*Seafloor Fiber Optic Sensing*

*Organized by the DAS RCN Marine Geophysics Working Group & IRISModerated
by Nate Lindsey and Meagan WengrovePresenters: Léa Bouffaut, Ethan
Williams, William Wilcock, Han Xiao, Pierre Martz, Mikael Mazur*

Recently developed photonic measurement techniques, including optical phase
interferometry, Distributed Acoustic Sensing (DAS) and State of
Polarization (SOP), are lowering the barrier to continuous observations of
elastic, acoustic and thermal wavefields at the seafloor. Fiber optic
datasets, collected using existing telecommunications and science cables,
provide first-of-kind recordings of earthquakes, ocean/solid-earth
interactions, hydrodynamic phenomena, and marine mammals. The Spring
Webinar will highlight some of the latest work in this space, and present
new open access datasets for the general science community to dive in to
this emerging field for themselves. Please see the attached flyer for more
information about the speakers.

This event will be held in Zoom Webinar format and will feature the
following presentations along with time for Q&A. A recording will be made
available on YouTube after the event.

- *Léa Bouffaut *(Cornell University) - DAS4Whales: A Case-Study of
Baleen Whale Monitoring using Distributed Acoustic Sensing
- *Ethan Williams *(CalTech) and *William Wilcock *(University of
Washington) - A Community Test of DAS and DTS on the Ocean Observatories
Initiative Regional Cabled Array
- *Han Xiao* (University of California, Santa Barbara) - The Moving
Sources of High-Frequency Microseisms
- *Pierre Martz *(Infinera Corp.) - Seismic Detection and Localization
using Submarine Cables
- *Mikael Mazur *(Nokia Bell Labs) - Environmental Sensing using
Coherent Optical Transceivers

Use of Distributed Acoustic Sensing is rapidly expanding in our community,
prompting the initiation of an Distributed Acoustic Sensing Research
Coordination Network to facilitate workshops, tutorials, and other
opportunities for sharing ideas and resources. This webinar is one in a
planned series on different topics within Distributed Acoustic Sensing.
