This is a snapshot of the output data created by the Side Scan Sonar Towfish. It was charted by the Gelendzhik on behalf of Tyco Telecommunications recently during the survey off Madang. The object at 100m out from the vessel is most likely a shipwreck, measuring approximately 70m long. The waters around Madang conceal many World War II-era ships and aircraft wrecks. It’s possible that this is such a wreck. Click on the photo to enlarge.
