Objective Geophysical recognition mission of the Southeast Greenland Margin. The cruise, consisting of three legs (CEPAN CH60, CEPAN CH61 and CEPAN CH62) was limited to the Jan Mayen Ridge and its southern extension. It includes 5,015 km of 24-channel seismic reflection profiles with an IFP Flexichoc source, established from the RV J. CHARCOT of CNEXO (currently IFREMER). About 2,500Km of these profiles were processed and the bathymetry and magnetic field were continuously recorded. The survey had a double objective. Firstly, it was to confirm the existence of a sedimentary series already observed during previous investigations. Secondly, it was planned to examine the tectonic style of the Jan Mayen Ridge in relation to the spreading of the ocean basins to the east and west.
