CARINA: Arctic Ocean Carbon and Hydrographic Profiles from 1997

CARINA/58AA19970225 is a dataset of discrete water sample and profile observations collected from the R/V Haakon Mosby in the North Greenland and Norwegian Seas from February 25 to March 24, 1997. It includes measurements for dissolved inorganic carbon, alkalinity, dissolved oxygen, nutrients, salinity, and temperature. The data were collected by Truls Johannessen of the Bjerknes Centre for Climate Research using CTD and bottle instruments as part of the international CARINA synthesis project.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing nutrient cycling and primary production based on nitrate, phosphate, and silicate data.
• Studying water mass properties and circulation based on salinity, temperature, and hydrostatic pressure profiles.
• Calibrating biogeochemical models using the internally consistent, quality-controlled CARINA data synthesis.

Strengths

• Data is part of the CARINA synthesis project, an international effort to produce an internally consistent dataset for biogeochemical investigations.
• Includes multiple key variables for carbon system studies: dissolved inorganic carbon, alkalinity, dissolved oxygen, and nutrients.
• Provides a specific temporal snapshot from a defined research cruise (CARINA/58AA19970225) in the Arctic region.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single cruise in 1997, representing a specific time and location.
