Application of Distributed Acoustic Sensing in Geoscience and Beyond Martin Landro

“At the Center for Geophysical Forecasting (CGF) at NTNU we have focused on acquisition and analysis of DAS (distributed acoustic sensing) data for several years. I will discuss and show various examples of DAS-data and how such data can be utilized for geophysical analysis. On a fiber optic cable between Ny Ålesund and Longyearbyen at Svalbard in the Arctic, we have recorded a large number of whale calls and earthquakes. Examples of how distant storms in the South Atlantic can be observed in an Arctic fjord will be shown. Currently we are investigating if DAS can be used to monitor changes in quickclay during a road construction period in Norway.”
