Thousands of still images from the Eastern and Western margins of Australia were used to identify and characterise deep-sea lebensspuren. The Australian Ocean Data Network compiled these features into a Lebensspuren Directory. The data was used to correlate abiotic factors to lebensspuren and evaluate the technique's utility for quantifying biological activity.
Use Cases
- Correlate abiotic environmental factors with biological activity based on lebensspuren features
- Evaluate the use of high-resolution still photography for quantifying biodiversity in deep-sea soft sediments
- Characterize biological communities over larger areas compared to traditional grab and boxcore sampling
- Identify and catalog sedimentary structures produced by infaunal organisms from underwater imagery
Strengths
- Thousands of still images provide a broad spatial characterization
- Focus on lebensspuren addresses the challenge of sampling small and infaunal deep-sea animals
- Data covers both the Eastern and Western margins of Australia
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 bias inherent to the Australian margins
