Surface underway measurements of carbon dioxide partial pressure, salinity, sea surface temperature, and barometric pressure were collected aboard the WAKATAKA MARU in the North Pacific Ocean. The dataset covers an 8-day voyage from June 5 to June 12, 2014. Data collection was led by researchers from the National Research Institute of Fisheries Science and the Tohoku Regional Fisheries Research Laboratory.
Use Cases
- Calculate air-sea CO2 flux using the partial pressure of carbon dioxide in water and barometric pressure measurements.
- Analyze the relationship between sea surface temperature and salinity with carbon dioxide fugacity to study oceanic drivers of CO2 solubility.
- Validate regional ocean carbon cycle models by comparing modeled pCO2 values against the in-situ partial pressure (or fugacity) of carbon dioxide - water data.
- Correlate meteorological conditions, via barometric pressure time-series, with short-term variability in surface ocean chemistry.
Strengths
- Data includes direct, co-located measurements of four key variables: pCO2, salinity, SST, and barometric pressure.
- Measurements are temporally resolved as surface underway data, capturing spatial gradients during the cruise.
- Collection follows a standardized protocol using a Carbon dioxide (CO2) gas analyzer and other shipboard instruments.
Limitations
- Dataset is limited to a single 8-day cruise, providing a snapshot rather than long-term temporal coverage.
- Spatial coverage is confined to the specific track of the WAKATAKA MARU in the North Pacific during the cruise period.
- The sample size (number of data rows) and data resolution (temporal or spatial) are not specified in the provided metadata.
