10 Απρ 2019 · Ship engines, underwater blasts, sonar and oil drilling are filling the seas with sound. Researchers are now trying to pin down the damage humanity’s growing acoustic footprint has on ocean life.
18 Σεπ 2020 · A great variety of natural and artificial sound sources are detectable in the ocean, including earthquakes, shipping noise, breakup of floating ice sheets, oil exploration, rainfall, breaking waves, and large marine mammals, such as blue whales capable of signaling each other over ocean basin distances.
Consider relevant updates to existing regulation e.g. to consider impacts as well as noise levels, and to consider soundscapes rather than individual noise sources; Explore research and policy gaps in understanding underwater noise baselines e.g. for MSFD;
23 Μαρ 2019 · This paper, having a tutorial flair, concerns the use of ray modelling and in particular eigenray analysis to obtain increased knowledge and understanding of underwater acoustic propagation. Acoustics is important for all underwater systems for object detection, classification, surveillance systems, and communication.
Understanding Ocean Acoustics emphasises such applications and issues relevant to studies of the ocean environment and aquatic life. Its focus is therefore environmental research and development using low frequencies relevant to fish and sea mammals.
25 Σεπ 2024 · A mysterious sound heard booming from deep under the ocean waves has finally been traced to a fascinating source. First recorded in 2014 in the west Pacific, t he "biotwang" is actually the...
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...
