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.
