Southern and Indian Ocean Hydrographic Profiles with Carbon Chemistry, 2019

Southern and Indian Ocean discrete profile measurements collected during the R/V Thomas G. Thompson cruise GO-SHIP_I06S from 2019-04-03 to 2019-05 14. The dataset includes dissolved inorganic carbon, total alkalinity, pH, chlorofluorocarbons, temperature, salinity, dissolved oxygen, and nutrients. This U.S. GO-SHIP I6S 2019 section is a repeat of earlier transects from 2008 and 1996.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and total alkalinity measurements.
• Tracing water mass age and circulation patterns based on chlorofluorocarbon (CFC11, CFC12) concentrations.
• Analyzing biogeochemical relationships based on concurrent nutrient, oxygen, temperature, and salinity profiles.
• Assessing decadal change in ocean properties by comparing this 2019 section with earlier 2008 and 1996 transects.

Strengths

• Includes a suite of co-located hydrographic and chemical variables for integrated analysis.
• Covers a specific time range from 2019-04-03 to 2019-05-14 during a dedicated research cruise.
• Represents a repeated transect, enabling temporal change analysis against 2008 and 1996 data.

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 and temporal bias inherent to a single ship track.
