Please consider joining us at one or more of the following events to provide your input and get involved.It looks like Astound Broadband isn't available in your area yet. A DAS mailing list is available through the IRIS Message Center at: to provide a forum for discussion and for announcements of events, workshops, meetings, or other opportunities in the DAS community. The DAS RCN plans to gather community input through a variety of methods. ' Unused Fiber-Optic Cables Repurposed as Seismic Sensors', Eos, March 2019

The RCN will run for three years, after which it is expected that DAS will become permanently incorporated into new or existing facilities, and the community will become self-sustaining through community-wide facilities and professional societies. This research coordination network is supported by funding from the National Science Foundation under award EAR-1948737. Short courses will provide hands-on instruction in DAS-specific subjects such as data analysis, data management, and best field practices. Workshops will focus on producing white papers in areas of science applications, data management, and future technology developments. The proposed DAS RCN will use the mechanisms of workshops and short courses to engage a range of potentially interested groups.

Identify major challenges and next steps for supporting DAS science beyond the RCN.

Identify needed technical development (engineering and scientific).

Train a community of DAS users in the acquisition, handling and processing of DAS data.

Identify applications of DAS and develop a network of potential DAS users.

The DAS Research Coordination Network (RCN) has four main goals: DAS can complement and supplement conventional seismic sensors and arrays already used across a wide range of disciplines. The rapidly increasing 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.ĭAS applications in geosciences and engineering are numerous and growing including opportunities for deploying early warning systems for earthquakes, volcanic eruptions, continental and marine landslides, and avalanches, and for monitoring reservoirs and civil infrastructure. The fiber geometry can encompass a large volume that can be tens of cubic kilometers in size. DAS inherently possesses properties of a large-N seismic array. The fiber can be tens of kilometers in length and it can be located in shallowly buried trenches, in boreholes, or in some combination. The transformative potential arises from the fiber itself being the sensor and allowing for a spatially continuous measurement. DAS records ground motion along fiber-optic cables that are comparable to those obtained by single-component accelerometers or geophones. Distributed Acoustic Sensing (DAS) is a transformative technology in geosciences and engineering.
