Abstract
Summary
The main objectives of the surveys included high-resolution mapping of the seabed; determination of rock mass lithology; identification of tectonic disturbances and highly fractured or iced zones; measuring the depth of the top and bottom of permafrost soil bodies; and analysis of the composition, condition and properties of frozen soils in the rock mass.
The following methods were used to accomplish the above objectives:
- High resolution seismic survey (HRS)
- Continuous seismoacoustic profiling (CSAP) at low frequencies (LF) and high frequencies (HF)
- Side-scan sonar survey
- Multi-beam echosounder survey
- Transient electromagnetic resistivity survey (TEM)
- Drilling of exploratory wells
- Temperature logging.
The drilling and temperature logging data fully confirmed the geological model of the survey area. Thus, taken together, the methods made it possible to accomplish the goal.
