Cruise 096U20150321: Surface Ocean Carbon and Meteorological Measurements

Southern Ocean, South Pacific Ocean, and Tasman Sea surface underway data were collected from the RV Investigator between March 21 and 29, 2015. Measurements include the partial pressure of carbon dioxide in air and water, sea surface temperature, salinity, barometric pressure, and wind speed and direction. These data were collected by researchers from the Commonwealth Scientific and Industrial Research Organization (CSIRO) as part of the SOCCOM project.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differential measurements.
• Analyzing ocean carbon uptake variability using continuous surface underway pCO2 data.
• Correlating sea surface temperature and salinity with carbon dioxide fugacity.
• Studying Southern Ocean meteorological conditions via wind speed and barometric pressure records.

Strengths

• Data covers a specific, well-documented research cruise (096U20150321) in a critical ocean region.
• Includes directly measured chemical (CO2), physical (SST, salinity), and meteorological (wind, pressure) variables.
• Cross-platform presence on NASA Earthdata and Data.gov signals established provenance and importance.

Limitations

• Column names and exact data structure are unknown, hindering precise analysis.
• Key metadata such as row count, file size, and specific license are missing from all sources.
• Data is from a single, short cruise in 2015, limiting temporal and spatial scope.
