Confirmed Karst Cavities in Limestone — 300 MHz GPR Profiles to 4 m Depth
Description
Raw GPR profiles acquired over limestone containing confirmed karst cavities, using a GSSI UtilityScan DF dual-frequency antenna. The 300 MHz channel is the useful one here: it delivers a clear signal down to 3.5–4 m and images the dissolution voids together with the bedrock interface. The simultaneously recorded 800 MHz channel covers the shallow weathered zone and lets you compare both frequencies over the same targets.
This dataset provides an interpretation reference that synthetic or unvalidated data cannot offer. Unprocessed .DZT files, suitable for karst interpretation training, void-detection algorithm testing, and frequency comparison.
