GEOELECTRICAL CHARACTERISTICS OF SAMOYLOV ISLAND COASTLINE (LENA RIVER DELTA)
https://doi.org/10.18303/2619-1563-2018-4-5
Abstract
Permafrost structure of Samoylov island coastline was determined with geological and geophysical methods. Geoelectrical model based on electrical resistivity tomography and ground penetrating radar data was compared with geological observations. Structure of contact between different types of frozen deposits was determined, influence of river water on permafrost (talik borders were determined) was estimated, ice wedges of different thickness were localized. Results of the study could be useful in permafrost research in the region because studied objects are typical in Lena delta.
