ICEWAVEGUIDE

Sonar methods rely on the use of an acoustic source moved underwater to probe the environment with acoustic waves. In this matter, military submarines have provided most of current knowledge on the general ice draft distribution (Percival et al., 2008, Rothrock et al., 2008). They allow accurate and rapid data to be recorded, but the currently available dataset relies on the declassification of military data, with very few trends. To solve this problem, Autonomous Underwater Vehicles (AUV) were designed. Since the first one launched in 1972, this technology has matured and can provide some of the best quality data currently available (Wadhams et al., 2006, P. Norgren and R. Skjetne, 2014). AUV still have to solve technological challenges related to communication and navigation, and associated costs. The dataset is therefore very sparse.
