Coastal Carbon Measurements from NOAA Ship David Starr Jordan, 2006

Surface underway data from NOAA Ship David Starr Jordan, collected between August 6 and December 7, 2006, in the Gulf of California and North Pacific Ocean. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure, collected using carbon dioxide gas analyzers and thermosalinographs. It is part of the Global Coastal Carbon Data Project, focusing on carbon cycle dynamics in coastal regions and continental margins.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Analyzing coastal carbon cycle dynamics using underway surface measurements.
• Calibrating or validating satellite-derived sea surface temperature and salinity products.
• Studying seasonal variability in coastal ocean carbonate chemistry during the 2006 cruise period.

Strengths

• Data covers a specific four-month research cruise (2006-08-06 to 2006-12-07) with precise temporal bounds.
• Includes direct measurements of carbon dioxide partial pressure in both air and water, a key variable for flux calculations.
• Dataset is part of a curated, multi-source project (Global Coastal Carbon Data Project) focused on coastal carbon.

Limitations

• Column names and exact data structure are not provided in any source, limiting immediate usability.
• Conflicting metadata: last update dates are reported as both 2006-12-07 and 2026-03-05.
• No information on data volume (rows, size) or licensing terms is available.
