Ice Thickness Measurement
The importance of geophysical surveys for ponds is growing in hard-to-reach places, rugged topography conditions and deep bogginess. The equipment is quite mobile and ensures surveys in hard conditions, makes it possible to obtain persistent information on the main elements of geologic structure and physical and mechanical environment properties.
Application of GPR methods makes it possible to project measures of pond bottom cleaning, disclose heterogeneous objects, project coastal zone. Within the framework of reconstruction programs of Moscow and Moscow region water bodies the specialists of GEOTECH have examined more than 30 water bodies.
Based on a wide range of GPRs produced by our company, for ice thickness measurements two versions of portable specialized GPR ” Ice Scanner ” were developed:
Hand-held Ice Scanner LD-1200.
The LD-1200 hand-held Ice Scanner is able to determine the structure and thickness of ice when in direct contact with its surface and at a separation from it of up to 15 cm. The maximum depth of freshwater ice sounding is up to 2 m.
Hardware and software complex LD-400.
Hardware and software complex LD-400 was developed on the basis of the “OKO-3” GPR complex with a “MG-400” antenna unit for quick determination of thickness and structure of ice, localization of heterogeneity, cracks, and other defects inside the ice massif in real time.
The device has a mass of 5.5 kg and can be installed on any vehicle by means of external suspension with a separation from surface of 0.5 – 1.0 m. The depth of sounding of freshwater ice – up to 8 m, sea ice – up to 2.5 m
