A novel use of an existing fiber-optic cable off the coast of Spain has clued scientists in to how seismic noise is generated in the ocean.
To study a landslide along China’s Three Gorges Reservoir, researchers deployed underground fiber-optic sensors to monitor temperature, moisture, and strain.
Researchers jerry-rigged fiber-optic cables in a fjord to eavesdrop on blue whales, with possible applications ranging from seafloor mapping to meteorology.
Fiber-optic cables can provide a wealth of detailed data on subsurface vibrations from a wide range of sources. Machine learning offers a means to make sense of it all.
Telecom fiber repurposed as distributed acoustic sensing arrays can image near-surface structure and potentially improve seismic hazard mapping in urban areas.
A new book explores Distributed Acoustic Sensing, a technology with a range of applications across geophysics and related fields.
Distributed acoustic sensing offered researchers a means to measure ground deformation from atop ice-clad Grímsvötn volcano with unprecedented spatial and temporal resolutions.
Internet cables can be transformed into a string of dense seismic sensors, and this approach has now been shown to be highly useful for quickly monitoring seismicity after major earthquakes.
An ongoing project in northern Alaska is using pulses of laser light to monitor anthropogenic activity, ice quakes, and marine wildlife.
