TXS12/TXF12: Gulf of Alaska Ocean Chemistry Profiles from 2012

From May to September 2012, discrete water samples were collected during two cruises along the Seward Line in the Gulf of Alaska. The dataset includes measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, nutrients, and Delta Oxygen-18. Data collection was funded by NPRB, NOAA, AOOS, and EVOSTC, with analysis performed by researchers at the University of Alaska Fairbanks.

Use Cases

• Modeling ocean acidification dynamics based on dissolved inorganic carbon and total alkalinity measurements
• Analyzing seasonal nutrient cycles based on nitrate, nitrite, phosphate, and silicate data
• Studying water column stratification based on temperature and salinity profiles
• Investigating biological productivity and respiration based on oxygen and Delta Oxygen-18 measurements

Strengths

• Data covers two distinct seasonal cruises (spring and fall) in 2012
• Multiple funding and institutional sources (NPRB, NOAA, AOOS, EVOSTC, UAF) indicate collaborative validation
• Includes a suite of core oceanographic variables (DIC, TA, nutrients, oxygen, temperature, salinity)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Freshness should be verified as the last metadata update is dated 2026-03-05
