Correction: A Risk Function for Behavioral Disruption of Blainville’s Beaked Whales (Mesoplodon densirostris) from Mid-Frequency Active Sonar
There is increasing concern about the potential effects of noise pollution on marine life in the world's oceans. For marine mammals, anthropogenic sounds may cause behavioral disruption, and this can be quantified using a risk function that relates sound exposure to a measured behavioral response. Beaked whales are a taxon of deep diving whales that may be particularly susceptible to naval sona...
متن کاملBiosonar performance of foraging beaked whales (Mesoplodon densirostris).
Toothed whales (Cetacea, odontoceti) emit sound pulses to probe their surroundings by active echolocation. Non-invasive, acoustic Dtags were placed on deep-diving Blainville's beaked whales (Mesoplodon densirostris) to record their ultrasonic clicks and the returning echoes from prey items, providing a unique view on how a whale operates its biosonar during foraging in the wild. The process of ...
متن کاملForaging Blainville's beaked whales (Mesoplodon densirostris) produce distinct click types matched to different phases of echolocation.
Blainville's beaked whales (Mesoplodon densirostris Blainville) echolocate for prey during deep foraging dives. Here we use acoustic tags to demonstrate that these whales, in contrast to other toothed whales studied, produce two distinct types of click sounds during different phases in biosonar-based foraging. Search clicks are emitted during foraging dives with inter-click intervals typically ...
متن کاملSounds recorded in the presence of Blainville's beaked whales, Mesoplodon densirostris, near Hawai'i.
During a combined visual and acoustic cetacean survey of the Hawaiian Islands in 2002, four midfrequency sounds were recorded in close proximity to a group of Blainville's beaked whales, Mesoplodon densirostris. These sounds included one frequency-modulated whistle, and three frequency- and amplitude-modulated pulsed sounds, with energy between 6 and 16 kHz. Until recently, little was known of ...
متن کاملMESOPLODON BEAKED WHALES (Mesoplodon spp.): Western North Atlantic Stock
STOCK DEFINITION AND GEOGRAPHIC RANGE Within the genus Mesoplodon, there are four species of beaked whales that reside in the northwest Atlantic. These include True's beaked whale, Mesoplodon mirus; Gervais' beaked whale, M. europaeus; Blainville's beaked whale, M. densirostris; and Sowerby's beaked whale, M. bidens (Mead 1989). These species are difficult to identify to the species level at se...
