Abstract | The main goal of the M37/1 was to sample sedimentary deposits along a series of transects from the shelf off Morocco to the open ocean. This goal was achieved by the quantification of the influence of the coastal upwelling and the Saharan dust on particle fluxes in the Canary region and the investigation of its change through the last glacial and interglacial periods. During the entire cruise, the Hydrosweep was used on a 24 hour schedule one day after leaving the 200 sm zone of Portugal to record continuous high resolution bathymetric profiles. Rough sea bottom topography and bad weather conditions caused problems with the system, the data processing of the multibearn sounder often resulted in gaps. Otherwise the system performed as expected. |
