North Pacific Ocean water chemistry profiles collected during the R/V Keifu Maru II cruise KS09-01 from 2009-01-16 to 2009-03-04. The dataset includes discrete measurements of dissolved inorganic carbon, pH, temperature, salinity, oxygen, and nutrients. It was collected by the National Oceanic and Atmospheric Administration and is part of the GO-SHIP program.
Use Cases
- Model ocean acidification trends based on pH and dissolved inorganic carbon measurements
- Analyze nutrient distribution and its impact on marine ecosystems based on nutrient data
- Study ocean ventilation and oxygen dynamics based on oxygen concentration profiles
- Correlate physical water properties with chemical parameters based on temperature and salinity data
Strengths
- Includes multiple key ocean chemistry parameters: DIC, pH, oxygen, nutrients, temperature, and salinity
- Data is part of the standardized GO-SHIP international repeat hydrography program
- Cruise has a specific temporal coverage from January to March 2009
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
