GPR in permafrost
Yana river expedition, Yakutia


The penetration depth of a GPR signal in water or ice can reach tens of meters. This is due to the high dielectric constant of such media.

This feature makes it possible to effectively use GPR to search for minerals and paleontological material in permafrost conditions.

The expedition to the Yana River in the vicinity of the city of Batagai (Yakutia) was undertaken in April 2018 by our team with the involvement of additional specialists (divers).
The tasks included GPR scanning over the ice to search for accumulations of paleontological material at the bottom of the reservoir, including under the silt.
The presence of the identified objects was confirmed by underwater photography and also using divers.
The survey once again showed that ground-penetrating radar can effectively detect anomalies and artifacts under alluvial deposits.
Equipment used
  • GSSI SIR-3000 ground penetrating radar

  • 200 and 270 MHz antennas

  • Topographic wheel

  • A set of geodetic GPS\GLONASS receivers

  • "Buran" snowmobile

  • Conventional and underwater video cameras

  • A team of divers with equipment

  • Satellite communication equipment
GPR scanning was carried out from a snowmobile. A geodetic GPS receiver is attached to the antenna and provides a submeter accuracy of coordinates.

We also built a three-dimensional model of the stratigraphy of bottom sediments
