Pan-Atlantic connectivity of marine biogeochemical and ecological processes and the impact of anthropogenic pressures. Status Conference Research Vessels 2024, MARUM, the Center for Marine Environmental Sciences, University of Bremen, Germany pp. 473-482. International audience The transit of R/V SONNE from Las Palmas (11.12.2021) to Guayaquil, Ecuador (11.01.2022) was directly related to the international collaborative project SO287-CONNECT of GEOMAR in cooperation with Hereon and the University of Bremen, supported by the German Federal Ministry of Education and Research (BMBF) between October 2021 and January 2024. The research expedition was conducted to decipher the coupling of biogeochemical and ecological processes and their influence on atmospheric chemistry. A comprehensive work program combined continuous underway water and atmospheric sampling and measurements, incubations, as well as 36 stations from the upwelling zones off Africa into the Sargasso Sea and further to the Caribbean and the equatorial Pacific.WATER MASS ANALYSIS ALONG THE NORTH EQUATORIAL CURRENTWith the Extended Multi-parameter analysis (OMP) from Karstensen & Tomczak (1998) with source water types (SWT) based on Liu & Tanhua (2021), eight upper and lower Antarctic Intermediate and Mediterranean Water, as well as North Atlantic Deep Waters, Antarctic Bottom and Northeast Atlantic Bottom Water were analysed in the Atlantic transect. Based on a literature search, it was possible to additionally identify North Atlantic Subtropical Mode water and ...
