What Distributed Acoustic Sensing (DAS) can find in the Atlantic Ocean

What Distributed Acoustic Sensing (DAS) can find in the Atlantic Ocean

The contribution from David Schlaphorst, the member of ECS SM division team. David is a PostDoc in Dom Luiz Institute (IDL), University of Lisbon, where he does seismology research. Introduction Distributed Acoustic Sensing (DAS) has been used exponentially over the last decade.If you are eager to learn the basics but in song form try this link. In this blog post, we want to dive into one example ...[Read More]

What is Distributed Acoustic Sensing?

What is Distributed Acoustic Sensing?

In this blog we give a succinct introduction to Distributed Acoustic Sensing for the starting seismologist, or the interested reader. The blog is by no means a complete overview and serves as a starting point for you to understand DAS and get started with the data. It was written by SM ECS members Ana Nap and Katinka Tuinstra.   By now, Distributed Acoustic Sensing (DAS) is a pretty widely kn ...[Read More]

From light to waveform: how fiber-optic cables can be repurposed as seismic arrays

What is Distributed Acoustic Sensing (DAS) and why is it exciting? Any observational seismologist would agree that our understanding of subsurface structure and dynamics is in great part limited by our ability to acquire data at the right locations, with the necessary spatial and temporal resolution. However, although our ultimate objective would be to cover the Earth with high-quality, broadband ...[Read More]
