NOAA, the U.S. Navy, and partners have launched a new web portal that allows users to learn about and listen to underwater sounds throughout the National Marine Sanctuary System. As the sanctuary system celebrates its 50th anniversary, this resource provides another way to experience the wonders of America’s underwater treasures without getting wet.
The SanctSound portal invites the public to explore the results of a three-year project involving over 50 scientists from 20 institutions from all over the country who collected and analyzed underwater recordings from seven national marine sanctuaries and one marine national monument, including waters off Hawaii and the East and West coasts.
The web portal allows users to explore the sonic features of each sanctuary, and to make comparisons among locations to better understand how similar or different they are from each other. To do this, the portal describes sound information from each of its 30 recording locations in a comparable way. SanctSound generated 300 terabytes of data, all of which are accessible to download from the NOAA National Centers for Environmental Information (NCEI) Passive Acoustic Archive. Standard measurements extracted from these recordings are also archived at NCEI and made accessible through the web portal, which is hosted by the U.S. Integrated Ocean Observing System.
