For some whales, sonar may provoke suicidal behaviour: study
Scientists have long known that some beaked whales beach themselves and die in agony after exposure to naval sonar, and now they know why: the giant sea mammals suffer decompression sickness, just like scuba divers.
Why do beaked whales return to a Navy sonar range despite frequent disturbance?
Using data from underwater robots, scientists have discovered that beaked whales prefer to feed within parts of a Navy sonar test range off Southern California that have dense patches of deep-sea squid. A new study published ...
Depression marks on seafloor suggest whales might be visiting prospective mining sites
A trio of researchers with the National Oceanography Centre in the U.K. has found depression marks on the sea floor in a very deep part of the ocean—they suggest the marks may have been made by deep-diving whales. In their ...
Diverse and abundant megafauna documented at new Atlantic US Marine National Monument
Airborne marine biologists were dazzled by the diversity and abundance of large, unusual and sometimes endangered marine wildlife on a recent trip to the Northeast Canyons and Seamounts National Marine Monument, about 150 ...
Scientists eavesdrop on little-known beaked whales to learn how deeply they dive
Scientists have reported the first dive depths for Gervais' and True's beaked whales, two of the least known beaked whale species known as mesoplodonts. The study is also the first to use a towed linear hydrophone array to ...
Study shows whales dive deeper and longer when exposed to human produced sonar
A combined team of researchers from Marine Ecology and Telemetry Research and the U.S. Navy's Naval Undersea Warfare Center Division has found evidence of whales diving deeper and longer than normal when exposed to sonar ...
The energetic cost of swimming at high speed when startled may be a factor in strandings of dolphins and whales
Dolphins swimming at top speed use more than twice the amount of energy per fin beat than dolphins swimming at a more relaxed pace, according to a study by scientists at UC Santa Cruz. The researchers also found that startled ...
First underwater video footage of the True's beaked whale
The True´s beaked whale is a deep-diving mammal so rarely seen that it often defies recognition at sea by researchers. As a result, we have little data about its distribution, abundance and calving rate - information essential ...
What causes whale mass strandings?
Around 600 pilot whales recently became stranded on a New Zealand beach, around 400 of which died before volunteers could refloat them back into the sea. Sadly, this kind of mass whale stranding has occurred since human records ...
