Anthropogenic Sound Exposure-Induced Stress in Captive Dolphins and Implications for Cetacean Health
Frontiers in Marine Science, 2021 Many cetaceans are exposed to increasing pressure caused by anthropogenic activities in their marine environment. Anthropogenic sound has been recognized as a possible stressor for cetaceans that may have impacts on health.

Repellence Effect of the New Sound for Underwater Speaker of Hydrofoil [PDF]
TransNav, 2015 In order to prevent hydrofoil colliding with cetaceans, the underwater speaker (UWS) has been installed to repel cetaceans. Yamada et al. (2012) analyzed and devised the UWS sound as it fits the cetaceans' acoustic properties to prevent the collision ...

Functional Roles and Ecological Importance of Small Cetaceans in Aquatic Ecosystems
Frontiers in Marine Science, 2022 Small cetaceans (dolphins, porpoises, and small toothed whales) occur from the poles to the tropics, and from freshwater habitats to the open ocean. Most ecological research has focused on the influence of abiotic factors on the abundance, distribution ...

Development of the Effective Underwater Speaker Sound Modulated by Audible Sound Frequency Range of Large Cetaceans for Avoidance with Ship Collision [PDF]
TransNav, 2015 The underwater speaker (UWS) has been installed on high speed vessels; hydrofoils (HF) with low-noise during their cruises, to avoid sudden collisions with large cetaceans, while its performance has remained uncertain because of the problem in quality of

Urgent assessment needed to evaluate potential impacts on cetaceans from deep seabed mining
Frontiers in Marine Science, 2023 Deep seabed mining operations, if permitted, could present significant risks to ocean ecosystems. Disturbance on any scale is likely to be long lasting and irreversible.

Sightings of Cetaceans in the waters of Yuzhny Sea Port (Hryhorivsky Estuary, Black Sea) in 2015–2016 [PDF]
Праці Теріологічної школи, 2016 The use of transformed coastal ecosystems by the Black Sea cetaceans is an important, but little studied issue. In 2015–2016, coastal visual observations of cetaceans were conducted in the waters of Yuzhny Sea Port.

First Unmanned Aerial Vehicle Observation of Epimeletic Behavior in Indo-Pacific Humpback Dolphins
Animals, 2022 Epimeletic behavior has been reported in various species of cetaceans and sometimes in wild populations during vessel-based surveys. Epimeletic behavior in cetaceans involves complex social interactions which have been described using observational and ...
