Horizontal-to-Vertical Spectral Ratio (HVSR) Soundings and Depth-to-Bedrock Data for the Owasco Inlet Watershed, Cayuga and Tompkins Counties, New York 2016 In 2016, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected horizontal-to-vertical seismic soundings at 31 locations in the Owasco Inlet valley, Cayuga and Tompkins Counties, New York to help determine thickness of the unconsolidated deposits. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and others, 2013). The passive-seismic method uses a single, broad-band three-component (two horizontal and one vertical) seismometer to record ambient seismic noise. In areas that have a strong acoustic contrast between...

Potentiometric surfaces are interpolated for the shallow and deep parts of the aquifer, and rasters of the potentiometric surfaces are included in this data release. Wells were classified as being screened in the shallow or deep parts of the aquifer based on station name (some wells have a layer identifier in the station name) or, if no indication of aquifer layer was given in the station name, based on the depth of the well; wells with depths less than 80 feet below land surface were classified as shallow and wells with depths of 80 feet or deeper were classified as deep.

Efficiency also varies substantially in response to variable hydraulic conductivity.
