Identifying "Skylites" for AUV Operations under Pack Ice:
The past decade has seen a remarkable evolution of sea-floor-based ice-draft profiling capabilities. Efforts have progressed from an original Beaufort Sea deployment of a single upward-looking acoustic echo sounder to the almost routine present-day positionings of special-purpose profiler units whic...
