This is the 12th of a monthly webinar series hosted by members of the Underwater Acoustics SIG. This month’s webinar is presented by Anna Stork of Silixa and William Wilcock of Washington University. They will be speaking on the topic of Distributed Acoustic Sensing.
14:00 – 14:20 – Anna Stork – Distributed Acoustic Sensing: Technology and Applications
The talk will outline the technology behind Distributed Acoustic Sensing (DAS) and provide an insight into the applications of the technology, in particular it’s use in underwater environments. Recently it has been recognised that subsea cables deployed for communication purposes can also be used for monitoring natural and anthropogenic activity in the water and imaging and monitoring subsurface geology.
14:20 – 14:40 – William Wilcock – Distributed Acoustic Sensing on the Ocean Observatories Initiative Regional Cabled Array: Acoustical Observations
The Ocean Observatories Initiative Regional Cabled Array (OOI RCA) is a sophisticated cabled observatory in the Northeast Pacific Ocean that comprises two submarine cables that extend from Pacific City Oregon to support multidisciplinary networks of sensors on Axial Seamount and the central Oregon continental margin. In November 2021, a 4-day shutdown of the OOI RCA for maintenance provided an opportunity for a community test of distributed acoustic sensing on both cables. The data from the test is publicly available and is being used for a variety of seismic, acoustic and oceanographic signals. I will show examples of the acoustic signals recorded from fin whales, blue whales, ships and earthquakes.
14:40 – 15:00 – Q&A session
The webinar will take place on the 18th of May 2023 from 14:00 to 15:00
