Quaternary sediment data from the Recherche Archipelago, collected by the Australian Ocean Data Network. The dataset includes surficial sediments, video, multibeam sonar data, cores, and shallow seismics to examine inner shelf evolution. Holocene deposits up to 7 meters thick are documented, dominated by fragments of calcareous algae, molluscs, and bryozoans.
Use Cases
- Model sediment accumulation patterns based on seismic profiles and preserved palaeo-shoreline features.
- Analyze the influence of oceanography and wave abrasion on sediment production.
- Study the role of granite islands as sheltering features for sediment accumulation.
- Compare modern cool-water carbonate environments with ancient geological deposits.
Strengths
- Includes multiple data types: surficial sediments, video, multibeam sonar, cores, and shallow seismics.
- Documents Holocene deposits up to 7 meters thick.
- Focuses on a recognized world's largest modern example of a high-energy, cool-water carbonate realm.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific archipelago study area.
