WOCE P11A: Southern Ocean Carbon and Hydrographic Profiles from 1993

Southern Ocean, Indian Ocean, South Pacific Ocean, and Tasman Sea data collected from the AURORA AUSTRALIS research vessel between April 4 and May 9, 1993. It includes dissolved inorganic carbon, dissolved oxygen, salinity, temperature, and nutrient measurements from discrete bottle samples and CTD profiles. The data were collected by researchers from the Commonwealth Scientific and Industrial Research Organization as part of the World Ocean Circulation Experiment's CO2 survey.

Use Cases

• Modeling ocean carbon sequestration based on dissolved inorganic carbon measurements.
• Analyzing water mass properties and circulation using temperature, salinity, and pressure profiles.
• Studying nutrient dynamics in polar oceans based on nitrate, phosphate, and silicate concentrations.
• Calibrating biogeochemical models with in-situ dissolved oxygen and hydrographic data.

Strengths

• Data collection is part of the major World Ocean Circulation Experiment (WOCE), a recognized climate research program.
• Includes multiple core oceanographic variables: dissolved inorganic carbon, oxygen, nutrients, temperature, and salinity.
• Covers a specific, well-documented research cruise (WOCE_P11A) over a 36-day period in 1993.

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 is from a single cruise in 1993; temporal and spatial coverage is limited.
