    Interference fringes on GLORIA side-scan sonar images from the Bering Sea and their implications

    GLORIA side-scan sonographs from the Bering Sea Basin show a complex pattern of interference fringes sub-parallel to the ship's track. Surveys along the same trackline made in 1986 and 1987 show nearly identic...
