Underwater noise from submarine turbidity currents [PDF]
The Journal of the Acoustical Society of America, 2021 Submarine landslides and associated turbidity currents can be orders of magnitude larger than their terrestrial equivalents. Their prevalence globally is hugely underrepresented by in situ observations. In addition to their importance in mass transport and morphologic change they can pose significant threat to coastal communities and subsea ...

, 2021 Underwater ambient noise is primarily a background noise which is a function of time, location, and depth. Background baseline of the noise in ocean is represented by ambient noise generated from the ocean surface due to wind and rain. This understanding pertained to ambient noise under various conditions will help in improving the signal-to-noise ...

Directional underwater noise estimation [PDF]
The Journal of the Acoustical Society of America, 1986 In the waters surrounding Australia and New Zealand, there are features of the measured three-dimensional ambient noise field (20–200 Hz) which appear similar to those found in the northern hemisphere where shipping noise is dominant. In the latter case, this shipping noise can be enhanced when vessels are at high latitudes or over sloping bathymetry ...

Range-only underwater target localization : error characterization [PDF]
, 2016 Locating a target from range measurements using only one mobile transducer has been increased over the last years. This method allows us to reduce the high costs of deployment and maintenance of traditional fixed systems on the seafloor such as Long

ORCA-SPOT: An Automatic Killer Whale Sound Detection Toolkit Using Deep Learning [PDF]
, 2019 Large bioacoustic archives of wild animals are an important source to identify reappearing communication patterns, which can then be related to recurring behavioral patterns to advance the current understanding of intra-specific communication of non ...

Systematic cavitation tunnel tests of a propeller in uniform and inclined flow conditions as part of a round robin test campaign [PDF]
, 2016 The effect of shaft inclination can induce important unsteady hydrodynamic phenomenon usually associated with small and high-speed craft. This paper presents systematic cavitation tunnel tests with a 214 mm diameter model propeller of a catamaran ...

Environmental Impact of Underwater Noise
Journal of Maritime & Transportation Science, 2022 The description of sound as a form of energetic pollutant is very complex as is also its impact on aquatic life. Human activities causing continuous and implosive underwater noise, such as marine traffic, maintenance of ships, coastal tourism, marine research, military, offshore energy platforms, generation of ocean energies and construction operations
