Over 1,500 bottle cast profiles collected by Duke University and other institutions aboard the NATHANIEL B. PALMER and ROGER REVELLE research vessels. Measurements include temperature, salinity, and nutrients from the Antarctic and South Pacific. Data collection spanned from September 1996 to March 1998 under the JGOFS/AESOPS project.
Use Cases
- Analyzing temperature and salinity profiles to study vertical water column structure and identify thermoclines.
- Correlating nutrient measurements with temperature data to investigate Antarctic primary productivity.
- Mapping spatial and temporal variations in salinity across the Southern Ocean from discrete bottle samples.
- Using cast location and time data to track oceanographic conditions during the JGOFS/AESOPS process study.
Strengths
- Data collected over 19 months from September 1996 to March 1998.
- Profiles sourced from two dedicated research vessels, NATHANIEL B. PALMER and ROGER REVELLE.
- Project supported by the coordinated JGOFS/AESOPS scientific study.
Limitations
- Data is over 25 years old, limiting analysis of recent oceanographic changes.
- Discrete bottle casts provide point-in-time measurements, not continuous monitoring.
- Specific row count, column details, and sample resolution are unknown.
