Flagellates and "monads" were dominant in the plankton, except two days in December, when diatoms were prevalent. Thalassiosira untarctica and a few species of the genera Nilzschia and Chaeloceros were the major diatoms during the summer. Several other diatoms. Corethron criophilum. Eucampia bulaustium. and Rhizosolenia spp. together with the all-summer dominants, contributed to the diatom peak in December, following the breaking of ice. Algal peaks always followed periods of calm days and stable atmospheric pressure; the increased stability of the water column at such times appears to be the factor determining the onset of the periods of phytoplankton maxima. Decline of algal peaks could be largely attributed to grazing by Euphausia superba and E. crystallorophias.}, type={Article}, title={Periodicity and composition of summer phytoplankton in Ezcurra Inlet, Admiralty Bay, King Geojge Island, South Shetland Islands}, URL={http://www.journals.pan.pl/Content/111573/PDF-MASTER/1981_3-4_055-070.pdf}, keywords={Antarctic, phytoplankton, periodicity}, }
