Coastal Ocean Carbon and Water Chemistry from the 2012 WCOA Cruise

Discrete sample and profile data collected from NOAA Ship Bell M. Shimada in the Northeast Pacific Ocean from September 4 to 17, 2012. The dataset includes measurements of dissolved inorganic carbon, total alkalinity, nutrients, chlorophyll A, and physical water properties. It was collected by researchers from NOAA's Pacific Marine Environmental Laboratory and Oregon State University as part of the WCOA2012 cruise.

Use Cases

• Modeling ocean acidification dynamics based on dissolved inorganic carbon and total alkalinity measurements.
• Analyzing nutrient-phytoplankton relationships based on nitrate, phosphate, silicate, and chlorophyll A data.
• Studying coastal water mass mixing and biogeochemistry based on concurrent salinity, temperature, and oxygen profiles.

Strengths

• Data includes multiple related chemical, biological, and physical variables measured concurrently.
• Specific collection dates (2012-09-04 to 2012-09-17) and geographic regions are documented.
• Principal investigators and their affiliated institutions are explicitly named in the metadata.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal bias from a single two-week cruise in September 2012.
