Resumo: | The scientific cruise Observhal96 took place in August 4-27, 1996 with the underwater system for exploration and intervention « Cyana » and the support vessel « Suroît ». The goal of this IFREMER first use of a man opereted submersible for a fisheries study was to observe fishes and invertebrates in their environment, as well as fishing gears in operation. All the dives, 2 to 5 hours long, took place off Brittany in Atlantic. Five were shalower than 100 meters, nine between 100 and 200 meters, one at 400 meters and for deeper than 1000 meters.  Six dives have been dedicated to in situ study of the impact of fishing gears : observation of the geometry of a monkfish tramel net and analysis of losses during hauling ; tracks of a bottom trawl and relative efficiency trawl/submarine. A dive was aimed at geology and mineral sampling. Other dives were oriented to biological observations but whatever the main goal, all dives have brought informations on environment and species.
