Holocene Beach-Ridge Strandplain Elevation Data from Northeastern Australia

36 prominent beach ridges at Cowley Beach record coastal progradation over approximately 7,000 years. The dataset contains elevation patterns from a fine-scale digital elevation model, analyzed against regional Holocene sea-level history. It was compiled by researchers including Brendan P. Brooke and published in Marine Geology in 2019.

Use Cases

• Model strandplain topographic patterns under stable versus continually rising Holocene sea-levels using elevation class frequencies.
• Compare the elevation of berm facies from the strandplain with published coral sea-level indicator data to validate regional records.
• Analyze the sensitivity of beach ridge berm facies elevation to subtle sea-level changes of tens of centimeters over millennia.
• Examine the relationship between beach ridge morphology and glacio-hydroisostatically driven coastal elevation change during the Holocene.

Strengths

• Data is derived from a series of 36 prominent beach ridges, providing a clear morphological sequence.
• Temporal coverage spans approximately 7,000 years of Holocene coastal history.
• Analysis is grounded in peer-reviewed research published in Marine Geology with a specific DOI.

Limitations

• The dataset appears to be a published study summary; raw tabular data or the digital elevation model may not be directly accessible.
• Spatial coverage is limited to a single site at Cowley Beach in tropical northeastern Australia.
• Sample size and specific data dimensions (rows, columns) are unknown from the provided description.
