Surface underway measurements of carbon dioxide partial pressure, salinity, and sea surface temperature collected during four NOAA research cruises in the Pacific Ocean from July to December 2006. The data were collected by the Pacific Marine Environmental Laboratory using barometric pressure sensors, CO2 gas analyzers, and thermosalinographs. This dataset is part of the Global Coastal Carbon Data Project, focusing on carbon cycle dynamics on continental margins.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure differences mentioned in the description.
- Analyzing coastal carbon cycle dynamics based on underway measurements from continental margins.
- Calibrating satellite-derived sea surface temperature and salinity products based on in-situ sensor data.
- Studying temporal variability in oceanic pCO2 based on time-series data from research cruises.
Strengths
- Data collected during four distinct research cruises (M20601-M20604) over a five-month period.
- Includes multiple related variables: carbon dioxide partial pressure in air and water, salinity, sea surface temperature, and barometric pressure.
- Collected by a recognized oceanographic laboratory (NOAA PMEL) as part of a defined project (Global Coastal Carbon Data Project).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2006-12-02 00:00:00; freshness should be verified.
