The purpose of the mission done in East Greenland with Vagabond, between August 8th and 18th, 2014, was to reach an exceptional site of the volcanic margin, at 200 kilometres north of Kulusuk, where basaltic flows of the margin are lying on the Precambrian platform. The study of the geometry of this contact is basic because it allows to understand the mechanisms at the origin of this type of transition continent-ocean. The mission, although short, was successful, thanks to Vagabond... and her crew!
