From May to September 2015, chemical and physical oceanographic data were collected during two cruises (TXS15 and TXF15) on the M/V Tiglax in the Gulf of Alaska. The dataset includes measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, and nutrients. Data collection was funded by NPRB, NOAA, AOOS, and EVOSTC, and analysis was performed by the University of Alaska Fairbanks.
Use Cases
- Modeling ocean acidification impacts based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing seasonal nutrient dynamics based on nitrate, nitrite, phosphate, and silicate concentrations.
- Studying water column structure based on temperature and salinity profiles from CTD casts.
- Assessing marine ecosystem health based on dissolved oxygen levels.
Strengths
- Data covers two distinct seasonal cruises (spring and fall) in 2015.
- Multiple funding and analysis institutions (NPRB, NOAA, AOOS, EVOSTC, UAF) indicate collaborative rigor.
- Parameters include key ocean acidification and nutrient cycle variables.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
