Carnegie Mellon navigation, mapping software passes Mexican field testPITTSBURGH -- An underwater robot, shaped like a flattened orange, maneuvered untethered and autonomously within a 115-meter-deep sinkhole during tests this month in Mexico, a prelude to its mission to probe the mysterious nether reaches of the world's deepest sinkhole. Bill Stone, leader of the NASA-funded Deep Phreatic Thermal Explorer (DEPTHX) mission, said the 2.5-meter-diameter vehicle performed "phenomenally...
By Bradbeer, Robin S; Ku, Kenneth K K; Yeung, Lam F Camera Operates With Low-Disturbance to the Environment of an Inshore Coral Reef The most common methodology for monitoring fish activity on coral reefs is to use scuba divers. Several articles have been published in mis area. However, any form of human intervention can be damaging to the reef, especially in areas where the habitat is under threat. This is especially the case where inexperienced divers are involved. The work for the...
NEW YORK -- Contrary to some reports, scuba divers do not appear to have an accelerated decline in lung function, according to researchers at the German Naval Institute."Obstructive changes in lung function have been reported with cumulative scuba diving exposure," Dr. Kay Tetzlaff, of the University of Tuebingen, and colleagues write in the medical journal Chest.To look into this, the researchers studied in 468 military scuba divers and a comparison 'control' group of 122 military...
DAR ES SALAAM (Reuters) - The prospect of rescuing four Danish tourists and their Canadian scuba diving instructor who went missing four days ago off Zanzibar is diminishing, the local divers' club said on Wednesday. The five left with another group for a diving course on Saturday and were last seen under water near Pemba Island on the east African coast. A statement by Swahili Divers said they were still searching for the five. But "we appreciate that after being missing for four days the...
WASHINGTON (AP) -- Sperm whales routinely dive more than two miles below the ocean surface to hunt for giant squid, but a study shows the huge mammals suffer a chronic loss of bone tissue from the bends, a painful condition well-known to human divers. It has long been believed that sperm whales and other deep-diving mammals are immune from decompression illness, or the bends, which human divers encounter when they surface too rapidly and force nitrogen bubbles into their blood and tissues....

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...
