Description
Approximately 7,000 years of relative sea-level history is recorded in the morphology and stratigraphy of a beach-ridge strandplain at Cowley Beach, northeastern Australia. The dataset, associated with a 2019 study in Marine Geology, likely contains elevation data from a fine-scale digital elevation model used to analyze 36 prominent beach ridges. It was used to model strandplain topographic patterns under stable and rising sea-level scenarios.
Use Cases
Reconstructing regional Holocene sea-level curves based on the elevation of preserved berm facies.
Modeling coastal morphological response to subtle sea-level changes (tens of cm over millennia) based on strandplain elevation patterns.
Calibrating glacio-hydroisostatic adjustment models in far-field sites using the recorded highstand at around 6,000 years BP.
Analyzing the frequency of tropical cyclone events over millennia based on the stratigraphic record of storm-surge deposits and erosional unconformities.
Strengths
Covers a long temporal span of approximately 7,000 years.
Focuses on a specific, well-studied coastal landform with 36 prominent beach ridges.
Elevation data is compared with and matches robust published coral sea-level indicator data.
The study models expected topographic patterns, providing a methodological framework for similar sites.
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 a single study site in tropical northeastern Australia.
