3D models of the Antarctic seafloor were created with the software PhotoModeler Scanner (v.2012.0.0.586) based on 2D video data from a ROV (Sperre SubFighter 7500 DC, Sven Loven Centre for Marine Sciences, University of Gothenburg, Sweden) dive at station PS77/253-1 (video doi:10.1594/PANGAEA.804857) and a reference scale (laser projections, 5cm apart).These models were then used to compute subtransects lengths.Here we provide information about those subtransects obtained from the 3D models along with the models themselves:- zipped Photomodeler project files: frames extracted from the videos as .jpeg + .pmr: PhotoModeler project proprietary format- 3D point cloud provided as .dxf- animation showing the model as .gif The width calculated from the reference scale is also provided, along with the substransect lengths obtained from the smoothed Posidonia Ultra Short Baseline (USBL) underwater acoustic navigation.Due to difficulties with time synchronization there is a 15s delay between the time shown in the videos and the ship time (PC time). Both times are listed in the table.If any video frame from this collection is used, please credit the pictures to Tomas Lundälv, mailto:tomas.lundalv@loven.gu.se If any image of the 3D models is used, please credit the images to Laura Fillinger, mailto:Laura.Fillinger@gmail.com
