英文简介	Imagery transects with a camera attached to a multibox corer providing seabed images were carried out during POLARSTERN expedition ANT-XXIX/9 (PS82) focussing on the ecology of benthic assemblages on the southern and eastern Weddell Sea shelves. The camera system attached to the multibox corer was composed of one casing housing a Cannon EOS 100 camera, a second casing housing a flash-light, two lights fixed to the multibox corer frame, and 4.5cm distanced parallel lasers providing a scale in the images. The camera was tilted to a 45° angle. The transects were done along the drift trail of the ship, maximum speed was 1knot, and minimum speed varied with current speed. The winch of the ship was used to maintain a distance of approximately 1-2m above the seabed.
