Abstract

Priyadarshani, an oligotrophic lake in Schirmacher Oasis (Antarctica), was surveyed during the austral summers of 1984–85 and 1986–87 in limnological and benthic studies. Benthic microfauna included seven taxonomic groups, dominated numerically by protozoa, rotifera, nematoda, turbellaria, tardigrada, oligochaeta and mites. Faunal density was high in moss-associated sediments. A maximum water depth of 6.5 m was recorded at the centre of the lake. A thick layer (25–90 cm) of moss and algal communities covered the bottom sediments. The total volume of water was estimated to be 62 million m3 over the submerged area of 0·297 km2.
