SOS-iClimate: Southern Ocean Salinity-Isotopic Fingerprints and Impacts on Global Climate
The Young Investigator Group SOS-iClimate seeks an answer to the question how melting Antarctic ice masses alter the ocean salinity and circulation and if these changes will amplify or dampen global warming in the future. For this purpose, we will identify and quantify the causes of past and future salinity changes in the Southern Ocean using ocean tracers, in particular seawater isotopes. These tracers serve as a fingerprint of impact of rapidly melting ice masses on the ocean’s salinity and we will use them to constrain a climate model.
