ScopeDistributed fiber optic sensing has generated tremendous excitement with applications including seismology, seismic imaging, hydrology, petroleum development, carbon dioxide sequestration, and geothermal energy. Distributed Temperature Sensing (DTS) became widely accessible about a decade ago. DTS can measure temperature along a fiber optic cable at sub-meter intervals, over distances of kilometers, and at sampling frequencies of 0.1 Hz or less. Distributed Acoustic Sensing (DAS) is a more nascent technology that is only now being tested for geophysical applications. DAS can acquire dynamic strain at sub-meter intervals, over distances of kilometers, and at sampling frequencies of 100 kHz or less. Both technologies can use standard telecommunication fiber optic cables for measurement. DAS, for example, has been used to sense earthquake movements in unused (dark) buried fiber optic communication networks. We invite presentations that discuss novel applications of distributed fiber optic sensing, interpretation of results of monitoring, and advancements in processing of data streams. This session will bring together practitioners from many disciplines to discuss opportunities, share experience, and suggest solutions to technical challenges.
