Surface chemical, meteorological, and physical data collected by Saildrone TPOS_2017_SD1005 in the North and Tropical Pacific Ocean from September 2 to December 1, 2017. The dataset includes measurements of partial pressure of carbon dioxide in water and atmosphere, mole fractions of CO2, barometric pressure, oxygen saturation, and pH. These data were collected by NOAA NCEI using instruments including a CO2 gas analyzer, humidity sensor, oxygen meter, and thermosalinographs.
Use Cases
- Calculate ocean carbon uptake based on the difference between seawater and atmospheric pCO2.
- Analyze seasonal carbon dioxide variability in the Pacific Ocean based on time-series pCO2 measurements.
- Correlate atmospheric conditions with surface ocean chemistry based on barometric pressure and humidity sensor data.
- Model ocean acidification trends based on pH measurements on the total scale.
- Validate satellite-derived ocean carbon estimates based on in-situ surface pCO2 data.
Strengths
- Data includes multiple related parameters (pCO2, pH, oxygen saturation) for integrated analysis.
- Collection period spans three months (2017-09-02 to 2017-12-01), providing a continuous time series.
- Data originates from a specific, documented Saildrone mission (TPOS_2017_SD1005) in the North and Tropical Pacific Ocean.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last updated 2017-12-01 00:00:00; freshness should be verified.
