Discrete oceanographic measurements from a 1994 research cruise in the North Greenland Sea capture dissolved inorganic carbon, alkalinity, and nutrient concentrations. Data were collected by scientists from the Commonwealth Scientific and Industrial Research Organization and others aboard the HAKON MOSBY vessel. This profile and sample data contributes to the CARINA and CLIVAR global carbon inventory programs.
Use Cases
- Calculate ocean acidification parameters like aragonite saturation state using DISSOLVED INORGANIC CARBON (DIC) and TOTAL ALKALINITY (TA) columns.
- Model vertical nutrient profiles and their relationship to water masses by analyzing NITRATE, PHOSPHATE, and SILICATE against HYDROSTATIC PRESSURE and Potential temperature (theta).
- Assess water column stratification and mixing processes by correlating SALINITY and WATER TEMPERATURE measurements with depth.
- Estimate biological oxygen consumption in the Arctic Ocean by examining DISSOLVED OXYGEN levels alongside nutrient data.
- Use the CTD and bottle instrument data to validate regional ocean circulation models for the North Greenland Sea.
Strengths
- Includes 11 key chemical and physical variables for carbon cycle analysis, such as DIC, TA, and nutrients.
- Data originates from a coordinated international program (CLIVAR/CARINA) ensuring standardized collection protocols.
Limitations
- Dataset is temporally limited to a single three-week cruise in February 1994, preventing analysis of seasonal or long-term trends.
- Spatial coverage is restricted to the specific track of the HAKON MOSBY in the North Greenland Sea.
