Characterization of a small eutrophic Antarctic lake (Otero Lake, Cierva Point) on the basis of algal assemblages and water chemistry
Otero Lake is the main water body of Cierva Point, Danco Coast (SSSI No. 15). During the 1992/1993 and 1994/1995 seasons, abiotic parameters and the structure and dynamics of the phytoplankton were studied. Algal assemblages from the phytoplankton, from algal clumps encased in the lake ice and from...
