Distributed Acoustic Sensing

Distributed Acoustic Sensing (DAS) is a potentially transformative technology in the geosciences and engineering. The rapidly increasing interest in DAS arises from its use in continuous arrays that can be kilometers in length while providing spatial resolution of meters and frequency response from millihertz to kilohertz. This mailing list provides a forum for discussion on all topics related to DAS technology including: applications, installation, data acquisition, handling and processing of data, engineering and scientific technical development, and advertisement of upcoming events, workshops, meetings, or other opportunities in the DAS community.

Hi DAS RCN Folks, The next meeting for the DAS RCN Hydrology Working Group will be May 11 at 1:00 pm PDT. We'll kick off the discussion with a brief talk by Verónica Rodríguez Tribaldos on "Aquifer monitoring using ambient seismic noise recorded on Dark Fiber DAS," followed by a discussion of hydrology-related issues in DAS. A Zoom link for the meeting is pasted below. The tentative agenda will be: 1. Introductions (Hausner) 2. Talk by Verónica Rodríguez Tribaldos: Aquifer monito… [more]
