117 measurements of dimethyl sulphide and dimethylsulphoniopropionate, alongside hundreds of methane, nitrous oxide, and halocarbon readings, were collected during the DI234 research cruise. The data was gathered by scientists Sue Turner, Peter Liss, Rob Upstill-Goddard, Jon Baker, and Wendy Broadgate for the ACSOE project. The cruise took place in the North-East Atlantic from June 6 to July 9, 1998.
Use Cases
- Analyze the correlation between oceanic DMS concentration and atmospheric methane saturation to study marine sulfur emissions.
- Model the spatial distribution of nitrous oxide concentration in the water column across the +54N to +63N latitude range.
- Compare the concentration of bromomethane in the dissolved phase with isoprene measurements to investigate marine halogen production.
- Calculate the saturation levels of methane and nitrous oxide from their measured concentrations for gas flux estimations.
Strengths
- Provides 117 concurrent measurements of DMS and DMSP, enabling paired analysis.
- Includes 298 measurements of methane concentration in the water column, offering detailed vertical or spatial profiles.
- Covers a specific geographic region (+54N to +63N, +15W to +23W) during a defined 34-day period in 1998.
Limitations
- Sample sizes vary significantly between compounds, with only 63 measurements for bromomethane.
- Data is from a single cruise in 1998, limiting temporal generalizability and representing a historical snapshot.
- The raw description lists multiple measurement methods (e.g., different DMS techniques), which may complicate direct comparisons.
