Abstract:Distributed Acoustic Sensing (DAS) is a technology in which a fiber-optic cable is turned into an acoustic sensor by measuring backscatter of light caused by changes in strain from the surrounding acoustic field. In October 2022, 9 days of DAS and colocated hydrophone data were collected in Puget Sound near Seattle, WA. Passive data was continuously recorded for the duration and a broadband source was fired from several locations and depths on the first and last days. This dataset provides direct comparisons b… Show more
