Purpose
Abstract As a part of the project SFB 261 (university of Bremen) the research interest of M41/1 was the sampling of sediment and water to measure benthic 02 and CO2- fluxes as well as to observe the distribution of dinoflagellates. Therefore a multicorer and a rosette sampling system were used. During the entire cruise Hydrosweep and Parasound Data were collected. The used Hydrosweep is a multibeam echosounder using a frequency of 15.5 kHz. 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.
