Tasmanian Reef Abundance Surveys from 2006 Transects

Australian Ocean Data Network provides transect survey data from 2006, focusing on abalone densities in eastern inshore Tasmanian waters. Surveys covered at least 10 reefs in each of four coastal regions, including St Helens, Bicheno, Dunalley, and the Actaeons region. The dataset was last updated on 2026-04-18.

Use Cases

• Modeling abalone population density based on surveyed reef characteristics.
• Comparing biological and environmental conditions across four Tasmanian coastal regions.
• Analyzing habitat preferences of abalone in typical commercial fishing depths and habitats.

Strengths

• Survey data from 2006 provides a historical baseline for population studies.
• Covers at least 10 reefs in each of four distinct coastal regions.
• Focuses on depths and habitats typical of commercial abalone fishing.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing on specific Tasmanian sites.
