Seafloor images collected along OFOBS profile PS153_54-1 during RV POLARSTERN cruise PS153

Year: 2026

Type: dataset

Abstract: This data was acquired during the expedition PS153 with the German ice breaker RV POLARSTERN in February-April 2026, in the western Weddell Sea, as part of the SWOS (Summer Weddell Outflow Study) project, using the AWIs towed camera system OFOBS. Aim: Assessment of macrobenthic biodiversity patterns and gradients along transects across the continental slope and across latitude in relation to environmental parameters. Deployments were planned to follow selected depth isolines if permitted by ice conditions. Station name: T3_BE1_OM, depth 2807m, drift speed 0.1-0.2kn. Comment: The laser markers are spaced 50 cm apart. The target altitude above the seafloor was 1.5 m. Additional payload: 2 NISKIN bottles for water sampling to be analysed for C/N ratio and chlorophyll a. CTD/MicroCat for direct measurements of bottom water.
