2020 Distributed Acoustic Sensing Virtual Workshop and Tutorial
August 10th – 17th, 2020

The 2020 Distributed Acoustic Sensing (DAS) Virtual Workshop and Tutorial will be held August 10, 12, and 17, 2020. Sessions will include varied talk formats and topics related to collecting and using DAS data aimed at a broad audience, from new users to experienced researchers. The tutorial will provide an opportunity to get hands-on experience with real DAS datasets and synchronous presentations will be complemented by asynchronous exercises. A forum will be provided to encourage energetic discussions througout the workshop and assist participants in networking.

Please take a moment to review our Code of Conduct.

Key Dates:

  • Registration Opens - July 1, 2020
  • Registration Closes - August 1, 2020
  • Workshop and Tutorial - August 10, 12, 17, 2020

Organizers:
