Distributed Acoustic Sensing (DAS) is a form of fiber optic sensing that uses pre-existing telecommunication cables, such as the submarine cables along the ocean floor, and an interrogator unit. In the past, traditional marine instrument deployment had a limited deployment time and no real time monitoring, whereas DAS allows real time monitoring with little maintenance. This form of fiber optic sensing works by sending short pulses of light along a fiber, that are then sent back to the interrogator unit once they meet natural impurities within that fiber. These measurements can tell us strain at a given point on the fiber caused by disturbances from the environment. DAS has a wide range of applications in and outside of the marine environment. Traditionally, this form of fiber optic sensing has been utilized by seismologists for earthquake recognition, along with power cable, pipeline, and highway monitoring. It has only recently been explored in the coastal realm to study physical oceanographic processes. Marcela’s research aims to use DAS, in the lab and the field, to study ocean wave and hydrodynamics and applications of this sensor in coastal engineering and oceanography.
