CARINA/18SN19970831 data includes chemical and physical oceanographic measurements collected from the LOUIS S. ST. LAURENT in the Beaufort Sea and Northwest Passage from August 31 to September 16, 1997. The data set contains variables such as dissolved inorganic carbon, alkalinity, chlorofluorocarbons, salinity, and water temperature, collected using CTD and bottle instruments. It was compiled by researchers from Bedford Institute of Oceanography, CSIRO, Institute of Ocean Sciences, and Oregon State University as part of the international CARINA synthesis project.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
- Tracking historical chlorofluorocarbon (CFC) distributions as ocean tracers based on CFC-11, CFC-12, and CFC-113 data.
- Analyzing water column structure and oceanographic conditions based on temperature, salinity, and hydrostatic pressure profiles.
- Investigating Arctic Ocean biogeochemical processes for climate studies based on the CARINA project's synthesized data.
Strengths
- Data originates from a specific research cruise (CARINA/18SN19970831) with a defined time range (1997-08-31 to 1997-09-16).
- Includes multiple key variables for carbon system studies: alkalinity, dissolved inorganic carbon, and three chlorofluorocarbon species.
- Data collection involved multiple institutions, suggesting a collaborative and standardized approach.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 1997-09-16; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
