Digital terrain mapping of the underside of sea ice from a small AUV
International audience In April 2007 the first three-dimensional digital terrain mapping of the underside of sea ice to be done from an ice-launched autonomous underwater vehicle (AUV) was carried out at an ice camp in the Beaufort Sea using the Gavia vehicle, which could be launched and recovered t...
