Deep Sea Lebensspuren: Biological Features on Australian Seafloor Margins

Geoscience Australia Data compiled a directory of deep-sea lebensspuren from thousands of high-resolution still images taken along the Eastern and Western margins of Australia. The data was used to correlate abiotic factors with biological features and to evaluate the technique's utility for quantifying biological activity and diversity in soft-sediment habitats. The dataset was last updated on 2026-05-14.

Use Cases

• Correlating abiotic environmental factors with biological activity based on lebensspuren features.
• Evaluating still image analysis as a technique for quantifying biodiversity in deep-sea soft sediments.
• Characterizing biological communities over large areas of the seafloor based on imagery.

Strengths

• Thousands of still images provide a broad spatial characterization of seafloor habitats.
• Focuses on lebensspuren features, which are indicators of biological activity in infaunal-dominated soft sediments.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
