Or, a sign that something's going seriously wrong with the aqua-sphere?Ath said:Another massive aquatic animal shows up out of the blue. Would be a "feather in the hat" for oceanic cryptozoology.
John Wyndham's novel, or Tennyson's poem?It vaguely reminded me of the end of 'Kraken Wakes'.
When a sperm whale dies at sea, it rots until it becomes a "skeleton suspended in a semi-liquid mass within a bag of skin and blubber," the scientists said. Eventually, the skin tears and the bones sinks while the skin and blubber float.
Boo & Hiss. I do have a pet cthuloid theory that the giant squid are taking over. Think about it, in less than one year we've had: a new species discovered, young squidlings found, reports of a population boom, and the fact that in terms of total biomass they are the planet's dominant species - surely the stars are right!JamesM said:

(Source: David Schneider, SCIENTIFIC AMERICAN, 8/97)
A strange tone is blasting through the ocean. These monochromatic signals are composed of one frequency, typically in the range of 12 cycles per second, making them purer than from any musical instrument. Individual blasts last from a few seconds to several minutes. These ocean-going sound waves -- called T waves -- were particularly cacophonous in 1991 and 1992.
Up to recently, the cause of the tones was a mystery: earthquakes produce much more short-lived signals; whales emit higher frequency sounds; harmonic tremors from magma bodies generate overtones.
The source of the tones was finally narrowed down by two French seismologists, Jacques Talandier and Emile Okal, to a poorly-surveyed region of the South Pacific. Last year, an expedition to the area revealed a flat-topped undersea volcano rising to within 400 feet of the surface. No volcanism was recorded at that time, but samples of fresh lava were recovered.
Talandier and Okal now theorize that an undersea eruption of a seamount would generate a cloud of steam bubbles sandwiched between the top of the seamount and the surface of the ocean. Computer simulations show that such a cloud would behave like a resonant cavity, acting much the same way as an organ pipe does when it sounds note. Sound waves would shoot up and down through the cloud at some resonant frequency, which was a function of the distance between the top of the seamount and the surface of the ocean. Little energy would bounce sideways, due to the diffuse boundary of the cloud. As a consequence, the fundamental frequency would remain steady and any overtones would be damped out by the gas bubbles.
