Scuba News ..because we can’t be underwater all the time Stressed seaweed contributes to cloudy coastal skies May 16th, 2008 A new international study has found that large brown seaweeds, when under stress, release large quantities of inorganic iodine into the coastal atmosphere, where it may contribute to cloud formation. Posted in Diving | Comments Off Pilot whales are the sprinters of the deep May 15th, 2008 Pilot whales are the cheetahs of the oceans, focusing their hunting effort on short, intense chases after a few rich food items. They are the first deep-diving whales known to follow such a strategy. Until now, biologists had assumed that all deep-diving whales would cruise slowly and graze on slow-moving prey items while underwater, since this minimises their energy expenditure. Using this strategy, most deep-diving whales can spend nearly an hour at a time underwater. Pilot whales, however, are the exception - their dives last no more than 15 to 20 minutes. "They look like they are going after big, nutritionally rich prey."

Posted in Diving | Comments Off Google dives into 3D mapping of oceans May 12th, 2008 We've got Google Earth and Google Sky. Next up will be a map of the world below sea level--Google Ocean. The company has assembled an advisory group of oceanography experts, and in December invited researchers from institutions around the world to the Mountain View, Calif., Googleplex. There, they discussed plans for creating a 3D oceanographic map. The tool--for now called Google Ocean, the sources say, though that name could change--is expected to be similar to other 3D online mapping applications. People will be able to see the underwater topography, called bathymetry; search for particular spots or attractions; and navigate through the digital environment by zooming and panning.
