The U.S. Navy is seeking non-toxic solutions to combat barnacle infestations, which cost billions of dollars annually due to drag on ship hulls. Researchers are exploring flexible and textured coatings that may repel or deter barnacles without harming marine organisms.
Researchers have developed a new technology-driven approach to improving sea-going investigations using high-speed wireless networking. The system will enable scientists on land to analyze data immediately and provide feedback to ships at sea, reducing costs and increasing data quality.
Geologists have identified the ancient harbor of Troy by correlating sedimentary facies with ancient texts, including Strabo's Geographies. The findings will be presented at the Geological Society of America's annual meeting in Boston.
Theoretical physicists at UB have developed a system that can reduce the amplitude of physical impact by 95-98 percent, and harness dissipated energy into usable thermal energy. The research has potential applications in bridge, ship, and building protection, as well as harnessing energy from natural phenomena.
The Office of Naval Research has funded the development of a Tactical Vectoring Equipment (TVE) display, a simple array of six lights with Fresnel lenses that projects red or green light based on viewing angle. This system aims to improve navigation and communication for surface ships behind carriers in low visibility conditions.
A Smith College-sponsored expedition will retrace the original route of the Harriman Expedition, assessing ecological and societal changes in Alaska over the last century. The expedition aims to recreate E.H. Harriman's 'floating university' with leading scholars and researchers.
Researchers are surveying and identifying underwater wreckage off Utah and Omaha beaches in search of missing WWII soldiers. They've already found six to eight Sherman tanks and over two dozen wrecks.
The Knowledge Wall is an ONR-funded concept using commercial technology to display relevant data on a single wall. It was installed onboard the USS CORONADO, addressing issues faced by naval decision-makers.
The stern flap design has reduced the power required to propel Spruance and Ticonderoga-class destroyers, resulting in annual fuel savings of 3,600-4,700 barrels. The Navy plans to retrofit these ships with stern flaps, as well as Arleigh Burke and Oliver Hazard Perry classes, leading to an estimated $380 million in life cycle savings.
A new study found that two to three drinks significantly affect mariners' performance, making it twice as long to correct system failures after consuming alcohol. The researchers recommend lowering the current blood alcohol concentration limit for commercial ship personnel to mitigate this risk.
Researchers at Purdue University are designing a new generation of automated warships that can reduce naval crews by half and continue to fight with minimal maintenance. The ships will feature advanced electric power and propulsion systems, enabling automatic rerouting of power around damaged zones.
Ship emissions of nitrogen oxides can increase ozone concentrations by twofold and hydroxyl radical levels fivefold, resulting in a cooling effect on the atmosphere. This has significant implications for future international policy decisions regarding atmospheric change.
Research finds that ship sulfur emissions contribute to acid rain, damage vegetation, and form clouds over the ocean. The study highlights the importance of addressing this issue for solving part of the global climate change puzzle.
Researchers have developed a system to network up to 30 remote sensors along a single fiber optic cable, allowing for periodic assessments of structural strain. The Navy and Federal Highway Administration are exploring the use of this technology to schedule maintenance and update design codes.
A new study shows that International Maritime Organisation (IMO) rules are being applied globally, even by countries not bound to them. This shift indicates the IMO has taken on a universal law-making role, overseeing safety at sea and pollution prevention.
Seventy percent of ships use TBT-based paints, which pose a constant but low release risk. Researchers are exploring alternative antifouling technologies that can match performance while being environmentally safe.
Cargo ships powered by diesel engines are among the world's highest polluting combustion sources per ton of fuel consumed. The International Maritime Organization (IMO) has implemented new regulations to address the issue, but experts warn that a measurable reduction in nitrogen emissions will not occur for many years.
