Robot sub beats nets for discovering what lurks at the bottom of the sea

Curious about what's living on the deep sea floor? Well, the Autosub6000 AUV (autonomous underwater vehicle) is helping us find out. Led by Dr. Kirsty Morris, a team at the UK's National Oceanography Centre (NOC) has equipped one of the unmanned submarines with a high-resolution photographic system. As a result, it's claimed to be far more effective at identifying deep-sea life than the usual approach of scientific trawling. Read More

Autonomous underwater vehicle looks for algae on underside of ice

Early every spring in Antarctica, mats of algae form on the underside of the sea ice. These mats – along with bacteria that live in them – serve as a food source for zooplankton, essentially kickstarting the food chain for the year. Given that the ice algae plays such an important ecological role, scientists from Denmark's Aarhus University have set out to better understand its distribution. In order to do so, they're using a high-tech underwater drone. Read More

Study finds early warning signals of global ocean conveyor belt collapse

We could see early warning signs of the collapse of a key component of the global climate up to 250 years in advance, a new study has shown – ample time to either prevent or prepare for the consequences of abrupt climate change. The University of Exeter study analyzed the Atlantic Meridional Overturning Circulation (AMOC), sometimes referred to as the global ocean conveyor belt, in a highly-complex and realistic simulation model, and identified the likely mechanisms that would drive such a collapse.Read More

Ocean gliding robots used to study melting Antarctic sheet ice

The use of "ocean gliders" for conducting research in oceanic conditions not ideal for regular methods has been catching on in the scientific community. Examples of this have been seen in the detection of endangered whales in the North Atlantic and a study of the Atlantic sturgeon. Researchers have now turned their robotic ocean helpers towards Antarctica, to study the rapidly-melting ice sheets on the coast of the western part of that polar land mass. Read More

Rower prepares to cross the Atlantic in futuristic boat

Like many fathers with young children, experienced rower Andras Bakos is concerned about what sort of shape the environment will be in by the time his son grows up. That's why in 2011, he began planning a trans-Atlantic rowing expedition to raise awareness of environmental issues. The boat that he had custom-built for the trip is now ready to go, and it looks like it could just as well be used for rowing to Mars.Read More

New map shows world's seafloor in unprecedented detail

Given they aren't covered by oceans, it's maybe not so surprising that we know more about the topography of the Moon and Mars than we do about Earth's ocean depths. But researchers have evened the score at least a little with the creation of a new map of the world's seafloor. Twice as accurate as the previous version produced almost 20 years ago, the new map details thousands of previously uncharted mountains and provides new clues on the formation of the continents.Read More

New discovery could pave the way for glues that stick like barnacles

If you place pretty much any type of solid material in the ocean, barnacles will firmly attach themselves to it. If you were to try applying a glue to any of those materials while they were underwater, however, it likely wouldn't stick. So, what do barnacles know that we don't? Scientists have recently discovered the answer, and it could lead to advances in human technologies. Read More
