TXS13/TXF13: Gulf of Alaska Ocean Chemistry Profiles from 2013

Gulf of Alaska chemical and physical data from discrete samples and CTD profiles collected during the M/V Tiglax Seward Line cruises TXS13 and TXF13 from April to September 2013. The dataset includes 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 the Ocean Acidification Research Center and Whitledge Laboratory at the University of Alaska Fairbanks.

Use Cases

• Model ocean acidification impacts based on dissolved inorganic carbon and total alkalinity measurements.
• Analyze seasonal nutrient cycles based on nitrate, nitrite, phosphate, and silicate data.
• Study water column stratification based on temperature and salinity profiles.
• Correlate oxygen levels with biological activity based on oxygen and Delta Oxygen-18 data.
• Validate regional oceanographic models based on discrete chemical and physical measurements.

Strengths

• Data covers two distinct seasonal cruises (Spring TXS13 and Fall TXF13) in 2013.
• Includes multiple key oceanographic parameters: DIC, TA, nutrients, temperature, salinity, and oxygen.
• Analysis was performed by specialized laboratories (OARC and Whitledge Laboratory) at the University of Alaska Fairbanks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
