ObjectivesDuring the expedition IceAGE2 three transects were sampled. The first transect started in the northern North Sea and ended in the Norwegian Sea sampling the Norwegian Channel in 200m steps in depths between 200 and 1800m. The second transect crossed the Faroe-Scotland Ridge sampling on top of the ridge east of the Faroe islands and south east of the Faroe Islands. The third transect crossed the Iceland-Faroe Ridge. Transects over the ridge structures aim to detect potential barriers of species distribution due to the ridge and the hydrographic differences (oceanography) north and south of the ridge. The working area in the Norwegian Channel was characterised by a steep slope decreasing from relatively shallow areas (200-500m) to large depth (1000m) with the steepest part between 600-800m depth. In the Norwegian Channel the aim was to detect where the faunal change from North Sea fauna to Arctic fauna takes place. The transect over the Iceland-Faroe Ridge is characterised by a complicated hydrography and fast changing water masses as well as strong currents on a rocky bottom. The mountain chain underwater is not completely mapped and the seafloor charts are incomplete. Most of the depths in the charts were not precise enough to know the precise depth of the station sampled before arriving at the point.
