The OET and the Nautilus

The Nautilus, the research vessel of the Ocean Exploration Trust (OET, chaired by the famous explorer Bob Ballard), was fitted out with sonar scanning equipment in order to undertake standard oceanographic missions.

This equipment included a Kongsberg EM302 multibeam echo sounder (30 kHz, 1 °x1°) and a Knudsen Chirp 3260 sub-bottom profiler (3.5 & 15 kHz). The team was asked to monitor the installation, undertake the sea trials, and assess the shipboard sonar systems.
