In February 1994, during the SAMBA 1 cruise, 9 CTD casts were done and 22 subsurface floats (20 MARVOR, 1 VCM, 1 ALFOS) launched near 800 dbar in the Brazil basin, within the framework of the SAMBA Experiment. SAMBA (SubAntartic Motions in the Brazil bAsin), is a component of the WOCE float program, and aims at describing the absolute general circulation of the Antarctic Intermediate Water around 800 m depth in the Brazil basin. MARVOR and ALFOS floats cycle every 2 months between thier nominal depth and surface to transmit data via the ARGOS system and were programmed for 30 cycles, i.e. a total life of 5 years. THE VCM float, on the other hand is a one shot RAFOS-type float which was programmed for a 1.5 year mission at depth. This report presents the hydrographic data and the first 18 months of float data obtained so far.
