Surface underway chemical and physical data collected aboard NOAA Ship KA'IMIMOANA during five cruises in 2007. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure. Data were collected by researchers from the NOAA Pacific Marine Environmental Laboratory using gas analyzers, equilibrators, and thermosalinographs.
Use Cases
- Calculate air-sea CO2 flux based on the difference in partial pressure between the atmosphere and water.
- Analyze spatial patterns of ocean carbon chemistry across the North and South Pacific Ocean.
- Correlate sea surface temperature with carbon dioxide solubility based on concurrent measurements.
- Validate or calibrate ocean carbon cycle models using in-situ surface underway observations.
Strengths
- Data covers a specific time series from March to October 2007 across two major ocean basins.
- Includes directly measured, concurrent variables critical for carbon flux calculation (pCO2 in air and water, SST, salinity).
- Collected by a recognized research institution (NOAA PMEL) using standard instrumentation.
Limitations
- Last updated 2007-10-25; freshness should be verified for contemporary applications.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
