An underwater robot has enabled researchers to produce the first detailed, high-resolution 3-D maps of Antarctic sea ice. Scientists from the UK, USA and Australia say the new technology provides accurate ice thickness measurements from areas that were previously too difficult to access. Scientists use a range of technologies and techniques to measure sea ice […]
In the last 60 years the fishing industry have caught nine out of every ten large fish. That’s only 10% of large fish like tuna, cod, swordfish and halibut remaining on the planet. International fleets still pursue what is remaining. According a 2014 report by the United Nations Food and Agriculture Organization, over 90% of […]
Ahmed Gabr has made the deepest ever scuba dive—to 332.35 meters—in Dahab in Egypt. The dive was projected to take 14 hours to complete, with just minutes of this being the descent time. Gabr and his support divers team planned to use about 90 tanks (plus 17 twinsets) in the course of the dive. His […]
This year an array of sensors are watching for harmful red tides in the Gulf of Maine. Red tides are toxic and can cause paralytic shellfish poisoning.
Students win $1000 to advance their process by which oxygen and nitrogen can be harnessed in solid form and used by SCUBA divers.
With the help of the Catlin Seaview Survey, Google has added more underwater locations to its “Street View“. Google put the first marine images up in September 2012, with dives in Australia, the Philippines and Hawaii. Now it covers 16 more countries, including the Galapagos, Monaco, Bermuda and Mexico. It really is a fantastic way […]
The devastating tsunami that struck Japan’s Tohoku region in March 2011 was touched off by a submarine earthquake far more massive than anything geologists had expected in that zone. Now, a team of scientists has published a set of studies in the journal Science that shed light on what caused the dramatic displacement of the […]
Scientists and engineers have achieved the first step in developing a cost-effective micro sensor for long-term monitoring of ocean acidification. The new technology, that will measure pH levels in seawater, was developed by engineers from the National Oceanography Centre, in close collaboration with oceanographers from University of Southampton Ocean and Earth Science, which is based […]
You don’t usually find a wireless network whilst underwater, but that may change as researchers develop a deep-sea internet
The Trident underwater robot has been able to find and retrieve independently an object in an unknown seabed facing the adverse conditions presented by the open ocean. The I-AUV (autonomous underwater vehicle for intervention) has been successfully tested in the Port of Sóller, Mallorca. Designed for multipurpose submarine intervention tasks like underwater archaeology, oceanography and […]
