Short summary

New tephra layer and microsiliceous assemblages are identified. Sediment records are contextualized for the Sabrina Coast continental rise chronological and paleoclimatic context. Some in-depth studies on margin instabilities, tephrochronology, and biostratigraphic/paleoenvironmental and sedimentary evolution are suggested. We performed this study to implement knowledge on the Antarctic biochronostratigraphy and microsiliceous sedimentation and benefited from international-level collaboration.
