Sediment echosounder (3.5 kHz) profiles of POLARSTERN cruise ANT-IV/2@en

The 3.5 kHz-sediment echosounder profiles of cruise ANT-IV/2 were originally recorded on 10 paper rolls. Each roll was digitized using a scanner \"Océ CS 4044 Colour System\" by SAGA GmbH (http://www.digitalarchivieren.de). Resulting 10 files are stored in tif-format with a resolution of 200 dpi and were zipped to reduce its size by about 30%.
