[SZ4D] TOMORROW - JOINT IRIS & DAS RCN WEBINAR: Seafloor Fiber Optic Sensing, 3/30 at 12-3PM Eastern

[SZ4D Office]

*Seafloor Fiber Optic Sensing*Wednesday March 30th at 12:00-3:00 PM Eastern

Organized by the DAS RCN Marine Geophysics Working Group & IRISModerated by
Nate Lindsey and Meagan Wengrove

*Presenters*: Léa Bouffaut, Ethan Williams, William Wilcock, Han Xiao,
Pierre Martz, Mikael Mazur

*Register*: https://zoom.us/webinar/register/WN_brOwlv2XRjO2jpVkgKw0Tw

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 into 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.

If you are new to DAS or interested in being part of the DAS RCN
community, you can find out more information and sign up for the DAS RCN
