Getting Metal Wet: Mocean Energy's Wave Energy Device Arrives in Orkney Ahead of Sea Trials

EMEC over the coming months. The staged approach which has been followed to develop the Blue X device through the WES program will be continued as it is firstly put through its paces at our smaller-scale, ‘gentler’ test site in Scapa Flow, prior to being subjected to the full force of the Atlantic Ocean at Billia Croo."Getting metal wet and testing technologies for prolonged periods is vital to prove performance, reliability, and survivability, as well as how to install, operate, maintain and decommission such structures. With more technologies tested here in Orkney than anywhere else in

To probe the ocean’s opaque interior, sound is one of the most efficient tools available. WHOI scientists have developed an “acoustic telescope” to “see” into a noisy ocean and pick out unique sounds produced by distant acoustic phenomena, such as whale calls and fish schooling, as well as the rumble of earthquakes, volcanoes, and storms© Woods Hole Oceanographic Institution, N.

A Net-zero Future Depends on the Ocean’s Ability to Absorb Carbon

(the tiny plants and animals that feed everything from mussels to whales) store carbon, so their behaviour and biology become a critical factor in the climate discussion.We urgently need better observations of the ocean’s continued role as our heat and carbon sink.Shifting carbon sinkThe North Atlantic Ocean is the most intense carbon sink in the world: 30 per cent of the global ocean’s carbon dioxide removal occurs right in Canada’s backyard. If we extend Canada’s net-zero calculation to our exclusive economic zone (waters within 200 nautical miles of our coast), our net carbon

Trash Traps to Be Installed in St. Louis Streams

as an ideal location to launch the pilot project to study trash and litter, as it sits on the confluence of the two most prominent American rivers, the Mississippi and Missouri. Their watersheds combined form the largest single watershed in the United States and flow south to the Gulf of Mexico and Atlantic Ocean.“The debris and trash that enters these two watersheds often makes its way through storm sewers and remains hidden until storms and rain empty the debris from storm sewers into small streams and larger rivers,” Robichaud said. “This is a positive step in helping to keep River

Ireland’s New Research Vessel to Be Named Tom Crean

energy, marine spatial planning, marine protected areas and addressing the challenges of climate change," McConalogue said.The new marine research vessel will provide a year round service for expanded fisheries surveys, seabed mapping, deep water surveys and support increased research in the Atlantic Ocean. The new vessel will enable 300 operational days at sea each year, and up to 3000 scientist days per year. The new vessel will also enable the Marine Institute to continue to lead and support scientific, high quality surveys that contribute to Ireland's position as a leader in marine science

Doug’s spark of inquisitiveness and creativity is contagious, and we strive to follow the advice that he gave to Rutgers students after the first Slocum glider Atlantic Ocean crossing – 'Work hard, have fun, and change the world',” said Clayton Jones, Senior Director of Technology, Teledyne Marin

New Study Finds Polyester Fibers Throughout the Arctic Ocean

microplastic particles per cubic meter of seawater throughout the Arctic, illustrating just how widespread synthetic plastic pollution has become in this remote region. This is lower than concentrations found in more urbanized regions in the South, but approaching levels found in the open Pacific and Atlantic Oceans.Of these, 92 per cent were fibers, averaging 14 microns (0.014 mm) thick and 1,100 microns (1.1 mm) long. We documented every colour imaginable: red, blue, yellow, green…. But perhaps the most striking finding in the lab was that 73 per cent of these fibers were polyester.Tracking the

U.S. DOE Grants $21M for Offshore Wind Tech Projects

offshore wind platform capable of supporting a 10+ megawatt turbine, using a scale model testing and simulation methodology previously used for oil and gas floating production facilities. The design is planned for installation and grid connection at one of Mayflower Wind’s lease areas in the Atlantic Ocean.The University of Maine will design, demonstrate, and validate a synthetic rope mooring for floating offshore wind turbines, which is expected to reduce the impact of offshore wind development on commercial fishing and reduce costs. The mooring system will be demonstrated on a full-scale floating
