Holocene Beach-Ridge Elevation Data From Cowley Beach Australia

Relative sea-level records are preserved in a beach-ridge strandplain at Cowley Beach in tropical northeastern Australia. The dataset includes a fine-scale digital elevation model of 36 prominent beach ridges formed over approximately 7,000 years. Research by Brooke et al. was published in Marine Geology in 2019.

Use Cases

• Correlate strandplain surface elevation patterns with published regional sea-level data to validate glacio-hydroisostatic models.
• Model strandplain topographic patterns under stable versus rising sea-level scenarios using elevation class frequencies.
• Analyze the sensitivity of berm facies elevation within beach ridges to subtle sea-level changes of tens of centimeters per millennium.
• Utilize the digital elevation model of the strandplain to examine beach ridge morphology for regional sea-level record reconstruction.

Strengths

• Covers a long-term coastal progradation record spanning approximately 7,000 years.
• Includes a fine-scale digital elevation model for detailed morphological analysis of 36 beach ridges.

Limitations

• Spatial coverage is limited to a single site at Cowley Beach, northeastern Australia.
• Specific row counts, column details, and data formats are not provided in the description.
