From rain to rills, DAS detects prerequisite to southwest U.S. flash floods
Data showed when the patter of rain transforms changed to a rush of water coursing down a rill.
To better understand whales, geophysicists explore old data in new ways
New research expands the limits of traditional bioacoustic monitoring by finding whale signals in unexpected places.
Ear to the seafloor: using DAS to help harness offshore wind energy
California is looking to build offshore wind electricity generation―distributed acoustic sensing on existing cables could help site these projects.
Cloud case study: Using DAS to listen to glacial meltwater streams
A recent paper used DAS on Rhône Glacier in the Swiss Alps to infer the discharge of meltwater streams. We talked with one of the authors about how they wrangled this large dataset.
NSF SAGE/GAGE Community Science Workshop highlights the breadth of the geophysical toolkit
The techniques in our geophysical toolkit have grown exponentially over the years. By understanding research in these fields using these tools, we can see the applications to geophysics and bettering society.
Fiber-Optic Cable Technology: A New Way to Study Firn in Greenland
Researchers interested in determining the depth of the firn layer within a glacier might spend six hours drilling, extracting, and analyzing a core in frigid temperatures. Recent research poses a new method for determining firn layer depth based on an exciting technology finding expanding applications in seismology.
Many Hands Make Light Work at Distributed Acoustic Sensing Field Experience
The hands-on Distributed Acoustic Sensing (DAS) Field Experience was held at the Colorado School of Mines in Golden, Colorado, gathering participants for intensive work exploring this exciting technology and the observations it enables.
