Researchers are uncovering just how large the impact of man-made noise is on ocean life. But there are some surprisingly simple ways we could tackle this overlooked pollution problem.
Sound is the most efficient means of communicating underwater, especially for many marine species. NOAA Fisheries works to better understand how marine animals use sound and the potential impacts of man-made noise on the underwater environment.
7 Ιουν 2024 · A growing body of research shows that the anthropogenic cacophony drowning out the natural noises of the ocean can have major consequences for marine species.
In the absence of man-made, biological, and transient sounds, ambient noise is wind dependent over the band from below 1 Hz to at least 50 kHz. Below 5-10 Hz, the dominant ambient noise source is the nonlinear interaction of oppositely propagating ocean surface waves.
4 Φεβ 2021 · Noise from shipping, construction, sonar and seismic surveys is "drowning out" the healthy ocean soundscape, scientists say. And an "overwhelming body of evidence" has revealed the harm...
1 Φεβ 2024 · There is extensive and emerging research highlighting the harmful effects of man-made noise on marine biota. These effects range from immediate death due to overexposure to extremely intense sounds to permanent or temporary injury.
1 Οκτ 2022 · Many animals, including whales, dolphins, and fish, produce unique sounds—and scientists are looking at how man-made noises are affecting their communication, behavior, and habitats.
