Distributed Acoustic Sensing

Distributed Acoustic Sensing (DAS) is a potentially transformative technology in the geosciences and engineering. The rapidly increasing interest in DAS arises from its use in continuous arrays that can be kilometers in length while providing spatial resolution of meters and frequency response from millihertz to kilohertz. This mailing list provides a forum for discussion on all topics related to DAS technology including: applications, installation, data acquisition, handling and processing of data, engineering and scientific technical development, and advertisement of upcoming events, workshops, meetings, or other opportunities in the DAS community.

Global DAS monitoring month
2023-01-30 19:25:07 - 2023-03-23 13:38:31
The global DAS monitoring month is starting on Wednesday! This is exiting and thank you all for the positive feedback so far! More than 20 organizations have indicated their participation, and I know that a few more are still working in the background on contributing. You can find more information on the campaign and how to upload data on this webpage: https://www.norsar.no/in-focus/global-das-monitoring-month-february-2023 I will update this somewhat regularly during February You … [more]

DAS Dark Fiber Experiences Survey
2023-03-03 14:51:40
Good morning, I'm writing to share a survey to understand the research community's dark fiber leasing experiences. *The link to the survey is here: https://forms.gle/crqpXw7gVcj4tEtBA <https://forms.gle/crqpXw7gVcj4tEtBA>.* There are only five multiple choice questions, so it shouldn't take long to fill out. This survey will help us understand the barriers to further democratization of DAS, so your time spent responding will be appreciated by and useful for the broader community! *Note that… [more]

Global DAS month wrap up
2023-03-01 07:36:13
The Global DAS month of February 2023 is over. In total 159 earthquakes of M>5 were reported by USGS (see map below), amongst them the tragic series in Turkey. You can find a list here: https://earthquake.usgs.gov/fdsnws/event/1/query.geojson?starttime=2023-02-01%2000:00:00&endtime=2023-02-28%2023:59:59&minmagnitude=5&orderby=time Also, we have a 24h period of continuous recordings on February 14th. I would like to thank all participants for their efforts in contributing to this unique dataset… [more]
