Purpose
Abstract The first two legs of M16 were part of the SFB 261 of Bremen University with the aim of collecting data and sample material from the equatorial Atlantic to investigate the relations between climate changes and the water circulation in the Atlantic as well as the bio productivity. During the second leg sediments were collected in the Ceara Rise and off the Amazonas Delta. This material was studied using chemical and magnetic methods. Additionally seismic survey were a part of the scientific program. During the entire cruise Hydrosweep Data were collected- The quality of profiles varies coherent to weather conditions and ship course. 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.
