Trophic Markers of Southern Ocean Marine Predators from Biological Samples

Stable isotope, fatty acid, and diet data were collected from multiple predator species in the Southern Ocean by the Australian Ocean Data Network. The data originates from biological samples including blood, blubber, feathers, and whiskers. The dataset was last updated on 2026-07-13.

Use Cases

• Modeling marine food web structure based on stable isotope data mentioned in the description
• Analyzing predator dietary composition based on fatty acid profiles mentioned in the description
• Tracking seasonal or individual variation in predator diet based on sample types (blood, feathers, whiskers) mentioned in the description

Strengths

• Data includes multiple trophic markers (stable isotopes, fatty acids, diet) for a holistic view.
• Samples were collected from diverse biological tissues (blood, blubber, feathers, whiskers).
• Dataset is hosted by the authoritative Australian Ocean Data Network.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
