Long-duration unmanned surface vehicles manufacturer Liquid Robotics has rolled out its next generation Wave Glider, featuring advancements to the platform’s operational range, and performance for missions in high sea states and high latitudes. Other updates include advancements for expanded sensor payloads and increased energy and storage capacity required for long duration maritime surveillance, environmental monitoring and observation missions.
Researchers in Switzerland have developed a 4-foot-long pollution-tracking robotic water snake. The "Envirobot" comprises several special-purpose modules, which constitute it's eel-like design, according to a press release on the l'cole polytechnique fdrale de Lausanne website. The purpose of the modules are twofold. First, each has a small electric motor that lets the robot swim like a water snake. Secondly, each segment has a unique sensor for gathering different data and measurements. More modules can be added as needed.
HALF MOON BAY, CALIFORNIA – While waves that once a year become the monster swells ridden by surfers in the Mavericks surf contest roll toward the harbor of this small fishing town south of San Francisco, oceanographer Tim Janssen sits in an office a block from the sea with a handful of colleagues and two dogs. They’re working on a small sensor-laden device he hopes to deploy by the thousands to gather data on those waves and other ocean conditions. Called the Spotter, the yellow space capsule-shaped float is about the size of a beach ball. Solar panels keep its batteries charged and the data gathered by its sensors is beamed via satellite to scientists’ laptops and smartphones. The Spotter is part of an explosion of new, cheaper tools for oceanographic research, giving scientists access to more real-time data about the ocean.
HUNDREDS OF THOUSANDS of fishing vessels. Millions of square miles of ocean. Billions of radio transmissions. The constant stream of data can overwhelm even the most dedicated fisheries managers trying to combat the $23 billion illegal fishing industry. In economically underdeveloped countries, a small team of analysts must pore over the surveillance profiles of thousands of fishing enterprises; often the environmental cops can be as much as six months behind. By the time they see that a vessel in their jurisdiction is acting suspiciously, the ship has sailed.
Vivid, detailed maps created during the unsuccessful hunt for MH370 have been published by investigators to shed light on the depths of remote and previously unexplored parts of the ocean. The maps reveal the location and scale of under-sea volcanoes, ridges, mountains and shipwrecks found on the floor of the Indian Ocean. A painstaking two-year search of the sea bed ended in January without finding the Malaysia Airlines Boeing 777, which vanished in March 2014 en route to Beijing from Kuala Lumpur with 239 people on board.
Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of 15 marine scientists, resource economists and legal scholars argue in a letter published today in the journal Nature Geoscience.
Last year's devastating category-5 hurricane -- Matthew -- may be one of many past examples of a tropical storm fueled by massive rings of warm water that exist in the upper reaches of the Caribbean Sea.
Controls engineers at UC San Diego have developed practical strategies for building and coordinating scores of sensor-laden balloons within hurricanes. Using onboard GPS and cellphone-grade sensors, each drifting balloon becomes part of a "swarm'' of robotic vehicles, which can periodically report, via satellite uplink, their position, the local temperature, pressure, humidity and wind velocity. This new, comparatively low-cost sensing strategy promises to provide much-needed in situ sampling of environmental conditions for a longer range of time and from many vantage points within developing hurricanes.
Prior to the release of the fiscal 2017 budget, Defense Secretary Ash Carter announced in front of a group of sailors aboard the USS Princeton aircraft carrier in San Diego in February that the Defense Department would be investing $600 million in undersea systems over the next half decade. Raytheon is jumping on this bandwagon in addition to developing more scalable littoral radar systems for future platforms. With the increased concern emanating predominantly out of Russia and China, threatening the U.S. ability to maintain undersea dominance, the company is investing heavily in this area to bring new capabilities to bear, said Paul Ferraro, vice president of Seapower Capability Systems at Raytheon.
While climate change threatens coral reefs in oceans around the world, not all reefs are affected equally. As oceans warm, physical forces like wave strength and water flow influence which reefs thrive and which die, according to a study led by Justin Rogers, a postdoctoral researcher at Stanford's Environmental Fluid Mechanics Laboratory.
Seismologists in Japan have tracked, for the first time, a particular type of tiny vibration that wobbled through the Earth from the Atlantic seafloor. It was started by a "weather bomb": the same low-pressure storm, off Greenland, which made UK headlines in late 2014.
Ocearch said its team of fishermen and scientists has found the first known birthing site for great white sharks on the North Atlantic Coast. After 26 expeditions, Ocearch said the birthing site in the famous waters off Montauk, Long Island is the most significant discovery they’ve ever made, reports CBS News correspondent Jeff Glor. As soon as the shark slides onto the lift, scientists and researchers rush in. By now, the process of tagging is routine for Ocearch. But the particular goal of this trip is not.
