LATE QUATERNARY CLIMATE VARIATIONS IN WEST ANTARCTICA AND THEIR IMPACT ON THE MARINE SILICEOUS MICROALGAE
Main objective is the reconstruction of late Quaternary climatic events in the northern and north-western parts of the Antarctic Peninsula shelf based on species variation, abundance and ecological structure of diatom complex in bottom sediments. Methods: siliceous microalgae were used as biomarkers...
