The finback whale is protected as an Endangered species by the Federal Endangered Species Act and as a Federally-designated Endangered species by Florida’s Endangered and Threatened Species Rule. Fish and Wildlife Service Species ProfilePrintable version of this page. In this example of a blue whale call, the spectrogram (upper image) plots time (horizontal axis) versus frequency (vertical axis), with warm colors representing high acoustic intensity. The 52Hz whale may feel lonely, as Zeman suggests, but it's equally possible that it doesn't. The most frequent origin locations were near Nova Scotia, Canada, Northeast Brazil, and Northwest Africa. Click here for more information on earthquakes. They were whale songs, and they were similar to blue whale calls, but there was one big difference. Here's The Finback Whale Sound Effects for the Youtube Audio Effects Library and i hope you like it To discover the true nature of the 52Hz whale, we can only wait – and listen. Maybe the whales are changing their songs for another reason entirely. The call of a northeast Pacific blue whale (380k, requires QuickTime ) is perhaps the best known to date. Blue Whales The 52Hz whale may be a member of this group that sometimes wanders off on its own. In this paper an attempt is made to correlate our ob Sign up for the Ocean Explorer E-mail Update List.

Stats: Weight: 55,000 - 90,000 lbs (25 - 41 tons) Length: 37 - 56 ft (11 - 17 m) Diet: Plankton and small fish Status: Endangered However, it would have to be installed where the mysterious whale has been detected in the past, such as off the west coast of the United States. It's one of the animal kingdom's great mysteries. An array of hydrophones called SOSUS, built by the US Navy to detect enemy submarines, picked up some strange signals. Measuring in at up to 90 feet long they are considered the second biggest whale in existence in terms of length right after the blue whale.. They can weigh up to 80 tons (2000 pounds). Spectrogram of an unidentified sound, referred to as "Slow Down." These pulses typically are produced in … Nobody has managed to record a hybrid whale's calls. (1.1Mb, Requires QuickTime .). Andra M. Bobbitt, GIS/Research Assistant The military routinely uses the characteristics of these blade lines to identify ship characteristics, class, and often individual vessels. ), Finback whale prepares for the 50 minutes dive, Antarctica, Razorback whale, common rorqual, Herring whale, Baleine fin, Fin-backed whale, Arctic Ocean, Atlantic Ocean, Indian Ocean, Pacific Ocean, Southern Ocean, Arthropods, Crustaceans, Zooplankton, Phytoplankton, Fish (Herring, Capelin, Cod), Sub Species – Northern & Southern Finbacks, "Finback whales communicate with each other using a low frequency sound ranging between 16-40 Hz", "Finback whales have a rare asymmetrical pigmentation which helps them catching schools of fish", Disclaimer, Terms of Use & Privacy Policy. "What you're seeing on the website is near real-time data," says Baumgartner. Each sound lasts from one to two seconds, and various combinations of sound occur in patterned sequences of 7 to 15 minutes. It will be like looking for a needle in the world's largest haystack. The film's Kickstarter page strongly emphasises the idea that "52" is a lonesome beast. But many, from filmmakers to whale researchers, are now on the lookout.

Typically, these signals are short (< 1s) pulses that downsweep from about 23 Hz to 18 Hz. It's been nicknamed "the loneliest whale in the world". The gestation period lasts up to 11.5 months, with the female giving birth to one calf. To sign up for alerts, please log in first. Fin whales produce low frequency vocalizations that are called “20-Hz pulses” even though they are usually downward sweeps in frequency from about 30 to 15 Hz. The distinctive dorsal fin of the fin whale gives the species its name. The sound rises rapidly in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km. But his team has recently been on the case. Finback whales are monogamous breeders (breeds with one mate).
extremely loud volcanic tremor-like signals, the call of the northeast Pacific blue-whale, National Oceanic and Atmospheric Administration. The whale's call has been gradually deepening and is expected to be closer to 47Hz today, though it’s been a few years since any recordings were identified.
"It's by far the best way to pick up when an animal in a group is making a call." Click here for more information on volcanic tremors.
Fin Whales tie their cousins the Blue Whales for making the lowest-frequency sounds of any animals.
My goal is to ask scientists to really consider this.". http://oceanexplorer.noaa.gov/explorations/sound01/background/seasounds/seasounds.html. ", "It's been a real struggle," admits Zeman, who has disagreed with some over the nature of the 52Hz whale's experience. Residents in Greenland are allowed to hunt based on the “aboriginal subsistence whaling” clause, which states that aboriginal groups can still hunt because of their cultural hunting tradition (National Oceanic & Atmospheric Administration, n.d.). But not always. The signals are then transmitted via satellite to computers at WHOI, which quickly process the data and publish it on the web. Normally sounds from these whales are too low for …
The sound of this earthquake (44k, requires QuickTime ), located near Astoria Canyon, was recorded by a U.S. Navy SOund SUrveillance System (SOSUS) hydrophone. The main threat to the finback whale today is collisions with ships and fishing nets. Complicating the picture further, the whale hasn't been calling at 52Hz for many years, according to John Hildebrand of the Scripps Institution of Oceanography in California. His findings would be discussed for years to come.

The tremor signals typically appear as discrete packets that last for 4-5 minutes, with brief periods of quiescence for roughly 30 seconds, followed by the beginning of the next signal packet. "The latest stuff is less than two hours old.
