During research cruise M87/2 COSY, Parasound echosounder data were collected onboard research vessel FS Meteor in May 2012. The profiles cover the northern sidewall of the Storegga Slide and the Nyegga pockmark field at the mid-Norwegian Margin. The uploaded dataset is converted to the SEGY data format, coordinates are stored in the bytes 73 and 77 in UTM-cm and the shot points are stored in byte 5. The coordinate system is UTM31 WGS84. For more information, see the cruise report (doi:10.2312/cr_m87_2).
