North Atlantic Ocean measurements of carbonyl sulfide, dimethyl sulfide (DMS), and ammonium concentrations collected during the Omex-M30_1 research cruise in September 1994. The dataset contains 235 carbonyl sulfide saturation measurements, 288 carbonyl sulfide concentration measurements, 208 DMS concentration measurements, and 56 ammonium concentration measurements. Data were gathered by researchers Viet Ulshofer, Otmar Flock, Guenther Uher, and Thomas Raabe for the SCIOPS organization.
Use Cases
- Analyze spatial patterns of dimethyl sulfide (DMS) concentration to model ocean-atmosphere sulfur flux.
- Correlate carbonyl sulfide saturation and concentration measurements with water column properties.
- Study ammonium concentration distribution as a nutrient tracer in the dissolved plus reactive particulate phase.
- Validate biogeochemical models of organosulfur compound cycling using the 1994 cruise's 787 total measurements.
Strengths
- 787 total chemical measurements across four distinct variables.
- Precise temporal (September 6-20, 1994) and spatial (+51N to +36N, +1E to -16W) coverage.
Limitations
- Small sample size for ammonium measurements (56 records).
- Data is from a single, two-week cruise, limiting temporal generalizability.
- No column-level metadata or sample data provided for detailed schema understanding.
Provenance
- Source
