Australian East Coast Sea Level Changes from Sand Deposits and Dune Morphology, 1948-1950

A geological investigation of beach-sand heavy-mineral deposits along the Australian east coast from the Clarence River to North Stradbroke Island. The work was conducted by the Bureau of Mineral Resources between 1948 and 1950, involving detailed boring and sampling of beaches, coastal dunes, and plains. Results pertaining to changing sea levels are summarized in the publication.

Use Cases

• Analyzing historical sea level changes based on described borehole levels relative to high water mark.
• Studying coastal sediment composition and morphology based on the investigation of heavy-mineral deposits.
• Reconstructing past coastal environments based on the analysis of dune and coastal plain samples.

Strengths

• Investigation conducted over a defined multi-year period from 1948 to 1950.
• Covers a specific geographic region from northern New South Wales to southern Queensland.
• Includes detailed field methods such as boring and sampling up to several miles inland.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
