Discrete chemical and physical oceanographic data were collected from the R/V Melville in the North Pacific Ocean and Philippine Sea between March 21 and May 1, 2013. The dataset includes measurements for dissolved inorganic carbon, total alkalinity, pH, dissolved oxygen, nutrients, and chlorofluorocarbons. Data were gathered by researchers from NOAA PMEL, Scripps Institution of Oceanography, and other institutions using CTD and bottle instruments as part of the GO-SHIP repeat hydrography program.
Use Cases
- Modeling ocean acidification impacts based on dissolved inorganic carbon, pH, and total alkalinity measurements.
- Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) and sulfur hexafluoride (SF6) tracer data.
- Studying marine biogeochemical cycles based on nitrate, nitrite, phosphate, silicate, and dissolved organic carbon concentrations.
- Calibrating and validating ocean carbon cycle models using the suite of co-located carbon system parameters.
Strengths
- Includes a wide suite of co-located carbon system parameters (DIC, TA, pH) and transient tracers (CFCs, SF6).
- Data collection is associated with the standardized GO-SHIP repeat hydrography program.
- Cruise details and principal investigators from NOAA PMEL and Scripps are explicitly documented.
Limitations
- 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.
- Data may reflect geographic and temporal bias inherent to a single 2013 cruise.
