The CLIVAR_I06S_2008 dataset includes discrete sample and profile data collected by NOAA AOML, Scripps SIO, and UCSB researchers during the R/V Roger Revelle cruise along CLIVAR Repeat Section I06S from 2008-02-04 to 2008-03-17. Measurements include dissolved inorganic carbon, total alkalinity, pH, CTD temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons, tritium, and stable isotopes. These data support the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program's mission to quantify changes in heat, freshwater, and carbon dioxide storage and transport.
Use Cases
- Quantifying changes in ocean carbon storage based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing ocean circulation and mixing patterns based on CTD temperature, salinity, and dissolved oxygen profiles.
- Studying anthropogenic tracer distribution based on chlorofluorocarbon (CFC-11, CFC-12, CFC113) data.
- Investigating water mass age and ventilation based on tritium, helium, and neon measurements.
- Calibrating and validating ocean carbon cycle models based on the suite of carbonate system parameters.
Strengths
- Data collected during a dedicated research cruise (EXPOCODE 33RR20080204) over a specific time range (2008-02-04 to 2008-03-17).
- Includes a wide suite of carbonate system parameters (DIC, alkalinity, pH, pCO2) and complementary hydrographic and tracer measurements.
- Produced by authoritative institutions (NOAA AOML, Scripps SIO, UCSB) as part of the international CLIVAR Repeat Hydrography Program.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
