In this gorgeous new Oceana video Alexandra Cousteau delves into Monterey Bay to illuminate the diversity of life at the bottom of the ocean, a crucial habitat that is under the constant threat of obliteration from bottom trawling. Using an ROV the camera captures an otherworldly scene, as scallops flutter by and curlicued basket stars unfurl. Armies of shrimp and brittle stars scamper by, fed by the organic matter from above that drifts down the water column like snowfall, sustaining a remarkably rich community. In shallower waters, coral gardens that take hundreds of years to blossom shelter rockfish and ingeniously disguised crabs, and serve as a nursery for dozens of species of fish. Here octopuses go camouflage against the rocky shale, out of sight of the hungry sperm whales and sea lions from above. Anemone-covered spires upwell nutrient rich waters that feed shoals of krill, which in turn feed blue whales. It is an intricately connected ecosystem and it can be destroyed in an instant by bottom trawling. That’s why Oceana has pushed for an end to bottom trawling in ecologically sensitive areas. And that work has paid off in concrete victories: in 2006 NOAA protected 140,000 square miles of Pacific seafloor from the destructive practice, but more needs to be done. For the most part this world goes unseen by human eyes and it’s why Oceana is working laboriously to document these precious areas before they disappear.

Oregon Leg, Day 5
Friday was our last day aboard the R/V Miss Linda and it could not have been a better day for working on the ocean. We left the Charleston Marina at 7 AM bound for the nearshore reef south of Cape Arago and west of Seven Devils State Park.
As we were working in and out of Charleston today, we invited guests to join our expedition including Dr. Craig Young, the director of the University of Oregon’s Oregon Institute of Marine Biology and Dr. Jan Hodder from the Oregon Institute of Marine Biology.
The University of Oregon has been operating marine studies in the Charleston area since 1924 with year-round research programs beginning in 1966. Dr. Young and his graduate students have made hundreds of deep dives in submersibles and sailed on oceanographic ships in the Atlantic, Pacific and Indian Oceans. Yet surprisingly, nobody has ever been to the areas we went Friday with a Remotely Operated Vehicle (ROV) and underwater camera.

Oregon Leg, Day 2
We pulled anchor early this morning and ran the R/V Miss Linda to the Orford Reef, just southwest of Cape Blanco.
Cape Blanco is the westernmost point in the continental U.S. and is the dividing line of two distinct biological regions for the near shore ocean ecosystem off the Oregon coast. South of Cape Blanco is also infamous among mariners for its high winds. Today, with 20 to 25 knot winds and seas building up to 12 feet, our work was more like the “Deadliest Catch” than a reef survey.
