ONMS is working to understand long term changes in noise levels (both anthropogenic and natural noise) within the National Marine Sanctuary System. Lastly, noise from acute sound sources can cause physical injury in the form of temporary or permanent hearing loss or tissue damage. Noise can also alter behavior and result in lower chances of survival and reproduction for marine organisms. Additionally, increased background noise can impact communication, such as the type of communication between mothers and offspring, or communication used in group dynamics. Scientific research suggests that anthropogenic noise can reduce opportunities for animals to hear sounds used for navigation, finding food, finding mates, and avoiding predators. Watch this video to see its deployment and to learn more about the importance of monitoring noise in our oceans! A mooring containing a hydrophone was deployed in Cordell Bank National Marine Sanctuary in October 2015. The increasing amount of noise from anthropogenic sources is a rising concern due to its potential to negatively impact marine ecosystems and organisms in several ways. Sources of underwater noise include merchant shipping traffic such as container ships and tankers, smaller recreational and commercial vessels, sonar and explosions used in military defense operations, pile drivers and dredging used in marine construction, airguns and other seismic sources used in energy exploration, active acoustic sources used in research activities, explosions used for platform removals, and introduction of noise from air and land sources such as roads and overflights. Increasing human activity within our oceans over the last 100 years has also meant increasing levels of noise. NOAA and the Office of National Marine Sanctuaries' 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. In general, sound can be perceived over greater distances than sight or smell underwater, and sound is the primary way that many marine species gather and understand information from other organisms and their environment in the ocean. Many marine organisms, including marine mammals, turtles, fish and invertebrates, rely on sound and hearing for their survival. Jenni Stanley has been deploying hydrophones at several national marine sanctuaries in order to characterize their soundscapes.
