Neil C Terry, PhD
Neil C Terry, PhD is a a research hydrologist at the USGS New York Water Science Center.
I am a research hydrologist at the USGS New York Water Science Center, where I specialize in near-surface geophysics, modeling, and water-related projects. Particular focus areas include groundwater quality monitoring, hydrogeological characterization, contaminant detection, and groundwater-surface water interactions. I also lead and support software/methods development efforts, specifically focusing on linking electrical geophysical measurements with soil and hydrogeological properties.
Prior to joining the USGS, my PhD work at Rutgers University centered around hydrogeophysical approaches to characterize and study processes occurring in wetlands - particularly carbon gas cycling in peatlands. During this time, I also participated in critical zone characterization and archaeological studies, among other projects. My MS work at the University at Buffalo primarily involved linking geophysical data to soil moisture distributions through coupled geophysical and unsaturated flow models in a Bayesian framework.

Selected borehole geophysical logs from three contaminant sites in California, Wisconsin, and New Jersey Selected borehole geophysical logs from three contaminant sites in California, Wisconsin, and New Jersey
Borehole geophysical logs were collected to characterize bedrock aquifers at three contamination sites located in California, Wisconsin, and New Jersey. The data were collected by the U.S. Geological Survey (USGS) and the University of Guelph from 2014 to 2015 as part of the U.S. Department of Defense Strategic Environmental Research and Development Program (SERDP) and Environmental...
Depth to bedrock determined from passive seismic measurements, Neversink River watershed, NY (USA) Depth to bedrock determined from passive seismic measurements, Neversink River watershed, NY (USA)
This data release documents streambed sediment thickness in the Neversink watershed (NY) as determined by field observations and HVSR passive seismic measurements, and were collected as an extension of a previous data set collected in the same watershed (see Associated Items). These measurements were made between May 17, 2021 and May 21, 2021 using MOHO Tromino three-component...
Data used to estimate groundwater salinity above the Montebello oil field (California, USA) Data used to estimate groundwater salinity above the Montebello oil field (California, USA)
This release contains borehole geophysical electrical log data (elogs), total dissolved solids sample data (TDS), and geostatistical program files used to estimate the salinity distribution in groundwater above and in the vicinity of the Montebello Oil Field, located near Los Angeles, California, USA. Original data are drawn from a variety of publicly available sources and are combined...
Near-surface geophysical data collected along French Gulch near Breckenridge, Colorado, USA, September 2020 Near-surface geophysical data collected along French Gulch near Breckenridge, Colorado, USA, September 2020
Near-surface geophysical surveys were completed in September 2020 in a mine-affected drainage near Breckenridge, Colorado, known as French Gulch. The study area was along a 0.3 mile (0.5 kilometer [km]) reach of French Gulch, approximately 2 river miles upstream from its confluence with the Blue River. This data release presents data from three geophysical surveys that used fiber-optic...
Geophysical Data Collected for an Assessment of a Proposed Landfill Site in Fredericktown, Missouri, June 2018 Geophysical Data Collected for an Assessment of a Proposed Landfill Site in Fredericktown, Missouri, June 2018
In June 2018, the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA) collected geophysical measurements to help evaluate the suitability of a proposed landfill site for disposing mine-waste materials in Fredericktown, Missouri. Geophysical methods were used to evaluate and characterize the unconsolidated sediment (i.e., regolith) above the...
Surface Geophysical data collected along Blacktail Creek in June 2017 near Williston, North Dakota, USA Surface Geophysical data collected along Blacktail Creek in June 2017 near Williston, North Dakota, USA
The extraction of unconventional oil and gas (UOG) resources often produces highly saline waste waters, which can be released to the river corridor environment during spills and pipe leakage. In North Dakota, USA more than 8,000 spills were recorded from 2008-2015, and more than half of those spills were related to pipelines. Data collected for this study were related to UOG wastewater...

Wetland-scale mapping of preferential fresh groundwater discharge to the Colorado River Wetland-scale mapping of preferential fresh groundwater discharge to the Colorado River
Quantitative evaluation of groundwater/surface water exchange dynamics is universally challenging in large river systems, because existing methodology often does not yield spatially‐distributed data and is difficult to apply in deeper water. Here we apply a combined near‐surface geophysical and direct groundwater chemical toolkit to refine fresh groundwater discharge estimates to the...

MoisturEC: a new R program for moisture content estimation from electrical conductivity data MoisturEC: a new R program for moisture content estimation from electrical conductivity data
Noninvasive geophysical estimation of soil moisture has potential to improve understanding of flow in the unsaturated zone for problems involving agricultural management, aquifer recharge, and optimization of landfill design and operations. In principle, several geophysical techniques (e.g., electrical resistivity, electromagnetic induction, and nuclear magnetic resonance) offer insight...

Scenario Evaluator for Electrical Resistivity survey pre-modeling tool Scenario Evaluator for Electrical Resistivity survey pre-modeling tool
Geophysical tools have much to offer users in environmental, water resource, and geotechnical fields; however, techniques such as electrical resistivity imaging (ERI) are often oversold and/or overinterpreted due to a lack of understanding of the limitations of the techniques, such as the appropriate depth intervals or resolution of the methods. The relationship between ERI data and...
