468 measurements of oceanic organosulfur compounds, methane, carbon dioxide, and ammonium were collected during the Omex-M27_1 research cruise in the North Atlantic. The data was gathered by researchers including Viet Ulshofer, Otmar Flock, Robin Kerr, and Thomas Raabe. The cruise took place from December 29, 1993, to January 17, 1994.
Use Cases
- Analyze the relationship between carbonyl sulfide saturation and concentration measurements to study its oceanic production or consumption.
- Model the distribution of methane (CH4) concentration across the sampled transect to identify potential seafloor seepage sites.
- Correlate total inorganic carbon (TCO2) concentration with ammonium (NH4) concentration to investigate biogeochemical linkages in the water column.
- Use the spatial coordinates (+50N to +48N, +4E to +14E) to map the geographic distribution of the four measured chemical species.
Strengths
- Contains 468 discrete chemical measurements across five specific variables.
- Provides precise temporal (Dec 1993-Jan 1994) and spatial (+50N to +48N, +4E to +14E) coverage for the cruise track.
- Measurement methods are specified (e.g., gas chromatography, manometry, colormetric autoanalysis).
Limitations
- Sample size is limited to a single, short cruise covering a specific region and season.
- Data is over 30 years old, limiting its use for studying contemporary ocean conditions.
- The 35 concentration measurements for carbonyl sulfide are a smaller subset compared to its 120 saturation measurements.
Provenance
- Source
- Measurements by researchers Viet Ulshofer, Otmar Flock, Robin Kerr, and Thomas Raabe as part of the Ocean Margin EXchange (OMEX) programme.
- Collection Method
- In-situ sampling and analysis via gas chromatography, manometry, and colormetric autoanalysis during the research cruise.
