Operations to 11,000m: Nereus ceramic housing design and analysis

HROV Nereus, a full-ocean-depth hybrid remotely operated vehicle (HROV) built at the Woods Hole Oceanographic Institution (WHOI), dove nearly 7 miles to the bottom of the Marianas Trench in June 2009. Nereus was the third submersible to reach the bottom of the trench, but the first autonomous vehicle. Its hybrid design allows transformation from remotely operated vehicle (ROV) to autonomous underwater vehicle (AUV) simply by removing a work platform and releasing its tether.
