Spectacular Images of WW2 Wrecks

  18/05/2010
StarFish 450F, the shallow water sidescan sonar system from Tritech International, recently completed the successful deployment of a wreck dive in the low-visibility waters of Conception Bay off Canada's Atlantic Coast. The sonar was able to operate at low-range, enabling the wreck team from Ocean Quest Adventure Resort (OCAR) to collect details of World War II (WW2) ships, SS Rose Castle and PLM-27, which were hit simultaneously and sunk by a German U-Boat during the war.


Spectacular Images of WW2 Wrecks StarFish was able to clearly scan the wreck of SS Rose Castle where visible structures, as identified in the scan images, included rigging, substructures and cargo holds. At approximately 160 feet deep, this wreck is the deeper of the two wrecks scanned by the OCAR team in Conception Bay.


Encouraged by the scans obtained from the SS Rose Castle, OCAR continued with a second wreck dive to the PLM-27. Lying in much shallower waters, the PLM-27 is sunk at 100 feet of water with only 50 feet to the deck. Again, from the spectacular sonar images produced by StarFish 450F, substructures such as the stern gun, torpedo hole, the derricks and the cargo hold were all clearly visible.


StarFish 450F is a plug-and-play side scan, powered from any source and comes complete with user-friendly StarFish Scanline software. OCAR was impressed with StarFish 450F's capabilities and indeed its ease in usability which allowed the team to complete both wreck dives in under one-and-a-half hours.
Andrew Hiscock, Wreck Booking Co-ordinator, OCAR comments on the different outlook StarFish gave their wreck dive: "We got amazing shots of both the wrecks from the StarFish 450F system and the scan of the PLM-27 could almost be used a map to navigate around the 400 foot wreck. After diving these wrecks for twelve years, it was great to see them from a completely different perspective."

MCA on Surveying the British Coast

Rob Spillard explains how the MCA is conducting hydrographic surveys, including the history of British hydrographic surveying, latest developments in technology and wreck research projects, sometimes accompanied by a BBC TV camera crew. This movie includes an example of the discovery of two sunken WWI submarines off the Orkney Islands.
