The 2020 Distributed Acoustic Sensing (DAS) Virtual Workshop and Tutorial was held August 10, 12, and 17, 2020. Sessions included 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 provided an opportunity to get hands-on experience with real DAS datasets and synchronous presentations were complemented by asynchronous exercises. A Slack forum was provided to encourage energetic discussions througout the workshop and assist participants in networking. Recordings of the workshop and tutorial are now available on YouTube.
Please take a moment to review our Code of Conduct.
