Overview

Numerical simulation and field testing demonstrate high-resolution seismic imaging of subsea permafrost in the Arctic continental shelf, highlighting a viable method to evaluate thawing ground.

Key Points

  • Subsea permafrost structures are successfully delineated through high-resolution seismic imaging, overcoming acoustic noise and abnormally high p-wave velocity layers.
  • Synthetic numerical experiments and linearized inverse problems optimize wavefield data misfits across multiple offshore survey configurations and structural models.
  • Application of least-squares reverse time migration to Canadian Beaufort Sea field data enables robust imaging, highlighting tools to monitor Arctic permafrost thaw.
