Australian Ocean Data Network provides Proton Transfer Reaction Mass Spectrometer data from the RV Investigator voyage IN2024_V01. The dataset contains measurements of dimethyl sulfide (DMS) and methanethiol (MeSH) in the Southern Ocean atmosphere, collected from 2 January to 5 March 2024 (AEST) between Hobart and Fremantle. These observations support studies of biogeochemical cycling and ocean-atmosphere climate interactions.
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 provides key observations of trace gases in the Southern Ocean atmosphere.
- Measurements were acquired during a specific voyage (IN2024_V01) from 2 January to 5 March 2024.
- Dataset is hosted by the Australian Ocean Data Network, a recognized ocean data aggregator.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- File formats are PNG and HTML, suggesting the primary data may be visualizations or reports rather than raw tabular data.
