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.

Among the beautiful creatures seen today were orange zoanthids (pictured), cup corals, large white sun anemones, and beds of hot pink strawberry anemones covering boulders and rocky outcrops

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
Newport, Oregon

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.

The Hidden World of the Pacific Seafloor

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.

Rough Seas Near Oregon’s Orford Reef

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.

Ranger Sets Sail to Explore Seamounts and Sea Canyons

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!

California Leg, Days 4-5

Friday concluded the Monterey portion of the expedition, and we had high hopes and much enthusiasm for the last day. We successfully completed three fantastic dives exploring three unique habitats.

This section of the expedition involves two ROVs, a compact one able to capture footage in more shallow depths and one designed to dive much deeper. The crew is still making improvements to the larger ROV so we used the smaller one to document bottom habitat consisting of sand, boulders, and large white sponges inside Point Pinos reef; the pinnacles at Asilomar State Marine Reserve; and investigated marine life hiding within the ledges of the Monterey Shale Beds.

The strong swells we had been working against all week calmed a bit under the overcast sky. Special guests joining us today included scientists from the Stanford Center for Ocean Solutions, a reporter and photographer from the Santa Cruz Sentinel newspaper, and documentary filmmakers from Sea Studios.

Our dive within the newly established Asilomar State Marine Reserve was truly extraordinary. We were pleasantly surprised to see that this marine protected area contained such large pinnacles, equivalent in splendor and color to what we observed further south near Carmel earlier in the week.

ROV Explores Seafloor Near Key West

Posted Tue, Sep 28, 2010 by Emily Fisher to diving, fish, grouper, key west, marine ecology, marine life, oceana gulf expedition, ROV

In the latest update from the Latitude, Oceana scientist Jon Warrenchuk describes the ROV’s dive near Key West.

The underwater ridge looked promising: South of Key West, 10 miles offshore and 200 meters deep. The bathymetric lines piled up steeply on the chart, indicating some steep relief in some otherwise flat habitat. As far as I knew, no one had ever seen what the seafloor looked like in that area. We deployed the ROV some distance from the site, trying to take into account the drift of the boat.
