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.
1 Μαρ 2022 · It has been investigated in distinct shallow water environments with high anthropization. However, the main sources of noise are man-made signals (Parbery-Clark et al., 2009), which can be either continuous or intermittent; occupying mainly low-frequency bands (Kuta and Richardson, 1996).
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.
10 Φεβ 2024 · Loud man-made noises have also been linked to mass breaching events around the world. But the loudest underwater noise comes from naval sonar devices. This works similarly to echolocation, a type of sound used by whales and dolphins, and can travel hundreds of miles underwater.
This handbook shows the latest research data and regulatory issues of man-made noise on marine mammals, turtles, amphibians, fishes, and invertebrates.
In 2010, NOAA committed to improve tools that the agency uses to assess the effects of man-made sound on whales, dolphins, and porpoises. 12 Current number of underwater reference stations in U.S. waters tracking ocean noise levels over time for the federal government.
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.
