January to March 2024 measurements of dimethyl sulfide (DMS) and methanethiol (MeSH) in the Southern Ocean atmosphere, collected via Proton Transfer Reaction Time-of-Flight Mass Spectrometer (PTR-ToF-MS). The data were gathered during the RV Investigator voyage IN2024_V01 from Hobart to Fremantle, supporting studies of biogeochemical cycling and ocean-atmosphere processes. The dataset is hosted by the Australian Ocean Data Network.
Use Cases
- Modeling marine sulfur cycling based on dimethyl sulfide (DMS) concentration data.
- Studying ocean-atmosphere gas exchange processes based on trace gas measurements.
- Investigating climate interactions and aerosol formation based on atmospheric DMS and MeSH observations.
- Analyzing spatial and temporal trends of trace gases in the Southern Ocean based on the voyage track.
Strengths
- Data covers a specific voyage from 2 January to 5 March 2024.
- Focuses on key trace gases (DMS and MeSH) relevant to biogeochemical cycling.
- Collected using a Proton Transfer Reaction Time-of-Flight Mass Spectrometer (PTR-ToF-MS), suggesting high-resolution measurements.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to a single research voyage.
