June 1995 data from the Challenger 119B research cruise contains 98 measurements of dimethyl sulphide (DMS) concentration in the North Sea water column. Measurements were made by researcher Angela Hatton as part of the Land Ocean Interaction Study (LOIS) and Rivers, Atmospheres and Coast Study (RACS). The dataset captures a specific two-week period of oceanic organosulfur compound observations.
Use Cases
- Analyze DMS concentration variations across the +53N to +56N, +2W to +2E sampling region.
- Model relationships between DMS levels and other contemporaneous oceanographic variables from the cruise.
- Use the 1995 DMS measurements as a baseline for studying long-term changes in North Sea sulfur emissions.
- Correlate DMS concentration data with spatial coordinates and time stamps from the cruise track.
Strengths
- 98 discrete DMS concentration measurements provide a specific snapshot.
- Clear temporal coverage from June 14 to June 28, 1995.
- Defined spatial coverage within the North Sea (+53N to +56N, +2W to +2E).
Limitations
- Small sample size of 98 measurements limits statistical power.
- Data is from a single two-week cruise, not a long-term time series.
- No information on accompanying water column properties (e.g., temperature, salinity) is provided in the description.
