A 1961 seismic refraction survey conducted at dam sites on the Mersey River. The survey was requested by the Hydro-Electric Commission of Tasmania and is documented by Geoscience Australia. Data is available in PDF and HTML formats.
Use Cases
- Assess subsurface rock structure for dam foundation stability based on seismic refraction methods.
- Model geological layers at a proposed hydroelectric dam site based on the survey description.
- Compare historical geophysical survey techniques with modern methods based on the 1961 date.
Strengths
- Documented by Geoscience Australia, a national geoscience organization.
- Provides historical context with a specific survey date of 1961.
- Focuses on a specific project location: the Walters Marsh dam sites on the Mersey River.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is historical; geological conditions may have changed since 1961.
