WP5 investigates how ice sheet meltwater discharge affects deep water formation, pole-to-pole connections, and large-scale ocean circulation, including the AMOC and ACC. This session combines new ocean observations, innovative analyses, and modelling approaches to better understand how freshwater influences the global climate system.
The programme begins with new observational results: the first sustained time series from the South Sandwich Trench and updated evidence of changes in South Atlantic water mass properties. We then move to data integration, with an analysis of “water mass archaeology” to trace the movement of water masses from the deep ocean to the surface. The final section focuses on modelling studies, highlighting the Southern Ocean’s response to Antarctic meltwater and the wider global impacts of freshwater forcing.
Date and time: October 7, 14:00-15:30 CEST
