October-December 1992 measurements of key oceanic compounds collected during the James Clark Ross 2 research cruise in the Southern Ocean. The dataset includes 58 DMSO, 79 DMSP, 58 DMS, 90 methane concentration, 89 methane saturation, 89 total inorganic carbon, and 202 ammonium concentration measurements. Data was gathered by researchers Sue Turner, Ian Joint, Peter Williams, and Micheal Whitehouse as part of the Biogeochemical Ocean Flux Study (BOFS).
Use Cases
- Correlate dimethylsulfide (DMS) concentration measurements with latitude and longitude to map marine sulfur compound distributions.
- Analyze methane saturation and concentration data to identify potential oceanic methane source regions.
- Model carbon dioxide dynamics using total inorganic carbon (TCO2) concentration measurements from the water column.
- Investigate relationships between ammonium (NH4) concentration and other nutrient or biological productivity indicators.
- Validate regional biogeochemical models using the coordinated dimethylsulfoxide (DMSO), dimethylsulfoniopropionate (DMSP), and DMS measurement profiles.
Strengths
- Multivariate chemical profiles with 665 total measurements across 7 distinct compound groups.
- Precise temporal coverage from 28 October to 17 December 1992.
- Specific spatial coverage in the Bellingshausen Sea, Southern Ocean (27°S to 70°S, 54°W to 86°W).
- Data collection methods are explicitly documented for each compound (e.g., gas chromatography, coulometry).
Limitations
- Sample size is limited, with fewer than 100 measurements for most individual compounds.
- Data is from a single cruise in 1992, offering only a temporal snapshot.
- Geographic scope is restricted to the Southern Ocean's Bellingshausen Sea region.
