| Purpose | |
| Abstract | The main objective of the cruise M95 was to establish spatially and temporally high-resolving reconstructions of the Late Pleistocene surface,subsurface and intermediate water variability, in relation to the Loop Current variations and related eddy shedding, Antarctic Intermediate Water migrations, and changes in the Atlantic Meridional Overturning Circulation. Bathymetric measurements have been carried out mainly with the hull mounted EM122 swath sounder. A swath of 256 preformed beams is emitted periodically with signal frequencies of 12 kHz.Though multibeam data was recorded, it was not the main focus of the cruise and no further information have been provided by the responsible party. |
