Purpose
Abstract The cruise M37-2 was aimed at studying the circulation and transports of water masses, the associated fluxes of bio-geochemical parameters in the water column and through the air sea surface in this area and their variability in space and time in the area north of the Canary Islands. This research was done to obtain an improved knowledge of the physical processes controlling the subtrobical gyre and the related mesoscale circulation through observations and circulation models. 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
