In permafrost landscapes, the ground remains mostly frozen throughout the year and liquid groundwater only occurs in certain locations or during anomalously warm periods. Understanding the spatial and temporal distribution of groundwater in these environments is extremely important as it can affect processes ranging from geotechnical soil stability to the release of greenhouse gases. In […]
The National Centre for Groundwater Research and Training in Adelaide, Australia has joined with Vista Clara Inc. to deliver a three-day, hands-on workshop focused on the application of Nuclear Magnetic Resonance (NMR) technologies for groundwater investigations. The course will be led by Dr David Walsh, President of Vista Clara Inc. and a leading developer of […]
Vista Clara Inc., a global leader in geophysical nuclear magnetic resonance (NMR) technology, is pleased to announce the launch of Vista Clara Geotech Ltd., a new Canadian company based in Surrey, British Columbia. Vista Clara Geotech Ltd. will manufacture magnetic resonance (NMR) instruments for geoscience applications and provide instrument sales, rentals, and customer service to […]
In recent years, Orsted and the Technical University (DTU) have performed laboratory research to use in-situ magnetic resonance measurements to further improve investigation of the key parameters that are known to drive seabed foundation engineering, including measuring soil strength, stiffness, density, and stratigraphy. In May 2025, Vista Clara president Dave Walsh introduced the new Harpoon® […]
Vista Clara, the leader in Magnetic Resonance (MR) technology for subsurface characterization, brings to the market Harpoon®, the world’s first integration of magnetic resonance measurements into a cone penetrometer (CPT) test tool. Harpoon® can be operated both offshore and on land to deliver real-time, continuous, high-resolution, in-situ data on both geotechnical and hydrogeological properties of […]
The main goal of this recent field study was to compare NMR-measured hydrogeologic results obtained using different high-resolution NMR tools. The NMR investigation was conducted at Ebey Island, WA. This site is in the Snohomish River estuary near Everett, WA, USA. The site is associated with a very shallow water table and a network of […]
Maximum temperature and pressure ratings for Javelin and Dart tools have been established through rigorous, instrumented physical testing, and our published temperature and pressure ratings are based on conservative interpretations of all available data. This rigorous and conservative approach ensures reliable and stable system operation and performance throughout the expected operating environments. In 2025, Vista […]
Vista Clara is pleased to introduce a new addition to our family of high-resolution Dart™ NMR logging tools: Helios Trek™. Helios Trek is a portable NMR soil core analyzer that can be used in both the laboratory and the field. This rugged and portable system is operated by the Dart™ NMR Control Unit and enables […]
Vista Clara is pleased to introduce a new family of high-resolution NMR logging tools in the Javelin® Slim and Dart™ lines of NMR probes. High-resolution NMR technology enables users to collect NMR data with vertical resolution as small as 1.5 inches (4 cm), providing extremely detailed characterization of the most critical hydrogeological properties: total and […]
Vista Clara’s Chief Scientist, Darya Morozov, provides an overview of the Dart product line, including descriptions of the basic components of a Dart system, the four different Dart probes that are currently available, and how Dart measurements can be performed in open or PVC-cased boreholes and with direct push and/or CPT deployment. Watch the video […]
Vista Clara’s Dave Walsh demonstrates how you can make a simple self-auguring PVC access tube from inexpensive materials. The video also demonstrates how to use this simple tool with a Dart NMR logging system to conduct quick, precise and high-resolution in-situ NMR measurements of water content in the shallow subsurface. Watch below: See more videos […]
We have updated our case study on the use of NMR geophysics to characterize managed aquifer recharge areas along the Cosumnes River in California. The original study presented direct push and surface NMR measurements from the spring of 2022, during typical spring runoff conditions. Following a historic storm runoff event in the winter of 2023, […]
Many critical mineral resources including lithium, uranium and potash are produced as brine groundwater resources. These critical minerals are typically found in highly saline groundwater in arid closed basins, and beneath dry lake beds. Production of brine-based mineral resources entailspumping mineral-rich brine from permeable brine aquifers and separating the minerals from water at the surface. […]
Vista Clara is pleased to announce a major revision to the Javelin® and Dart™ NMR logging tools. Introducing Numax™, a collection of NMR sensor electronics innovations that enable increased NMR signal amplitudes, reduced susceptibility to noise sources, and faster logging speed for the same resolution compared to previously available NMR logging tools. Vista Clara is […]
Watch the video by Vista Clara Chief Scientist, Darya Mozorov, PhD, on “In Situ NMR Measurements to Quantify Crude Oil at Bemidji Crude Oil Spill Site” that was presented at the Battelle Chlorinated Conference on Thursday, June 6, 2024 at 1:50 PM. The primary objective of this study was to use diffusion NMR with high-resolution […]
