Formation, Morphology and Preservation of High-energy Carbonate Lithofacies: Evolution of

Data collected by the Australian Ocean Data Network, last updated 2026-06-27, to study the evolution of a high-energy, cool-water carbonate inner shelf. The dataset includes surficial sediments, video, multibeam sonar data, cores, and shallow seismics from the Recherche Archipelago. It documents Holocene deposits up to 7 meters thick and Pleistocene erosional surfaces over granite basement.

Use Cases

• Modeling sediment accumulation patterns based on seismic profiles and core data mentioned in the description.
• Analyzing the composition of carbonate gravel lags based on described fragments of calcareous algae, molluscs, and bryozoans.
• Mapping seabed morphology and basement topography based on multibeam sonar and video data mentioned in the description.
• Studying the influence of granitic outcrops on sediment sheltering and cementation as described.

Strengths

• Includes multiple data types: surficial sediments, video, multibeam sonar, cores, and shallow seismics.
• Documents specific geological features such as Holocene deposits up to 7 meters thick and a coarse bivalve and rhodolith dominated gravel lag.
• Focuses on a recognized modern analogue for geologically ancient cool-water carbonate deposits.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update is dated 2026-06-27.
