NOAA NCEI Accession 0191354 contains surface underway measurements of carbon dioxide partial pressure, salinity, and temperature. Data were collected from the small boat Kilo Kai in Kaneohe Bay, Hawaii, within the North Pacific Ocean. Observations span from June 13, 2013, to July 17, 2014.
Use Cases
- Calculate air-sea CO2 flux using partial pressure of carbon dioxide in water and air, barometric pressure, and sea surface temperature.
- Analyze seasonal variability in coastal carbon chemistry by correlating sea surface salinity and temperature with water pCO2 over the 13-month time series.
- Calibrate or validate autonomous CO2 measurement systems using data from the shower head chamber equilibrator and CO2 gas analyzer.
- Investigate local biogeochemical processes in Kaneohe Bay by examining the relationship between sea surface temperature and partial pressure of carbon dioxide in water.
Strengths
- Data collection spans over 13 months from 2013-06-13 to 2014-07-17, providing seasonal coverage.
- Includes key variables for carbon flux calculation: partial pressure of CO2 in both water and air, barometric pressure, salinity, and temperature.
Limitations
- Sample size and spatial extent are limited to surface underway tracks from a single small boat in Kaneohe Bay.
- Unknown row count and data density prevent assessment of temporal resolution or completeness.
