Recherche Archipelago Inner Shelf Carbonate Sediment Data from South-western Australia

The Australian Ocean Data Network provides data on cool-water carbonate environments in the Recherche Archipelago, western Great Australian Bight. Surficial sediments, video, multibeam sonar, cores, and shallow seismics were collected to examine Quaternary shelf evolution. The dataset includes Holocene deposits up to 7 meters thick dominated by calcareous algae, molluscs, and bryozoans.

Use Cases

• Modeling sediment accumulation patterns based on Holocene deposits up to 7 meters thick.
• Analyzing the influence of granite basement topography on sediment preservation based on seismic profiles and multibeam sonar data.
• Studying the composition of carbonate gravel lags based on data dominated by bivalve and rhodolith fragments.
• Investigating the sheltering effect of granitic outcrops on marine sediment aggradation over sea level cycles.

Strengths

• Includes multiple data types: surficial sediments, video, multibeam sonar, cores, and shallow seismics.
• Describes Holocene deposits up to 7 meters thick in specific areas.
• Focuses on the world's largest modern example of a high-energy, cool-water carbonate depositional realm.

Limitations

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