Abstract
This data set consists of one TIFF image, one JPEG image, and 9 PDF Open File Maps of airborne VLF-EM ortho total field data covering most of the Cobequid Highlands in northern Nova Scotia and part of the TGI-2 project area.
Airborne geophysical data used to generate these images were supplied by the Geological Survey of Canada (GSC) - Geophysical Data Centre, 615 Booth St., Ottawa, Ontario, K1A 0E9. This high-resolution VLF-EM data was digitally acquired as part of the Parrsboro Survey (GSC Project #189).
The data used to produce this image is the de-corrugated measured total field response using the "Orthogonal" transmitter. The "Orthogonal" transmitter for GSC Project #189 is Cutler, Maine. Total field VLF-EM data provide a measure of the internal electrical character (i. e. resistivity / conductivity) of the underlying Quaternary and bedrock geology.
