Seawater oxygen isotopes as a tool for monitoring future meltwater from the Antarctic ice-sheet

H. Kim and A. Timmermann

This research by Hyuna Kim and Axel Timmermann explores the promising role of seawater oxygen isotopes in monitoring Antarctic ice-sheet freshwater discharge and its impact on sea level rise. With findings indicating that isotope signals can provide earlier warnings than traditional salinity measures, this study highlights the need for continuous δ¹⁸Osw measurements to safeguard against rapid ice-sheet loss.
