Description
Sediment core data from the Last Glacial Maximum (roughly 20,000 years ago) to the Holocene, collected by the Australian Geological Survey Organisation from the Exmouth Plateau, Perth Basin, and Ceduna Terrace. The dataset provides evidence of changes in surface ocean productivity and intermediate/deep water chemistry in the southeastern Indian Ocean and Great Australian Bight. It includes measurements of sediment accumulation rates, biogenic components, benthic foraminiferal abundances, and stable isotopes.
Use Cases
Modeling glacial-interglacial changes in surface ocean productivity based on sediment accumulation rates and biogenic component data.
Reconstructing past intermediate and deep water chemistry based on benthic foraminiferal stable isotope records.
Comparing glacial productivity and carbon isotope profiles between different ocean basins based on the described regional findings.
Strengths
Data from 14 sediment cores (7 from the Exmouth Plateau/Perth Basin and 7 from the Ceduna Terrace) provides regional coverage.
Quantifies specific glacial-Holocene contrasts, such as sediment accumulation rates being 1.5-2 times higher during the Last Glacial Maximum.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is delivered in PDF and HTML formats, which may require extraction for computational analysis.
Provenance
Source
Australian Geological Survey Organisation, aggregated by the Australian Ocean Data Network.
Collection Method
Collection and analysis of sediment cores from the Australian continental margin.
Time Range
Covers the Last Glacial Maximum (roughly 20,000 years ago) to the Holocene.
