North Pacific Ocean Carbon and Acidification Measurements from R/V Keifu Maru II, 2016

Discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients were collected during the R/V Keifu Maru II cruise ks201608 in the North Pacific Ocean. The National Oceanic and Atmospheric Administration (NOAA) gathered this data from 2016-09-17 to 2016-10-07. The dataset is part of the Ocean Carbon and Acidification Data System (OCADS).

Use Cases

• Modeling ocean acidification impacts based on pH and dissolved inorganic carbon measurements.
• Analyzing relationships between nutrients and biological productivity based on nutrient concentration data.
• Studying water mass properties and circulation based on temperature and salinity profiles.
• Calibrating and validating satellite-derived ocean carbon data based on in-situ discrete measurements.

Strengths

• Measurements include key ocean carbon system parameters (DIC, alkalinity, pH) for acidification studies.
• Data is associated with a specific research cruise (ks201608) with a defined time range (2016-09-17 to 2016-10-07).
• Dataset is managed by the authoritative NOAA Ocean Carbon and Acidification Data System (OCADS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single cruise in the North Pacific.
