I’m David and I’m currently doing a post-doc at the University of Lisbon in Portugal focussing on a combination of seismology and oceanography with DAS submarine fibre optic cables in the Atlantic off the coast of Madeira Island. This was a completely new topic for me, having worked with land stations and OBS before, but it is such an interesting field and the stuff you can detect with these cables is mind blowing. With the EGU Seismology ECS group, we gave a brief and, I found, very helpful introduction into that topic, which is one of the reasons I like being a member of the representatives. Another reason is the great community there, being an easy point of contact with likeminded people on an international level.

Blue triangles: permanent broadband seismic stations. White triangles: permanent short-period seismic stations. Yellow star: local earthquake recorded during the data acquisition period.

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.
