Observational records from Southern Ocean have revealed significant natural system, linked to large-scale modes of tectonic evolution, ocean circulation, diverse ecosystems, and changes in ice sheet and sea ice. However, it remains one of the least observed regions on Earth, with limited spatial coverage and very few records extending beyond the instrumental period. The session aims to highlight a range of geology, petrology, geophysics, paleo-oceanography, geochemistry, marine biology, environmental science, and ocean dynamics on multi spatial-temporal scales. We are interested in engaging the wider community to allow participation and inclusion through effective partnerships to ensure sustainable observations in Southern Ocean.
