It’s not often that rare, deep-sea creatures present themselves to scientists in plain sight. But in a video captured last month during Nautilus Live, a five-month expedition that’s mapping and documenting seafloor ecosystems around the Gulf of Mexico and Caribbean Sea, an elusive dumbo octopus in the Gulf delighted scientists when it swam right in front of their remotely operated vehicle (ROV).
Earlier this week, Oceana launched an expedition to document three seamounts located between the islands of Mallorca, Ibiza, and Formentera, all of which belong to the Balearic Islands. Using an underwater robot known as a remotely operated vehicle (ROV), a team of Oceana marine scientists will capture footage at depths of up to 3,280 feet. The 10-day expedition will allow Oceana to learn about and map areas of ecological importance that are in need of conservation.
Great news from our Pacific expedition team! On September 3 the local Portland station KGW featured the expedition on the evening news.
This August, Oceana set sail to document deep sea corals and sponges off the rugged Oregon Coast using a Remotely Operated Vehicle (ROV) outfitted with high-definition underwater cameras. The areas they explored are places that we proposed be protected from bottom trawling, which destroys important habitat on the sea floor.

Today was the final day of our Pacific research expedition off the Oregon coast. We left Newport before daybreak bound for Stonewall Bank, more than 15 miles west. The seas calmed overnight and we had perfect conditions for conducting our research dives.

Siletz Reef/ Cascade Head
Today we departed Newport at 5 a.m. bound for the Siletz Reef off Lincoln City, Oregon. Large ocean swells rocked us in our bunks as Captain Bob Pedro steered the Miss Linda to our first dive site. We’ve been planning this expedition for many months and the excitement and anticipation was all leading to this. None of us were sure exactly what our ROV would reveal below the surface of the ocean, and we were eager to find out.

Pacific Important Ecological Area Expedition
Kicking off our 2013 Pacific Expedition, our Oceana crew arrived yesterday in Portland, Oregon, from Chile, California, and Alaska and united with our Oregon expedition leader, Ben Enticknap. Today in Newport, the Port was bustling with activity.

South Nehalem Reef
We awoke this morning to calm seas and a beautiful sunrise coming up over Oregon’s Cape Lookout. Knowing it would be the last land we’d see for the next six days, we motored offshore for three hours and arrived at South Nehalem Reef; over 20 miles off the coast. Getting the remotely operated vehicle (ROV) set up, our deployment and retrieval operations had already become second nature. Attracted by the only vessel in sight, hundreds of seabirds flocked our boat. They are likely accustomed to getting a fisherman’s scraps or bycatch tossed overboard. We were joined by albatross, sooty shearwaters, storm petrels, several species of gulls, and our favorites: tufted puffins. But the only thing we were sending over the side of the Miss Linda was our ROV.
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.
This is part of a series of posts about our Pacific Hotspots expedition. Today's highlights: more amazing basket stars, anemones and sea cucumbers.
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.
It’s a busy and exciting time of year for our campaigners on the water -- and for those of us who get to see the photos and videos of the incredible marine life and habitats that they send back to land.
As you know if you’ve been following the blog for the past week or so, we have a team off the coast of Oregon right now exploring important ecological areas. And today, our team in Europe is launching its seventh annual summer expedition.
This year the Oceana catamaran, Ranger, will sail for two months through the western Mediterranean and the Atlantic to study seamounts and sea canyons, ocean environments that are rich in biodiversity but relatively unexplored due to their depth and complex terrains. That’s where our scientists, divers and underwater robot (ROV) come in.
In one of the most exciting aspects of this year’s expedition, Oceana will collaborate with Portuguese government officials and scientists to investigate the Gorringe Bank, a little-explored seamount and an oasis of biodiversity southwest of Portugal. Oceana last surveyed these waters in 2005, but this time around, using the ROV, the team will be exploring and documenting areas more than 2,500 feet -- that’s about half a mile! -- below the surface of the ocean.
The ROV will record high-resolution videos and photos, which will ultimately be used to propose the creation of marine protected areas and other conservation measures.
We can’t wait to see what our teams find in the ocean’s depths. We’ll keep you updated as the journey progresses!
