His projects have ranged from analyzing the benefits of the U.S. Clean Water Act and examining the impacts of fisheries management to studying visibility improvements in the Grand Canyon and preventing residential water shortages in California cities. After the Exxon Valdez oil spill, he served as a principal investigator on economic damage assessments for the State of Alaska and more recently for the National Oceanic and Atmospheric Administration on the BP oil spill in the Gulf

The Grand Canyon is designed to perform a broad range of subsea operations, with DP3-class station keeping for work in severe weather conditions.  Grand Canyon features a 250 t heave compensated crane, facilities to launch up to five ROVs simultaneously, and a below-deck carousel lay system for installation of power cables, umbilicals or tubular products.

The deep-seafloor we will be exploring during our expedition is an extreme environment of intense-pressure and eternal darkness hiding a rugged landscape akin to a combination of the grand-canyon and monument valley 3.5 kilometers beneath the waves.”   “Whilst at sea we will be using new technology to navigate underwater instruments between extinct volcanoes, twenty meter high cliffs and towering chimney structures built by long-dead hydrothermal vents.

Survey Ship Discovers Red Sea 'Grand Canyon'

Naval survey ship 'HMS Enterprise' nets stunning images of a Grand Canyon-style ocean floor hidden deep under the Red Sea. Discovering the 250 metre deep canyon after leaving the Egyptian port of Safaga the ship used her sophisticated EM1002 Multibeam echo sounder to create the 3D images, allowing the ocean floor to be seen for the first time. Commanding Officer of HMS Enterprise, Commander Derek Rae, said: “These features could be the result of ancient rivers scouring through the rock strata before the Red Sea flooded millennia ago. Some may be far younger – and still in the process
