Gulf of Alaska Ocean Chemistry Profiles from 2011 Seward Line Cruises

Two research cruises (TXS11 and TXF11) collected discrete water samples in the Gulf of Alaska from 2011-05-06 to 2011-09 19. The dataset includes dissolved inorganic carbon, total alkalinity, temperature, salinity, oxygen, nutrients, and Delta Oxygen-18. Data were collected and analyzed by the University of Alaska Fairbanks and funded by multiple agencies including the North Pacific Research Board and NOAA.

Use Cases

• Modeling ocean acidification impacts based on dissolved inorganic carbon and total alkalinity measurements.
• Analyzing seasonal nutrient cycles (Nitrate, Nitrite, Phosphate, Silicate) in a coastal ecosystem.
• Studying water mass properties and mixing based on concurrent temperature, salinity, and oxygen profiles.
• Investigating freshwater inputs and water source tracing using Delta Oxygen-18 data.

Strengths

• Data covers two distinct seasonal cruises (Spring and Fall) in 2011.
• Multiple funding and analysis sources (UAF OARC, CFOS, Whitledge Lab) suggest collaborative quality control.
• Includes a suite of co-located chemical and physical parameters for multivariate analysis.

Limitations

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