3D spatial imagery in the search of MH370
The MH370 search area encompasses the seabed on and around Broken Ridge, an extensive linear, mountainous sea floor structure that once formed the margin between two geological plates. These plates spread apart between 20 and 100 million years ago, under similar processes found today at spreading plate margins such as the Mid-Atlantic Ridge.
The sea floor around Broken Ridge still retains many of the large geological structures typical of spreading plate margins where volcanism and tectonic movements produce volcanoes (now extinct), high rugged ridges and deep trenches.
The recently acquired high-resolution bathymetry data has revealed many of these seabed features for the first time. It is also revealing finer-scale seabed features that were not visible in the previous low-resolution, satellite-derived bathymetry data.
