RV Investigator voyage IN2024_V01 collected measurements of dimethyl sulfide (DMS) and methanethiol (MeSH) using a Proton Transfer Reaction Time-of-Flight Mass Spectrometer (PTR-ToF-MS). The voyage, titled 'Multidisciplinary Investigations of the Southern Ocean (MISO)', took place from 2 January to 5 March 2024 (AEST), traveling from Hobart to Fremantle. These data provide key observations of trace gases in the Southern Ocean atmosphere.
Use Cases
- Modeling biogeochemical cycling based on dimethyl sulfide and methanethiol concentrations.
- Studying climate interactions based on trace gas observations in the Southern Ocean atmosphere.
- Analyzing ocean-atmosphere processes based on voyage data linking physics, biogeochemistry, plankton, aerosols, and clouds.
Strengths
- Data collected during a dedicated multidisciplinary voyage from Hobart to Fremantle.
- Specific time range provided: 2 January to 5 March 2024 (AEST).
- Focuses on key trace gases dimethyl sulfide (DMS) and methanethiol (MeSH).
