Purpose | |
Abstract | The main focus of the cruise M114 was the investigation of seafloor structures, which are related to asphalt deposits on top of submarine ridges and knolls, known as salt diapirs. The EM122 was recording constantly within the permitted areas, either designated to bathymetry surveys or flare imaging-surveys. It was running without any problems with regard to hardware or software during the whole cruise. The weather and sea state was mostly cooperative. Nevertheless, the data quality deteriorated due to higher winds and sea states at a few days during the cruise. |
