Hawkes Challenger
Graham Hawkes “Flies” Under Water in the Deep Flight Challenger – Hawkes Ocean Technology invented Deep Flight Challenger, a winged submersible with the power to revolutionize deep sea travel. ESS contributed a 45-lb/ft3 foam tested to full ocean depth as the buoyancy package for this remarkable vehicle.
HOV Alvin
Alvin is the most easily identified HOV in the world. Operated by the scientists at Woods Hole Oceanographic Institute since 1964, Alvin has made more than 4,600 dives. From 2010-2012, ESS worked closely with WHOI on a system upgrade, supplying over 300 cubic feet of syntactic foam extending Alvin’s working depth from 4500 meters to 6500 meters.
