From May to July 2019, IODP Expedition 383 sailed in the Pacific sector of the Southern Ocean to drill sediment cores along the Chilean Margin and in the Central South Pacific. The main goal of the project is to study how the dynamics of the Southern Ocean and the Antarctic Circumpolar Current affect the global climate system. Gisela sailed as co-chief scientist, and lead together with Frank Lamy, a geologist at the Alfred Wegener Institute for Polar and Marine Research, the expedition. Jenny Middleton and Julia Gotschalk sailed as stratigraphic correlator and sedimentologist, respectively.
