Monitoring baseline ocean noise is critically important to understand both natural and anthropogenic changes in the marine ambient sound environment. As of this week, a network of 11 ocean noise reference stations has been established in U.S. waters to measure changes and trends in natural and man-made ocean noise.  Natural sounds ranging from whale calls and volcanoes to anthropogenic sounds from shipping and oil/gas exploration are recorded by the moored, underwater hydrophones developed by PMEL engineers and scientists and deployed in collaboration with NMFS-OST, all the Fisheries Science Centers, NOS Marine Sanctuaries, and the National Park Service. The establishment of a long-term record provides fundamental data needed to understand how increased noise in the ocean may affect marine life and ocean health.
