Summary: The scope of this study is fully embedded within the ANDRILL (ANarctic geological DRILLing) Project objectives to improve understanding of Antarctica's role in Cenozoic global climatic changes. Despite the key role that Antarctica plays in today's climate, our understanding of this continent is still at its infancy with respect to other areas of the globe. Particularly debated is the middle and late Miocene when the continent underwent a significant climate change from a climatic optimum (MMCO) to a glacial phase. Diatom biostratigraphy has played a key role so far in reconstructing Antarctic climate history. The contribution of this research to this discipline is addressed in three separate manuscripts, mainly articulated as chronostratigraphic and taxonomic improvements within the latest early to middle Miocene.
