7 Ιουν 2024 · Under normal circumstances, humans generate an exceptional level of noise at sea—from the din of propellers on massive shipping vessels to the grumble of oil drilling. These noises can drown out...
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.
1 Ιαν 2019 · Man-made noise has the potential to induce a stress response in marine fauna, defined here as “the physiological, hormonal, and behavioral changes that result from exposure to a stressor” (Wright et al., 2007).
21 Αυγ 2018 · Understanding the ambient sound conditions in marine mammal habitats is important because ambient sound limits the detection of and likely response to man-made sound (see Larsen and Radford, Chap. 5). The ocean is naturally noisy.
2 Ιουλ 2018 · Scientists now know that as man-made noise travels, it drowns out the natural ocean soundscape and makes it difficult for fish to hear each other.
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.
