South Pacific Ocean measurements of dissolved carbon dioxide were collected during the P21 research cruise from March to June 1994. Scientists Chris Winn and Catherine Goyet gathered the data as part of the World Ocean Circulation Experiment (WOCE). The cruise covered a longitudinal transect from 74.1°W to 179.4°W and latitudinal range from 14.3°S to 25.5°S.
Use Cases
- Analyzing spatial trends in pCO2 (partial pressure of carbon dioxide) across the 14.3°S to 25.5°S latitude gradient.
- Correlating carbon dioxide measurements with cruise date and time to study seasonal springtime variability in 1994.
- Mapping measurement locations using longitude (74.1°W to 179.4°W) and latitude to visualize the cruise track and data density.
- Calibrating contemporary ocean carbon models with historical in-situ pCO2 measurements from a defined time period.
Strengths
- Data provides a precise temporal snapshot from a 3-month continuous research cruise (27 March to 25 June 1994).
- Spatial coverage is well-defined across a major ocean basin (South Pacific, 14.3°S to 25.5°S, 74.1°W to 179.4°W).
- Data collection is attributed to specific scientists and a major international program (WOCE), enhancing traceability.
Limitations
- Dataset is over 30 years old, limiting its relevance for analyzing current ocean carbon states.
- The specific number of measurement stations, rows, and data columns is unknown, hindering assessment of granularity.
- Geographic scope is limited to a single spring season in a specific region of the South Pacific.
