D2.3 Report into DAS observations in relation to fibre technology used

Key Points

The report aims to explain key concepts in fibre optic sensing, particularly focusing on Distributed Acoustic Sensing (DAS).
Overview of DAS technology and its applications
Presentation of recordings from natural phenomena including whale calls, earthquakes, and ocean gravity waves
Discussion of coupling and signal effects during observations.
Highlighted diverse examples of recordings made with DAS technology
Discussed the implications of coupling effects on detection accuracy

Abstract

The purpose of this report is to introduce the reader to key concepts of fibre optic sensing often referred to as DAS (Distributed Acoustic Sensing). The DAS field laboratory in Svalbard is presented and several examples of various recordings ranging from whale calls to earthquakes and ocean gravity waves are presented and discussed with respect to coupling and signal effects.
