Purpose | |
Abstract | The main goals of cruise M81/2AB were to combine geological and geophysical research methods in order to gain new insights into 1) the origin, evolution and composition of the Caribbean LIP and 2) the geodynamic evolution of the Central Caribbean. We were able to conduct our planned research in Colombian waters during Leg 2B. ROV dives, dredge hauls, and magnetic profiling were always accompanied by multi-beam mapping (SIMRAD EM120) and sediment echosounding (ATLAS PARASOUND) to get information about the morphological structure of the sea floor and the sedimentary layering in flat areas. |
