Abstract Seventy-five diatom taxa were identified from net plankton samples collected inshore during winter, spring and summer 1977–8 near Davis Station, East Antarctica. Species richness was found to be higher in winter than in summer; this is the first time this trend has been reported in antarctic coastal regions. When these taxa were grouped according to the general habitats in which they normally occur, the benthic assemblages dominated the planktonic ones. Of the plankton, most species were of oceanic origin in winter and late summer and are thought to have been swept inshore by a cyclonic gyre which is known to occur in summer but has not been studied in winter.
