phytoplankton density and composition. The site located at the base of the rookeries had total phosphorus values...
