Sediment cores from the Exmouth Plateau, Perth Basin, and Ceduna Terrace provide paleoceanographic records since the Last Glacial Maximum, roughly 20,000 years ago. Data includes sediment accumulation rates, biogenic components, benthic foraminiferal abundances, and stable isotopes. The dataset was collected by the Australian Geological Survey Organisation and is hosted by the Australian Ocean Data Network.
Use Cases
- Modeling changes in surface ocean productivity based on sediment accumulation rates and biogenic component data.
- Reconstructing intermediate and deep water chemistry based on benthic foraminiferal stable isotope records.
- Comparing glacial and Holocene ocean conditions based on authigenic uranium concentrations and benthic foraminiferal abundances.
Strengths
- Data from 14 sediment cores across two distinct regions of the Australian continental margin.
- Provides quantitative comparisons, such as glacial sediment accumulation rates being 1.5-2 times higher than Holocene rates.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
