Leatherback turtles are remarkably versatile divers. Routinely diving to depths of several hundred meters, leatherbacks are occasionally known to plunge as deep as 1250m. The animals probably plumb the depths to avoid predators, search for prey and avoid heat in the tropics. However it wasn't clear how these mammoth reptiles regulate their buoyancy as they plunge down. Sabrina Fossette from Swansea University explains that no one knew how the turtles descended so far: do they swim down or...

PHILADELPHIA, July 30 /PRNewswire-USNewswire/ -- Duck boats in the Ride the Ducks Philadelphia fleet do not have sufficient reserve buoyancy to remain afloat in the event of flooding and have canopies which are well known to cage passengers attempting to escape. As a result, attorneys for Dora Schwendtner and Szabolcs Prem and their families are urging the City of Philadelphia and the U.S. Coast Guard to immediately impose a moratorium on all duck boat service on the Delaware River. Dora...

As you go about your day-to-day activities, tiny bubbles of nitrogen come and go inside your tissues. This is not a problem unless you happen to experience large changes in ambient pressure, such as those encountered by scuba divers and astronauts. During large, fast pressure drops, these bubbles can grow and lead to decompression sickness, popularly known as "the bends." A study in the Journal of Chemical Physics, which is published by the American Institute of Physics (AIP), may provide a...

Surface Weather Map Features for July 5, 2012
2012-07-05 10:00:03

The morning weather map for July 5, shows us the current surface pressure readings. Surface Pressure is very important from a meteorological stand point. We use this to help us identify where our surface pressure centers are just like you see above. Our Low pressure area is over Northeast Colorado and also the High pressure over the Ontario area. Surface pressure is taken hourly from the stations and they are also mostly done on a 24hr basis, however some places will only submit their...

A wetsuit, worn by divers, windsurfers, and others engaged in water sports, is a garment, made of foamed neoprene that provides thermal insulation, abrasion resistance, and buoyancy. The suit provides insulation through bubbles of gas enclosed within the material which reduces its ability to conduct heat. These bubbles also provide buoyancy in water. Contrary to popular belief the layer of warm water trapped between the suit and the skin provides very little thermal insulation. Wetsuits...

A barometer is an instrument that measures atmospheric pressure. The barometer measures pressure exerted by the atmosphere using water, air, or mercury. Through measuring the pressure one can forecast short term weather changes. Evangelista Torricelli is credited with the invention of the barometer in 1643. However, Gasparo Berti unintentionally built a water barometer around the same time. Rene Descartes was also noted as describing an experiment to determine air pressure but there is no...
