Getting to the Bottom of the Navies' Mine Warfare Challenges

To find the mine warfare challenge with the highest degree of difficulty, start at the bottom.Lurking unseen below the surface, naval mines pose a serious problem. They’re cheap, relatively easy to deploy and can inflict heavy damage against even the most sophisticated warships. They can be hard to detect and difficult to counter. What you can’t see can hurt you. And the most difficult mines to find and eliminate are bottom and buried mines.

US Coast Guard Cutter Healy, Scientists Deploy Ice Stations

U.S. Coast Guard Cutter Healy (WAGB 20) crew and embarked researchers ventured onto a floe of multi-year ice for the first of three multi-instrument ice stations in the Arctic Ocean Basin late July and early August.As the Healy carefully approached and maintained position alongside an ice floe above 77 degrees north, the crew and a team of scientists, working in cooperation with the Office of Naval Research…

Subsea Vehicles: A Journey to the Under – and Outer – Worlds

It’s often remarked upon that we know more about the surface of the moon than we do the depths of our ocean. Scientists are now shooting for both – and beyond.
