Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201706. The data covers Repeat Hydrography Sections P09 and P10 in the North Pacific Ocean from July 19 to September 7, 2017. The dataset is provided by the National Oceanic and Atmospheric Administration.
Use Cases
- Modeling ocean acidification based on pH and dissolved inorganic carbon measurements
- Analyzing nutrient distribution and its impact on marine ecosystems based on nutrient profiles
- Studying water column properties and ocean circulation based on temperature and salinity profiles
- Investigating the relationship between dissolved oxygen and carbon chemistry in the North Pacific
Strengths
- Includes multiple key oceanographic parameters: DIC, alkalinity, pH, temperature, salinity, oxygen, and nutrients
- Data has a specific temporal coverage from 2017-07-19 to 2017-09-07
- Geographic focus is defined as the North Pacific Ocean on Repeat Hydrography Sections P09 and P10
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Description metadata is limited; actual data quality requires manual inspection after download
