The dataset from the R/V Ryofu Maru III cruise rf201109 includes discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients in the North Pacific Ocean. It was collected by the National Oceanic and Atmospheric Administration from September 12 to September 29, 2011. The data is part of the Ocean Carbon and Acidification Data System.
Use Cases
- Modeling ocean acidification processes based on dissolved inorganic carbon and pH measurements
- Analyzing marine nutrient cycles based on nutrient concentration data
- Studying water column properties based on temperature and salinity profiles
- Assessing ocean carbon uptake based on total alkalinity measurements
- Investigating marine oxygen dynamics based on oxygen measurements
Strengths
- Data covers a specific 18-day cruise in September 2011, providing a focused temporal snapshot
- Includes multiple key ocean chemistry parameters (DIC, alkalinity, pH, nutrients, oxygen)
- Profile measurements likely provide vertical distribution data through the water column
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 in the North Pacific Ocean
