The California Department of Water Resources has selected a team of consultants led by Ramboll to conduct airborne electromagnetic surveys in California’s high- and medium-priority groundwater basins. The surveys will provide a standardized statewide dataset which will improve understanding of large-scale aquifer structures and support implementation of the Sustainable Groundwater ...
June 27, 2019. Long Beach Marriott, Long Beach, California. ImpulseRadar would like to extend our thanks to the panel members and all those who attended to make this a successful event. We look forward to participating in similar events in the future to share knowledge on the role of GPR in SUM and SUE workflows. ...
The speakers will present and discuss a range of topics including: An introduction to Subsurface Utility Mapping (SUM) as a professional service and the guidelines/standards established by ASCE 38-02 Understand the financial, operational, and PR risks and benefits of performing adequate SUM Discuss best practices for pre-planning, execution, and ...
CrossPoint® offers a practical approach to managing single or multi-line data sets, including online map support, for efficient subsurface mapping. Designed primarily to support the CrossOver® series of dual-channel antennas, CrossPoint® also supports Raptor® data files, as well as some third-party GPR file formats. The ...

GPR is a proven non-destructive method for the evaluation of roads and other paved surfaces, because of its ability to detect subsurface defects and measure construction layer thickness. The key advantage of Raptor® is its ability to collect high quality 3D data much faster than any other commercial GPR system. ...
Although the park’s iconic hydrothermal systems are well mapped at the surface, their subsurface groundwater flow systems are almost completely unknown. The HEM survey, operated by SkyTEM, will provide the first subsurface view of Yellowstone’s hydrothermal systems, tracking the geophysical signatures of geysers, hot springs, mud ...
Measurement of subsurface conditions by the seismic refraction method requires a seismic energy source, trigger cable (or radio link), geophones, geophone cable, and a seismograph (see Fig. 1). ...
Also included on Halliburton’s new microsite is a description of the company’s advancements in the field of 3-D, subsurface fracture mapping, along with information on how the company’s Advanced Dry Polymer Blender technology is being used to reduce chemical additive usage even further. ...
The company’s newest product, gINT Enterprise, maximizes the value of centrally managed subsurface data through multi-project reporting and dramatically extended querying power. Offering a powerful and efficient solution for transportation operations, engineering consultancies, plants, campuses, and state and federal agencies with vast quantities of geotechnical data, gINT ...
Willowstick Technologies, the leading provider of innovative subsurface water mapping services, was recognized Wednesday as one of the top earth-friendly businesses in the state, winning an award in the category of Green Business at Utah Business magazine’s iQ Awards.In a ceremony at Salt Lake City’s Wells Fargo Bank Building, Willowstick was recognized for ...
Conductive ground consisting of graphite rocks, identified by the Aeroquest survey, will be used for the placement of the earth electrodes. This ability to map the subsurface with improved accuracy provides land care managers with data necessary to economical select drill targets and identify areas requiring follow-up ground surveys. ...
