Hello All,
The Distributed Acoustic Sensing (DAS) RCN is hosting monthly webinars on the application of DAS. This month's webinar will be given by Fabian Walter detailing its use for seismic studies in the cryosphere. The webinar will be on February 25th at 12:00 PM Eastern. Please see the information below, which includes details on how to register for the event.

Distributed Acoustic Sensing in the Cryosphere
Presented by: Dr. Fabian Walter, ETH Zurich

Abstract: Distributed acoustic sensing (DAS) dramatically increases seismic sensor coverage, turning kilometer-long fiber optic cables into thousands of seismic sensors. DAS and similar approaches image seismic sources in densely populated cities as well as deep ocean basins, far away from the nearest conventional seismic station. Like in many other disciplines, there is hope that DAS will fill critical monitoring gaps on glaciers, ice sheets and avalanche-prone terrain. This talk will present DAS measurements in the cryosphere, from technical aspects of cable deployment to signal quality and source studies. Given these first experiences, some conclusions of the potential and limitations of this technique may already be drawn.
This is a joint Distributed Acoustic Sensing Research Coordination Network (DAS RCN) and Incorporated Research Institutions for Seismology (IRIS) Webinar. You can find out more information and sign up for the DAS RCN mailing list at: https://www.iris.edu/hq/initiatives/das_rcn.
