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.

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.

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.

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.
