393 discrete measurements of dimethyl sulfide concentration were collected from the North Atlantic water column during a 17-day research cruise in July 1995. The data was gathered by the SCIOPS organization using filtration, purging, cryogenic trapping, and gas chromatography techniques. This dataset captures a specific snapshot of oceanic organosulfur compounds from the OMEX expedition.
Use Cases
- Analyze dimethyl sulfide concentration variations across the spatial range of +51 to +39 latitude and -3 to -16 longitude.
- Correlate measurement values with cruise date and location to study short-term temporal and spatial patterns in July 1995.
- Use the 393 concentration measurements as a baseline for modeling oceanic dimethyl sulfide emissions in the North Atlantic.
Strengths
- 393 discrete concentration measurements provide a substantive sample for analysis.
- Precise spatial (+51 to +39 latitude, -3 to -16 longitude) and temporal (July 14-30, 1995) boundaries are documented.
Limitations
- Dataset is small with only 393 data points, limiting statistical power for complex models.
- Data is temporally stale, representing a single two-week period from 1995 with no recent updates.
- No column details or sample data are available to assess data structure or unit consistency.
