Transient Electromagnetics, Passive Seismic, and Borehole Electromagnetics, Gamma, and Nuclear Magnetic Resonance Methods to Characterize Glacial Sediments in East Falmouth, Massachusetts, Near Nantucket Sound
In March 2016, the U.S. Geological Survey drilled a borehole, MA-FSW-750, through the unconsolidated sediments and 1.5 m into the bedrock in East Falmouth, Massachusetts, to improve understanding of the glacial history and hydrologic properties of the Cape Cod aquifer. Polyvinyl casing was set through the overburden and into the bedrock. About 10 days after borehole MA-FSW-750 was drilled, it was logged with geophysical methods including natural gamma radiation and electromagnetic induction (EMI) logs to identify changes in the lithology and fluid properties of the subsurface. In addition, the gamma and EMI logs were collected about 100 days after drilling, which allowed the drilling fluids to be displaced and natural sediments to collapse around the casing.
These data are served in the USGS borehole log archiver database GeoLogLocator (add link).
