Satellite-linked tags have been used to track and study whale movement, with associated data suggesting that Cuvier's beaked whale follows a stereotypical dive pattern, often to a depth exceeding 800 m (2,624 ft 8 in). These dives, likely to be hunting expeditions, may last from 15 to 30 minutes, though sometimes considerably longer, before re ...
The greatest dive depth reported from tagged blue whales was 315 meters (1,033 ft). [69] Their theoretical aerobic dive limit was estimated at 31.2 minutes, [70] however, the longest dive measured was 15.2 minutes. [69] The deepest confirmed dive from a pygmy blue whale was 506 meters (1,660 ft). [71]
Animals have been observed spending more than an hour at or near the surface breathing. Beaked whales are often seen surfacing synchronously, but asynchronous surfacing has also been observed. [36] In March 2014, a study by Cascadia Research revealed that Cuvier's beaked whales were recorded to dive at least 2992 m in depth, a mammalian record ...
In beaked whales, the descent rate was consistently faster than ascent rate, at about 1.5 metres per second, regardless of dive depth, and at a steep angle of from 60 to 85 degrees, Fluke rate for Z cavirostris was higher at the start of the dive, but reduced by about 50 m depth, with a constant descent rate, consistent with buoyancy reduction ...
Individual captive animals have been recorded at depths between 400 and 647 m below sea level, [74] while animals in the wild have been recorded as diving to a depth of more than 700 m, with the greatest recorded depth being over 900 m. [75] A dive normally lasts 3 to 5 minutes, but can last up to over 20 minutes.
Packard did survive and returned to diving. The story written by former Cape Cod Times reporter Doug Fraser is still, three years later, read online 300 or 400 times a month.
The unique lungs of baleen whales are built to collapse under the pressure instead of resisting the pressure which would damage the lungs, [61] enabling some, like the fin whale, to dive to a depth of −470 meters (−1,540 ft). [62]
Just another day at the office, naked deep-sea diving with beluga whales at the Arctic Circle. Natalia Avseenko, a 36-year-old Russian scientist, decided to test the hypothesis that belugas might ...
