A new study provides a solutions-focused pathway to implementing the High Seas Treaty, highlighting the need for enhanced data resources and sharing. The researchers identify major scientific and technical developments that can help address challenges in biodiversity monitoring and connectivity between areas.
Cricket frogs use a combination of underwater push and leg movement to propel themselves out of the water, resulting in a 'belly flop' motion. This discovery could lead to advancements in bio-inspired robotics and water testing systems.
Historical records show manatee populations increased alongside human populations in the 1800s and 1900s. The study suggests that Florida manatees are more abundant today than any previous time in North American human history.
A UMass Amherst-led team developed biofilm-resistant glass using UV radiation, which prevents biofilm formation on surfaces in underwater environments. The technology can be used for various applications, including disinfection of transparent surfaces like windows and camera lenses.
Excavations at La Marmotta, Italy, uncovered five Neolithic canoes dating between 5700-5100BC, featuring advanced construction techniques. The discovery provides invaluable insights into early navigation and the technological sophistication of ancient communities.
A new study reveals that shipwrecks are providing a sanctuary for fish, corals, and other marine species in areas open to destructive bottom towed fishing. Marine life density is significantly higher within wreck sites than in control areas.
Researchers at the University of Texas at El Paso have developed an autonomous boat that can carry out bathymetric surveys with unprecedented ease. The robotic vessel uses a multibeam echosounder to measure water depth and detect material types on the seafloor, enabling scientists to create accurate maps of underwater terrain.
Researchers from Korea Maritime and Ocean University have developed a way to synthesize high-performance functionally graded materials with minimized defects. By controlling the mixing gradient of component materials, they improved mechanical properties and eliminated interfacial cracks.
Researchers documented traditional wooden boats in the Zanzibar Channel, showing continued use despite modern transportation developments. The study highlights innovations such as outboard engines and portable generators, which have transformed fishing methods.
Researchers at Utah State University have developed a novel design for an inflatable speedboat that utilizes elastic materials to absorb wave energy and reduce the impact on passengers. The study reveals unique differences in water-impact behavior between rigid and elastic bodies.
Research by James Rodgers and Stephen Schwikert found that flush distances for motorboats were greater than those for personal watercraft (PWC), allowing for more effective protection of waterbirds. The study recommends customized buffer zones to protect vulnerable species, such as great white herons.
A Penn State study found that uniform speed limits can lead to different impacts on boats of different sizes. At speeds near 6-8 mph, prop wash can stir up lake sediments, aggravating turbulence problems. The study suggests a computer program to predict water velocity and guide lake managers in setting safe speeds.
