North Pacific Ocean Carbon and Nutrient Profiles from 2014 Cruise

NOAA's dataset contains discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients from the R/V Ryofu Maru III cruise RF14-03. The data was collected in the North Pacific Ocean during a two-week expedition from April 11 to April 24, 2014.

Use Cases

• Model ocean acidification by analyzing correlations between dissolved inorganic carbon (DIC), total alkalinity, and pH on total scale.
• Assess water column biogeochemistry by examining nutrient concentrations alongside temperature and salinity profiles.
• Calibrate satellite-derived salinity or temperature data using in-situ discrete measurement profiles.
• Study seasonal carbon cycling in the North Pacific Ocean using time-series data from the 2014 cruise.

Strengths

• Data covers multiple key ocean carbon system variables: DIC, total alkalinity, pH, oxygen, and nutrients.
• Measurements are from a specific, documented research cruise (EXPOCODE 49UP20140411) providing traceable provenance.
• Temporal coverage is precisely defined for a two-week period in April 2014.

Limitations

• The dataset represents a single cruise's snapshot, limiting spatial and temporal generalizability for the North Pacific.
• Data format is listed as HTML, which is non-standard for analytical use and may require significant parsing.
• Sample data and row/column counts are unavailable, preventing immediate assessment of dataset scale and structure.
