2021 Distributed Acoustic Sensing: Scientific Frontiers and Community Needs
Virtual, Eastern Daylight Time Friday, August 13th, 2021, 11am–3pm

Distributed Acoustic Sensing (DAS) has attributes that make it a transformative technology in geosciences and engineering. The increased interest in DAS arises from its potential to be used in continuous arrays that are kilometers in length while providing spatial resolution of meters and frequency response from millihertz to kilohertz. This 4-hour workshop will start with an overview of DAS, focus on the science results emerging from DAS utilization through talks and popup presentations, and use limited breakout sessions to explore the community’s needs and vision for the utilization of this new technology.

We are planning to highlight a range of DAS topics including:

  • Low-frequency DAS and geomechanics observations
  • Environmental seismology
  • Infrastructure, engineering, near surface applications
  • Cryosphere & hydrology applications
  • Time-lapse imaging and monitoring
  • Deployment techniques and data management in the field

Participants will:

  • Be able to identify applications of DAS and needed technical developments (both engineering and scientific)
  • Be able to describe major challenges and next steps for supporting DAS science and applications in the long term
  • Become part of a developing network of potential DAS users, get connected to the DAS Research Coordination Network, and learn about future opportunities for hands-on DAS experience
  • Engage in conversations about the role of DAS between the geodesy, seismology, and engineering communities

Please take a moment to review our Code of Conduct.

Key Dates:

  • Talk Submission Deadline - June 25, 2021
  • Registration - August 1, 2021 - Through GAGE/SAGE Workshop
  • Workshop - August 13, 2021

Organizers:

  • Leads - Eileen Martin (Virginia Tech), Rachel Hatch (University of Nevada, Reno), Ariel Lellouch (Stanford), Dante Fratta (University of Wisconsin-Madison), Kasey Aderhold (IRIS)
  • Supporting - Scott Tyler (University of Nevada, Reno), Herbert Wang (University of Wisconsin-Madison), Robert Woodward (IRIS), and the DAS RCN

If you have questions and would like to get in touch with the organizers, please email das-workshop@iris.edu. For more information about the full workshop, please go to the 2021 GAGE/SAGE Workshop website

For more information on the DAS Research Coordination Network, please go to the DAS RCN website. If you are interested in future DAS events or opportunities, please subscribe to the DAS RCN mailing list.

We are seeking submissions for pre-recorded lightning talks and a few selected full-length talks. We especially encourage those talks that highlight:

  • Low-frequency DAS and geomechanics observations
  • Environmental seismology
  • Infrastructure, engineering, near surface applications
  • Cryosphere & hydrology applications
  • Time-lapse imaging and monitoring
  • Deployment techniques and data management in the field

If you are interested in presenting a lightning talk or potentially being selected to give a full-length talk, please fill out this Google Form with your title, brief description and contact information by Friday, June 25. Only lightning talks submitted by June 25 will be considered for part of the live program, but others submitted later may be included in the YouTube playlist of lightning talks.
