South Pacific Ocean Carbon and Hydrographic Profiles from the ROGER REVELLE, 1997-1998

The South Pacific Ocean was sampled during a 1997-1998 research cruise to collect discrete chemical and physical profile data. The dataset includes measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, and temperature from CTD and bottle instruments. It was collected by researchers from Duke University and the Rosenstiel School as part of the CLIVAR Repeat Hydrography Program.

Use Cases

• Modeling ocean acidification based on pH and dissolved inorganic carbon measurements.
• Studying nutrient cycling and primary production based on nitrate, phosphate, and silicate data.
• Analyzing water mass properties based on salinity, temperature, and hydrostatic pressure profiles.
• Investigating the marine carbon pump based on particulate and total organic carbon measurements.

Strengths

• Includes 16 distinct chemical and physical parameters, such as alkalinity, dissolved inorganic carbon, and multiple nutrients.
• Data collected during a dedicated research cruise (AESOPS RR_KIWI-7/Ross_Sea_33RR19971202) over a one-month period in 1997-1998.
• Part of the systematic CLIVAR Global Ocean Carbon and Repeat Hydrography Program for quantifying changes in ocean properties.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 1997-1998; temporal and spatial coverage is limited.
