Spring and fall 2009 data from the Gulf of Alaska includes dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, and nutrients (Nitrate, Nitrite, Phosphate, Silicate). The dataset was collected during two cruises (TXS09 and TXF09) from May to September 2009. It was funded by NPRB, NOAA, AOOS, and EVOSTC, with analysis by the Ocean Acidification Research Center and Whitledge Laboratory at the University of Alaska Fairbanks.
Use Cases
- Modeling ocean acidification impacts based on dissolved inorganic carbon and total alkalinity measurements
- Analyzing seasonal nutrient cycles (Nitrate, Nitrite, Phosphate, Silicate) in the Gulf of Alaska
- Studying water column properties based on CTD-derived temperature, salinity, and oxygen profiles
- Investigating carbon system variability in coastal marine ecosystems
Strengths
- Includes multiple key ocean chemistry parameters (DIC, TA, nutrients, oxygen)
- Data covers two distinct seasons (spring and fall) within 2009
- Analysis performed by specialized university laboratories (OARC-UAF, Whitledge Lab)
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
