False killer whales focus echolocation clicks Hunting in the ocean's murky depths, vision is of little use, so toothed whales and dolphins (odontocetes) rely on echolocation to locate tasty morsels with incredible precision. Laura Kloepper from the University of Hawaii, USA, explains that odontocetes produce their distinctive echolocation clicks in nasal structures in the forehead and broadcast them through a fat-filled acoustic lens, called the melon. 'Studies by other people showed...

Tracking fish across Alaska's vast continental shelves can present a challenge to any scientist studying Alaska's seas. Researchers at the University of Alaska Fairbanks have successfully tested a possible solution in the form of underwater gliders. Last month, Peter Winsor, associate professor of physical oceanography, and Andrew Seitz, assistant professor of fisheries, tested the use of autonomous underwater vehicles, called gliders, for tracking tagged fish. Winsor and Seitz suspended...

Scientists from the Naval Research Laboratory at Stennis Space Center, MS, (NRL-SSC) and Washington, D.C., recently completed an investigation of the acoustic properties of the deep seafloor in the Gulf of Mexico. Scientists on the cruise measured the effects of geologic faulting on the efficiency of acoustic wave propagation. "Knowing the bottom loss-the amount of sound energy lost with each bounce off the bottom-affects how far away one can 'see' a target in the ocean using sound," said...

Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
