This week's guest: John Hocevar, Oceans Campaign Leader, Greenpeace USA

John Hocevar knew that he wanted to protect the world’s oceans from the first time he saw the beach when he was four years old. Since that time, the marine biologist has worked on a host of ocean conservation issues from protecting the habitat of endangered sea turtles in Florida to teaching marine biology and environmental science to students. John has extensive experience in coral reef conservation, and worked with Coral Cay Conservation to develop a coastal management plan for the Government of Belize. In addition to ocean conversation work, John has spent time organizing students around various environmental and social justice issues. Before coming to Greenpeace in 2004, John was the founder and executive director of Students for a Free Tibet.

Deepwater corals, like this sea whip (Halipteris willemoesi) photographed on Sunday by Timo Marshall, thrive in the deep waters of Pribilof Canyon

Thanks to great weather, state-of-the-art equipment and a top-notch crew, it has been a productive weekend for the team aboard Esperanza which arrived on site at Pribilof Canyon Saturday morning (July 28) when David Guggenheim and Michelle Ridgway made the first tandem dive in two DeepWorker submarines into Pribilof canyon to a depth of just over 1,000 feet and began to document a fascinating diversity of life, including a variety of corals, anenomes, sponges and fish. On Sunday, the ship visited a second site in Pribilof Canyon where John Hocevar and Timo Marshall completed a successful tandem dive, documenting more corals and successfully collecting a number of specimens with DeepWorker’s manipulator arm for analysis by scientists around the world.

Already, the Greenpeace-led team has accumulated nearly 16 hours of bottom time (8 hours per sub), more than all of the previous research done in this region combined. The subs’ high-definition video cameras have already collected over 120 Gb of data. The subs are performing linear transects which will then be analyzed on the video. Twin lasers spaced 20 cm apart allow accurate analysis of the size of organisms encountered.

The Esperanza is carrying two manned submersibles, a remotely-operated vehicle (ROV) and an international research team to the Bering Sea for a three week survey of Zhemchug and Pribilof Canyons,to map and document deepwater corals living at depths of more than 1,000 feet. The expedition was conceived of and is being led by Greenpeace.
