Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, and nutrients were collected by NOAA during the R/V Ryofu Maru III cruise rf201202. The data covers a specific voyage in the North Pacific Ocean from March 6 to March 25, 2012. It is part of the Ocean Carbon and Acidification Data System (OCADS).
Use Cases
- Modeling ocean acidification trends based on pH and alkalinity measurements
- Studying marine carbon system dynamics based on dissolved inorganic carbon (DIC) data
- Analyzing nutrient distributions in relation to ocean chemistry based on nutrient measurements
- Calibrating oceanographic models using discrete profile temperature and salinity data
Strengths
- Data originates from a specific research cruise with a known EXPOCODE (49UP20120306)
- Includes multiple key ocean chemistry parameters (DIC, alkalinity, pH, nutrients)
- Temporal coverage is precisely defined from 2012-03-06 to 2012-03-25
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to a single cruise track
