Discrete and profile measurements of dissolved inorganic carbon, alkalinity, temperature, salinity, and pressure collected aboard the HEALY research vessel in the Arctic Ocean and Beaufort Sea from September 7 to 27, 2010. The data were collected by NOAA PMEL and University of Alaska researchers as part of the CLIVAR_HLY1003 cruise to quantify changes in ocean heat, freshwater, and carbon dioxide storage. This dataset contributes to the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon (DIC) and total alkalinity (TA) measurements.
- Analyzing Arctic water column structure based on hydrostatic pressure, salinity, and temperature profiles.
- Studying ocean acidification trends in polar seas based on carbonate system parameters.
- Calibrating regional biogeochemical models based on discrete sample data from a specific cruise.
Strengths
- Data collected over a focused 20-day period in September 2010.
- Includes key carbonate system parameters (DIC and TA) alongside core physical variables.
- Associated with a specific research cruise (HLY1003) and program (CLIVAR).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to a single cruise track in the Arctic Ocean and Beaufort Sea.
