SanctSound is a four-year project, managed by NOAA and the U.S. Navy, to better understand underwater sound within the National Marine Sanctuary System. Since the fall of 2018, and through the spring of 2022, these agencies will work with numerous scientific partners to study sound within seven national marine sanctuaries and one marine national monument, which includes waters off Hawai‘i and the east and west coasts.

NOAA is working to understand long-term changes in noise levels within the National Marine Sanctuary System as increasing noise from anthropogenic sources becomes a growing concern. The approach to managing ocean noise aims to reduce negative physical and behavioral impacts to species, as well as conserve the acoustic quality of their habitats.
Learn how marine organisms are impacted by anthropogenic ocean noise and what NOAA and partners are doing to help governments and industries address this issue.
