IN2024_V01: Southern Ocean Atmospheric Trace Gas Measurements from RV Investigator Voyage

Southern Ocean atmospheric measurements of dimethyl sulfide (DMS) and methanethiol (MeSH) acquired during the RV Investigator voyage IN2024_V01 from 2 January to 5 March 2024, Hobart to Fremantle. Data were collected using a Proton Transfer Reaction Time-of-Flight Mass Spectrometer (PTR-ToF-MS) and aggregated by the Australian Ocean Data Network. The dataset supports studies of biogeochemical cycling and climate interactions in the Southern Ocean region.

Use Cases

• Modeling marine sulfur emissions and their climatic impact based on dimethyl sulfide (DMS) measurements.
• Studying biogeochemical cycling in the Southern Ocean based on trace gas observations.
• Investigating ocean-atmosphere interaction processes based on concurrent gas and voyage data.
• Analyzing temporal and spatial trends of methanethiol (MeSH) in a remote marine environment.

Strengths

• Focuses on key trace gases (DMS and MeSH) relevant to climate and biogeochemistry.
• Data collected during a dedicated multidisciplinary research voyage (IN2024_V01) from January to March 2024.
• Measurements made with a specific, sensitive instrument (Proton Transfer Reaction Time-of-Flight Mass Spectrometer).

Limitations

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