    DEEP SEA DETECTIVES: MYSTERY U-BOAT OF WORLD WAR I
    A veteran of the brutal naval battles of World War I, the German submarine UB-107 was discovered on the floor of the North Sea in 1985. An important find itself, it harbored a surprise that would force experts to re-examine the records of the epic conflict. Join John Chatterton and the DEEP SEA DETECTIVES as they descend 100 feet into cold and murky waters to explore this remarkable site. Entwined in the remains of the submarine is the wreck of the British steamship Malvina, which was supposedly sunk a week after the UB-107, and thirty miles away! Historians and divers help piece together the clues left behind by these ghosts of World War I.

    Truth Duty Valour



    Published on Aug 17, 2016
    Submarines are one of the most capable and cost-effective ways a nation can assert sovereignty over their waterways. Truth Duty Valour travels to the frigid waters off Norway to spend ten days underwater with the crew of H.M.C.S. Corner Brook as they train the commanders of tomorrow! From covert intelligence gathering to evasive operations, we learn what it takes to be a submariner. Submariners rule the waves!

    UNDERWATER EXPLOSIVES & ANTI-SUBMARINE WARFARE U.S. NAVY FILM "CLOSE IS NEAR ENOUGH" 52084
    PeriscopeFilm



    Published on Feb 16, 2017
    This “unclassified” 1974 US Navy film opens with a German submarine crew silently stalking and then firing upon an Allied vessel. During WW2, the film says, 47 major ships, 52 submarines, and countless lives were lost. The war also taught the Navy that close exposure to an underwater blast can severely damage a ship’s hull or propulsion systems, putting it out of commission. The film’s title, “Close Is Near Enough,” appears on the screen at mark 03:20 as the narrator echoes those same words. For this reason, the Navy established the Underwater Explosions Research Division (UERD) in 1946 to find way to strengthen ships’ hulls. The film shows footage of ships earmarked for the scrapyard being torpedoed as part of the test process before explaining what happens to a vessel during an underwater explosion (mark 04:45). We watch as a highly compressed gas bubble pulsates before creating a series of water plumes above the water line. The bubble causes severe pressure on any nearby object with the shockwave damaging a ship, even lift it into the air and slamming it back into the water. The film shows high-speed cameras being fitted into test ships to film damage (mark 07:30) with the captured footage shown and the details later analyzed (mark 11:00). The information ultimately will be used for new design techniques. There is a look of the UERD’s Submarine Shock Simulation Vehicle to evaluate the strength of submarines (mark 12:00) with additional footage of tests conducted using the vehicle as well as other ship explosions (mark 15:57) and experiments using simulated underwater mines (mark 18:00).

    We encourage viewers to add comments and, especially, to provide additional information about our videos by adding a comment! See something interesting? Tell people what it is and what they can see by writing something for example: "01:00:12:00 -- President Roosevelt is seen meeting with Winston Churchill at the Quebec Conference."
