Sponge Biodiversity Survey for Oceanic Shoals Marine Reserve Management

Approximately 750 sponge specimens from the Oceanic Shoals Commonwealth Marine Reserve were assigned to 348 species, with only 18% being taxonomically described. The data, compiled from three marine surveys, was used to analyze relationships between sponge communities, geomorphic features, and environmental variables like depth and substrate hardness. This study by Przeslawski et al. was published in 2015 to inform marine reserve management strategies.

Use Cases

• Modeling sponge community structure based on environmental variables like depth and substrate hardness mentioned in the description
• Identifying biodiversity hotspots associated with specific raised geomorphic features like carbonate banks
• Assessing taxonomic completeness and discovery rates for marine sponge species in understudied regions
• Designing marine reserve monitoring strategies based on spatial patterns of species assemblages

Strengths

• Includes approximately 750 collected specimens, providing a substantial sample size for analysis
• Species-level inventory with 348 identified species, offering detailed taxonomic resolution
• Data linked to specific geomorphic features and environmental measurements like depth and slope

Limitations

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

Geoscience Australia Data

Collection Method

Species-level inventory compiled from three dedicated marine surveys to the reserve.

Freshness

Data reflects surveys analyzed for a 2015 publication; the 2026 update likely refers to metadata.

Geography

Oceanic Shoals Commonwealth Marine Reserve (CMR) in northern Australia, specifically the Sahul Shelf and Van Diemen Rise.
