Relative fall of Holocene sea level and coastal progradation, northeastern Spencer Gulf, S

Geoscience Australia Data provides measurements of intertidal environments and Holocene coastal complexes in northeast Spencer Gulf. The dataset includes precise elevation measurements of beach ridges and sea-grass deposits, along with 14C dating of mollusc shells and other materials to construct a sea-level history from 6000 years B.P. to the present. It was last updated on 2026-04-20.

Use Cases

• Modeling Holocene sea-level curves based on dated elevation indicators.
• Analyzing coastal progradation rates based on the chronology of beach ridge formation.
• Investigating regional tectonic uplift based on the correlation between high seismicity and relative sea-level fall.
• Calibrating paleoenvironmental reconstructions using dated facies like beach ridges and subtidal sea-grass deposits.

Strengths

• Elevation measurements are precisely referenced to the Australian Height Datum (AHD).
• Chronology is established using 14C dating on multiple material types (mollusc shells, sea-grass fibers).
• Sea-level history is constructed with event resolution for specific millennia (e.g., 6000-4000 years B.P.).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data files are in PDF and HTML formats, which may require extraction for computational analysis.
