Measurements of Methanethiol (MeSH) and dimethyl sulfide (DMS) in surface seawater during POLAR-CHANGE Antarctic expedition 2023 on board the BIO Hesperides C. Wohl https://doi.org/10.5281/zenodo.12758981
Short summary
Methanethiol and dimethyl sulfide are precursors to aerosols which cool the climate. Here we present measurements of these compounds in surface seawater and ambient air around the Antarctic Peninsula and in the Weddell Sea, highlighting that a large fraction of volatile sulfur emissions from the ocean is biogenic methanethiol. This dataset presents some of the factors driving the variability of these compounds.
