Particulate Organic Carbon in Antarctic Coastal Polynyas and Off-Shelf Sites

Australian Ocean Data Network provides data on particulate organic carbon concentration from Antarctic waters south of the Polar Front. The dataset comprises three files with measurements from CTD deployments, including optical POC, ammonium, and carbon-to-nitrogen ratios. The record was last updated on 2026-07-13.

Use Cases

• Modeling particulate organic carbon flux based on optical measurements and beam attenuation coefficients.
• Studying nutrient dynamics in Antarctic polynyas based on ammonium concentration data.
• Analyzing stoichiometry of marine organic matter based on measured POC to PON ratios.
• Mapping biogeochemical properties in the Southern Ocean based on station latitude and longitude.

Strengths

• Data is structured across three specific files with distinct measurement focuses.
• Includes geospatial coordinates (latitude and longitude) for station locations.
• Contains multiple related chemical and optical parameters like salinity, PAR, and beam attenuation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Freshness should be verified as the last update date is in the future (2026-07-13).
