*Abstract: *Distributed Acoustic Sensing (DAS) is an emerging fiber-optic
sensing method that turns an optical fiber into a massive, meterscale,
multi-kilometer seismic array. In this webinar, I will begin by providing
an overview of the physics of fiber-optic sensing, and how we use
optoelectronic instruments connected to optical fibers, often embedded in
the telecommunications network, to make DAS measurements in the laboratory
and field. Then, I will discuss an on-going community calibration effort to
quantify DAS instrument response. Lastly, I will show results from recent
earthquake and ambient noise studies on the seafloor, in the cryosphere,
and beneath city streets -- with the aim to highlight how, why and where
DAS can make a difference when solving a particular earth science question.
