Chemical and physical oceanographic data collected during two M/V Tiglax Seward Line cruises in the Gulf of Alaska in 2014. The dataset includes measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, nutrients, and Delta Oxygen-18 from discrete samples and CTD profiles. Data were collected and analyzed by the University of Alaska Fairbanks and funded by multiple agencies including NOAA and the North Pacific Research Board.
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 structure based on temperature and salinity profiles
- Investigating biological productivity based on oxygen and Delta Oxygen-18 measurements
Strengths
- Data covers two distinct seasonal cruises (Spring TXS14 and Fall TXF14) in 2014
- Multiple funding and analysis sources (NOAA, NPRB, UAF OARC, Whitledge Lab) suggest collaborative quality control
- Includes a suite of key 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
- Data may reflect geographic and temporal bias inherent to the two specific cruises
