Access remote and challenging terrains with SnowTEM

The SnowTEM Geoscanner

Advancing permafrost and talik mapping 

SnowTEM, a leap forward from the tTEM geoscanner platform, empowers precise mapping of permafrost and taliks. Researchers and environmental experts can delve into pristine frozen terrains, extracting insights crucial for climate studies, resource management, groundwater systems and ecological preservation.

The SnowTEM system comes with:

  • 331: 3×3, single turn. 3 m wide
    The default tTEM system
  • 333: 3×3, three turns. 3 m wide
    Deeper investigation than 331, but less focus on shallow layer resolution
  • 222: 2×2, two turns. 2 m wide
    Nearly Same depth of investigation as 331. Because of the smaller width it can access fields with narrow driving tracks

Exceptional versatility in frozen landscapes

SnowTEM surveys in linear paths or full 3D scans, delivers unparalleled subsurface imaging across applications. The system advances climate research by providing critical permafrost data and by this information climate change impacts on polar ecosystems can be accessed.
Accurate permafrost mapping is essential for designing stable and resilient infrastructure in regions prone to ground instability. SnowTEM assists in identifying suitable construction sites, optimizing foundation designs.

 

Achieving innovation through a proven and effective geoscanner platform

SnowTEM inherits tTEM’s legacy, embraced globally by companies and research institutions to deliver high-quality data in challenging field conditions with its advanced electronics, micdrocontrollers, and computers for maximum potential. The systems robust design ensures reliability and accuracy in measurements by enhancing our knowledge of permafrost and taliks, SnowTEM contributes to tackling the climate crisis and advocating for responsible land use practices.

Key features of the SnowTEM geoscanner:

  • Operational Mobility: Towed effortlessly by a snow scooter, ensuring access to remote and challenging terrains. 
  • Depth Penetration: Offers probing depths up to 130 m (430 feet) or 180 m (600 feet) depending on configuration, revealing intricate frozen layers. 
  • Power Supply: Equipped with a reliable 12V lithium battery for sustained operation. 
  • Pulse Frequency: Utilizes 2000 Hz for low-moment (3 Amp) and 630 Hz for high-moment (30 Amp) emissions. 
  • Precision Timing: Initiates measurements with the first gate centered within 4 microseconds from current turn-off. 
  • Connectivity: Wi-Fi and internet-enabled, allowing remote support and seamless data upload.

Dike Assessment – Netherlands

Read about the survey that was carried out in order to test the usability of the tTEM geoscanner in earth dike safety assessment. The presence, thickness and lateral extent of a thick clay layer was used to assess the safety in a spatial concern.

Borehole Siting – Togo

Get insights on the well-siting campaign that was carried out in Togo in 2022 using tTEM which resulted in recommendations of multiple borehole sites. The tTEM results located several fracture zones which resulted in very successful boreholes.

Aquifer Recharge – USA

Using tTEM to assess feasibility: Managed aquifer recharge, where excess water is used to recharge the groundwater aquifers, has been proposed as a means of curbing groundwater depletion in the Central Valley. However, locating new fields for recharge is difficult.

Characterizing Rivers – USA

Data were collected to achieve high-resolution information about subsurface geologic structure that can be used to delineate fresh-water/saline water contacts, delineate aquifer materials for water-resource investigations, and to inform hydrogeologic models.

Well Siting – Tanzania

Learn more about the well-siting campaign carried out with our tTEM system. The first target was a location with a potential for a thick unconfined aquifer to be present, while the second target was a confined aquifer system at greater depth, present in boreholes from nearby villages.
