Methanethiol and dimethyl sulfide measurements in seawater and the atmosphere around the Antarctic Peninsula and in the Weddell Sea

Charel Wohl, Leah Ruby Williams, Elisabeth Deschaseaux, Lauriane L. J. Quéléver et autres

Inclusion of methanethiol (MeSH) in global atmospheric chemistry–climate model assessments has shown that MeSH emissions increase SO 2 , particulate sulfate and aerosol cooling over the Southern Ocean. However, measurements in the Southern Ocean are sparse. In February and March 2023, we …

S1 Seawater Vocus PTR operationTo monitor instrument performance and drift, the seawater-sampling Vocus PTR was calibrated at least daily using a 10 multi-compound gas standard (nominal concentration 500 nmol mol -1 ; methanol, acetaldehyde, acetone, isoprene, DMS, benzene, toluene, m-xylene, α-pinene in …

A closed‐loop system for the semi‐continuous measurement of biogenic volatile organic compounds from marine organisms

Jasmine B. Haskell, Elisabeth Deschaseaux, Erin Dunne, Hilton B. Swan et autres

Abstract The marine environment constitutes a significant source of Biogenic Volatile Organic Compounds (BVOCs) to the atmosphere with impacts on ecosystem functioning, atmospheric particle formation, carbon cycling and climate. However, processes governing BVOC emissions remain largely unconstrained due to their large spatial …
