Distributed Acoustic Sensing (DAS) is a technology in which a fiber-optic cable is 1 turned into an acoustic sensor by measuring backscatter of light caused by changes in 2 strain from the surrounding acoustic field. In October 2022, 9 days of DAS and co-3 located hydrophone data were collected in Puget Sound near Seattle, WA. Passive data 4 was continuously recorded for the duration and a broadband source was fired from 5 several locations and depths on the first and last days. This dataset provides direct 6 comparisons between DAS and hydrophone measurements, and demonstrates the 7 ability of DAS to measure acoustics signals up to ~500Hz. 8 9
