It was in the oceans that life first evolved and where complex animals have thrived for over 600 million years. Marine animals survive in environments as diverse as tropical coral reefs, polar ice-capped oceans, and the lightless abyssal depths, says Frank E. Fish from West Chester University and Donna M. …

Currently, the most widely used technology to detect underwater objects  is sound navigation and ranging (SONAR), because acoustic waves can  penetrate the water depths to the bottom of the sea. SONAR also suffers from unwanted multipass echoes that are due to reflections from the surrounding terrain. Thus, high-resolution underwater imaging …

Unmanned aircraft systems (UAS), which are going through a massive development phase, are finding their purpose in the shipping industry as well. In the shipping industry, drones have typically been used for security, environmental surveillance, emergency response, search and rescue missions, as well as various vessel inspections. Now Shipping companies …

China has boosted its submarine force over the last 20 years, building a modern, flexible force that now has more total ships than the US. The force currently numbers 56 subs – four nuclear-powered missile subs, five nuclear-powered attack subs, and 47 diesel-powered attack subs – and is likely grow …

In 2000, a Russian cruise-missile submarine — Kursk — sank, killing all 118 sailors on board. The Russian government concluded the ship sunk due to a faulty weld which caused a gas leak and led to an explosion.   The U.S. Navy in August 2018 said that there’s a problem …
