North Greenland and Norwegian Seas water column measurements from a 1997 research cruise. The dataset includes dissolved inorganic carbon, alkalinity, nutrients, oxygen, salinity, and temperature collected via CTD and bottle sampling. Data were collected by Truls Johannessen of the University of Bergen as part of the CARINA synthesis project.
Use Cases
- Calculate seawater pH and pCO2 from ALKALINITY and DISSOLVED INORGANIC CARBON measurements to study ocean acidification.
- Analyze correlations between NITRATE, PHOSPHATE, SILICATE, and DISSOLVED OXYGEN to investigate nutrient cycling and biological productivity.
- Model water mass properties and circulation using profiles of Potential temperature (theta), SALINITY, and HYDROSTATIC PRESSURE.
- Validate satellite-derived sea surface salinity or ocean color products with in-situ SALINITY and nutrient data from discrete samples.
Strengths
- Includes key carbon system variables (ALKALINITY, DISSOLVED INORGANIC CARBON) essential for acidification studies.
- Data contributed to the CARINA international synthesis project, implying quality control and internal consistency checks.
Limitations
- Temporal coverage is limited to a single cruise over one month in 1997.
- Geographic scope is restricted to specific stations in the North Greenland and Norwegian Seas.
- Sample size is unknown but likely limited to discrete bottle casts from one vessel.
