Interseasonal variability of benthic diatoms communities within the Windmill Islands, Antarctica
Progress Code: completed Sediment samples were collected with an Eckamn grab from four locations within the Windmill Islands (Herring Island, O'Connor Island, Shannon Bay and Brown Bay). A weekly sampling program was performed over a 10 week period, however not all locations could be accessed e...
