英文简介	The latest expedition to the DISCOL experimental area (DEA, www.discol.de) was conducted in 2015 during cruise SO242 with the German RV SONNE. The entire disturbance area was extensively mapped with the ship-mounted Multibeam Echosound (MBES) System. An AUV has been deployed several times in different modes for the acquisition of high resolution MBES, Side Scan Sonar (SSS) and optical data. Even with state-of-the-art positioning technology the remaining navigation uncertainties in the deep sea and the use of a variety of acoustical and optical sensors at different resolutions require detailed post-processing in terms of absolute geographic positioning to improve the overall accuracy of the data. The ship-based bathymetric map of the survey area was used as absolute geographic reference and the AUV-acquired high resolution-data sets available here were geo-referenced and aligned to each other (see the respective assigned PANGEA-links for the different data sets and Gausepohl et al., in review, for details) resulting in the most accurate geo-referenced dataset of the DEA to date.
