SOCCOM_096U20160314_UW: Surface Underway Carbon Dioxide Measurements

From March 14 to April 15, 2016, the RV Investigator collected surface underway data across the Indian Ocean, South Pacific Ocean, and Tasman Sea. The dataset contains measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, wind speed, and barometric pressure. These observations were gathered by CSIRO researchers as part of the SOCCOM project to study air-sea gas exchange.

Use Cases

• Calculating air-sea CO2 flux based on the difference between atmospheric and seawater partial pressure.
• Analyzing correlations between sea surface temperature, salinity, and carbon dioxide concentrations.
• Validating and calibrating biogeochemical models for the Southern Ocean using in-situ underway data.
• Studying meteorological conditions (wind speed, barometric pressure) alongside chemical oceanographic variables.

Strengths

• Data collection covers a specific, well-documented research voyage (cruise ID 096U20160314) over a one-month period.
• Includes directly measured, co-located variables essential for carbon flux calculation (fCO2 in air and water, wind speed).
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating vetting and persistence.

Limitations

• Key metadata is missing or conflicting: row count, file size, and specific column names are not provided by any source.
• The most recent update date is inconsistent across entries (2016-04-15 vs. 2026-03-06), creating uncertainty about maintenance.
• Documentation is sparse, with no explicit license, which may restrict clear reuse.
