Thank you again to our presenters, Carlos Becerril and Julián Pelaez both
at CNRS-Géoazur.
Abstract: In this talk we share some results on the potential of seafloor
DAS towards the detection of tsunami waves by estimating the expected
strain signal on a submarine cable due to the hydrostatic pressure and the
compliance effect from the changing sea-surface level. We will also discuss
observations of temperature-dominated signals embedded in conventional DAS
recordings, which in turn provide us with an unconventional sight into the
dynamics of the underwater environment. Observation of such phenomena in
deep ocean environments may lead to adoption of DAS sensors into the suite
of instrumentation considered for development of future ocean observatories
and tsunami warning systems.
