When the World War II-era German battleship Bismark was found in 1989 about 15,700 feet down, the impact of hitting the ocean floor drove the bottom deck up about one level into the vessel, and compressing water inside the ship blew out plating on its hull, Sean Kery, a hydrodynamicist who co-chairs a marine forensic committee for the Society of Naval Architects and Marine Engineering, told The Florida Times-Union (http://bit.ly/1Ohn0Wy).
He was a hydrodynamicist in the Fluid Mechanics Group, Lockheed Missiles and Space Co., (1989 - 1994), responsible for hydrodynamic analysis of cavitation and super-cavitation during the underwater launch of the Trident missiles.
As a hydrodynamicist, he was among the first to develop a numerical code for ocean wave diffraction around large objects in the sea.
