CLIVAR I05 2009: Indian Ocean Carbon and Hydrographic Measurements from 2009

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, temperature, salinity, and other oceanographic variables were collected during the R/V Roger Revelle cruise CLIVAR_I05_2009 in the Indian Ocean from 2009-03-20 to 2009-05 15. The data were collected by researchers from NOAA AOML, PMEL, Scripps Institution of Oceanography, and RSMAS as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Quantifying changes in ocean carbon storage based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing ocean circulation and ventilation timescales based on chlorofluorocarbon (CFC) and sulfur hexafluoride (SF6) tracer data.
• Studying ocean biogeochemistry and nutrient cycling based on dissolved oxygen, nitrate, and phosphate measurements.
• Calibrating and validating ocean carbon cycle models using the suite of directly observed hydrographic parameters.

Strengths

• Includes a multi-parameter suite of carbon system and hydrographic variables collected during a dedicated research cruise.
• Data collection is associated with the systematic, global CLIVAR Repeat Hydrography Program.
• Principal investigators are listed from multiple authoritative oceanographic institutions (NOAA AOML/PMEL, Scripps, RSMAS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
