R/V Ryofu Maru III Cruise RF201710: Ocean Carbon and Acidification Measurements

NOAA collected discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients during the R/V Ryofu Maru III cruise RF201710 in the North Pacific Ocean. The data covers a one-month period from November 25 to December 24, 2017. Measurements are part of the Ocean Carbon and Acidification Data System (OCADS).

Use Cases

• Modeling ocean acidification dynamics based on DIC, alkalinity, and pH measurements.
• Analyzing nutrient-oxygen relationships in the water column based on discrete profile data.
• Studying seasonal carbon cycling in the North Pacific based on the November-December 2017 time frame.
• Calibrating continuous sensor data with discrete sample measurements of temperature and salinity.

Strengths

• Includes multiple co-located chemical and physical parameters (DIC, alkalinity, pH, nutrients, oxygen, temperature, salinity).
• Data is associated with a specific research cruise (RF201710) and EXPOCODE (49UP20171125), providing clear provenance.
• Temporal coverage is precisely defined from 2017-11-25 to 2017-12-24.

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.
