Indian Ocean Hydrographic Profiles: Carbon, CFCs, and Nutrients from GO-SHIP I10

Discrete profile measurements of dissolved inorganic carbon, alkalinity, CFCs, and other oceanographic variables were collected during the R/V Mirai cruise MR15-05. The data were gathered under the Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) in the Indian Ocean from December 23, 2015, to January 8, 2016. The dataset is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC113) and sulfur hexafluoride (SF6) concentrations.
• Assessing marine biogeochemical cycles based on nutrient and dissolved organic carbon (DOC) profiles.
• Calibrating and validating oceanographic models with co-located temperature, salinity, and oxygen data.

Strengths

• Includes a multi-parameter suite of co-located measurements for carbon, tracers, and physical properties.
• Data collection is part of the standardized GO-SHIP program, suggesting consistent methodology.
• Specific temporal coverage from 2015-12-23 to 2016-01-08 is provided.

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 modeling.
• Data may reflect geographic bias inherent to the single cruise track in the Indian Ocean.
