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.
