IN2024_V01: Southern Ocean Atmospheric DMS and MeSH Measurements

Proton Transfer Reaction Mass Spectrometer data captures dimethyl sulfide and methanethiol concentrations in the Southern Ocean atmosphere. Measurements were taken during the RV Investigator voyage IN2024_V01 from 2 January to 5 March 2024, traveling from Hobart to Fremantle. These observations support studies of biogeochemical cycling and ocean-atmosphere climate interactions.

Use Cases

• Modeling marine sulfur emissions based on DMS and MeSH concentration data.
• Studying ocean-atmosphere interactions and climate feedbacks based on trace gas observations.
• Analyzing biogeochemical cycling in the Southern Ocean based on atmospheric gas measurements.

Strengths

• Data provides key observations of trace gases in the remote Southern Ocean atmosphere.
• Measurements were collected during a dedicated multidisciplinary research voyage from January to March 2024.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
