Whales dive to nearly 2 miles depth, for over 2 hours Scientists monitored Cuvier's beaked whales' record-breaking dives to depths of nearly two miles below the ocean surface and some dives lasted for over two hours, according to results published March 26, 2014, in the open access journal PLOS ONE by Gregory Schorr from Cascadia Research Collective and colleagues. Distributed throughout the world's oceans, the Cuvier's beaked whales' frequent dives deep into the ocean make them...

Stranded Whales Lead Scientists To Discovery Of A New Species
2014-02-05 14:06:36

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered a new whale species that lives in the deep ocean waters beyond the edge of the continental shelf. Researchers, publishing a paper in the journal Marine Mammal Science, say they discovered Mesoplodon hotaula after studying seven animals stranded on remote tropical islands in the Indian and Pacific Oceans. The first specimen was a female found on a beach in Sri Lanka more than 50 years ago. M. hotaula are...

Lawsuit Lands US Navy's Potentially Harmful Sonar Training Exercises
2014-01-28 10:58:03

Brett Smith for redOrbit.com - Your Universe Online In December, the National Marine Fisheries Service authorized Navy sonar training exercises off the coasts of Hawaii and California through 2018. This authorization came despite admittance by the Navy that the work will kill up to 155 marine mammals, cause more than 2,000 lasting injuries and generate approximately 9.6 million instances of temporary hearing loss – as well as disruptions of natural activities. On Monday, groups led by...

Military Sonar Disrupts Behavior Of Blue Whales
2013-07-03 14:31:38

Michael Harper for redOrbit.com - Your Universe Online A new study has found whales do not care for the sound of the sonar used by militaries to detect submarines. Researchers from Duke University in Durham, North Carolina, have observed the behavior of whales as they come into areas where sonar is being used and found these marine mammals may even avoid venturing into new feeding areas when they hear sonar. The results of this research suggest militaries should refrain from...

Rare Whale Found On New Zealand Beach

Michael Harper for redOrbit.com — Your Universe Online Perhaps one of the greatest things about science is that there´s still so much left to discover. Though scientists have been studying and cataloguing the world for hundreds of years, there are still creatures and mysteries which continue to elude us. Take, for instance, the spade-toothed whale. According to the Telegraph, scientists weren´t aware of this species of whale until some pieces of bone were discovered on...

Scientists know that the blood and tissues of some deceased beaked whales stranded near naval sonar exercises are riddled with bubbles. It is also well know that human divers can suffer from bubbles-induced decompression sickness, also known as the bends. What researchers know comparatively little about is how living marine mammals handle the compression of lung gas as they dive deep and then resurface. Now, in a study published online in the Proceedings of the Royal Society B, a team that...

In a recent study to be published on April 27, 2011, in the peer-reviewed open-access journal PLoS ONE, Dr. Elliott Hazen and colleagues found that oceanographic and prey measurements can be used to identify beaked whale foraging habitat. The research team from Duke University, Woods Hole, and the Naval Undersea Warfare Center listened for foraging beaked whales and measured ocean features and distributions of prey off the east coast of Andross Island in the Bahamas. Their manuscript provides...

Scientists have long been aware of a link between naval sonar exercises and unusual mass strandings of beaked whales. Evidence of such a link triggered a series of lawsuits in which environmental groups sued the U.S. Navy to limit sonar exercises to reduce risk to whales. In 2008, this conflict rose to the level of the US Supreme Court which had to balance potential threat to whales from sonar against the military risk posed by naval forces inadequately trained to use sonar to detect enemy...

A combination of the biology of marine mammals, mechanical vibrations and acoustics has led to a breakthrough discovery allowing scientists to better understand the potential harmful effects of sound on marine mammals such as whales and dolphins. An international team of researchers from San Diego State University, UC San Diego, and the Kolmården Zoo in Sweden has developed an approach that integrates advanced computing, X-ray CT scanners, and modern computational methods...

Rocket science is opening new doors to understanding how sounds associated with Navy sonar might affect the hearing of a marine mammal "“ or if they hear it at all. The same type of large industrial sized X-ray scanners that NASA uses to detect flaws in the space shuttle's behemoth solid fuel rockets is now allowing scientists to peek inside the giant head of a whale. The scans are providing detailed three-dimensional replicas of a whale's hearing anatomy using a breakthrough method...

Blainville's Beaked Whale, Mesoplodon densirostris
2013-08-17 13:31:16

Blainville’s beaked whale (Mesoplodon densirostris), also known as the dense-beaked whale, can be found in a large range that includes the warm and tropical waters of all oceans. It prefers to reside at depths between 1,600 and 3,000 feet and does not migrate. This species received its common name from Blainville, the man who classified it as Delphinus densirostris after studying a description of a piece of one individual’s nose located in the Paris Museum. In 1846, John Edward Gray...

Sowerby's Beaked Whale (Mesoplodon bidens), also known as the North Atlantic/North Sea Beaked Whale, was the first beaked whale to be described. Its name, bidens, derives from the two teeth present in the jaw, now known to be a very common feature among the family. It is altogether a rather typical representative of the genus. Physical description Sowerby's Beaked Whale has a typical body shape for the genus, and is mainly distinguished by the male's dual teeth that are found very far...
