Southern Ocean Carbon Chemistry and Hydrographic Profiles from 1992-1993

CARINA/49ZS19921203 and JARE34 datasets include biological, chemical, and physical profile data from the SHIRASE research vessel. The data cover the Indian Ocean, South Pacific Ocean, and Tasman Sea from December 1992 to March 1993. Naoki Sato and Masao Ishii collected measurements for dissolved inorganic carbon, oxygen, nutrients, chlorophyll, and hydrographic variables using CTD and bottle instruments.

Use Cases

• Modeling ocean carbon uptake based on dissolved inorganic carbon and pH measurements
• Analyzing nutrient cycles and primary productivity based on nitrate, phosphate, silicate, and chlorophyll data
• Studying water mass properties and circulation based on salinity, temperature, and hydrostatic pressure profiles

Strengths

• Data is part of the CARINA international synthesis project for internally consistent biogeochemical investigations
• Includes 14 distinct measured variables including carbon system parameters and nutrients
• Covers a specific three-month cruise across multiple ocean basins

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic/temporal bias inherent to a single research cruise
