Abstract | The objective of SO197 was to study the rift structures and the continent-ocean transition at the southeastern border of the South China Sea in time and space with the final goal to derive a model that explains the structures and the mode of extension. The second objective that has a close relation to the first purpose is a detailed reconstruction of the opening history of the South China Sea oceanic basin. Bathymetric mapping has been conducted continuously. The SIMRAD EM120 operated throughout the cruise without interruption. Data quality was generally good to excellent. The reduced ship speed of 5.4 kn provided optimal data acquisition conditions in combination with the perfect sea conditions. The operational parameters used during the cruise leg have been: no tide correction, equidistant beam coverage, automatic sounding mode and fan coverage, sound velocity at ships keel from ships sensor. Beam angles and across track distance were fixed to 62° and 13000 m, respectively. |
