The Recherche Archipelago in the Great Australian Bight was examined to understand Quaternary shelf evolution. Surficial sediments, video, multibeam sonar data, cores, and shallow seismics were collected, revealing Holocene deposits up to 7 meters thick. The dataset was published by Geoscience Australia Data and was last updated on 2026-04-20.
Use Cases
- Modeling sediment accumulation patterns based on described Holocene deposits up to 7 meters thick.
- Analyzing the influence of granite basement topography on sediment preservation based on seismic and multibeam data.
- Studying the composition of carbonate gravel lags based on described bivalve, rhodolith, and bryozoan fragments.
- Investigating the sheltering effect of granitic outcrops on sediment aggradation as suggested by seismic profiles.
Strengths
- Includes multiple data types: surficial sediments, video, multibeam sonar, cores, and shallow seismics.
- Describes specific sediment thicknesses, such as Holocene deposits up to 7 meters thick.
- Focuses on a recognized 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.
- Description metadata is limited; actual data quality requires manual inspection after download.
