Exploring Uncharted Territory off Oregon's Coast

This is part of a series of posts about our Pacific Hotspots expedition. Today's highlights: On their final day in Oregon, the crew ventures into uncharted territory and finds a variety of corals and fish.

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.

Exploring Oregon's Coquille Bank

Oregon Leg, Day 4

Today we ran the R/V Miss Linda twenty miles west of Bandon, Oregon to Coquille Bank. This offshore bank, also known as the Bandon High Spot, rises up off the continental shelf break to a relatively shallow 300 feet in depth. Oceana worked to protect this area from bottom trawling in 2005. The regulations went into place in 2006 and now five years after the area was protected, we had the chance to dive there with the ROV. 

In 2007, Drs. Mark Hixon and Brian Tissot published a scientific paper on the effects of bottom trawling at Coquille Bank. They found striking differences in the seafloor communities between heavily trawled and untrawled areas including more fish abundance and more diversity in the untrawled areas. They also found that bottom trawling affects marine life living in soft sediments and not just rocky seafloor habitats.

Coral Gardens Near Bandon, Oregon

 Oregon Leg, Day 3

Last night we anchored the R/V Miss Linda just north of Bandon, Oregon and two miles offshore. We woke to calm seas and high anticipation for another day of work with the Remotely Operated Vehicle (ROV), surveying seafloor habitats. 

Steaming west about six miles offshore we crossed paths with a rapidly moving pod of dolphins and we were graced with the company of black-footed albatross and sooty shearwaters.

As the ROV descended on the first dive, we passed through a swarm of krill just before reaching the seafloor 300 feet down. At the bottom we saw a garden of colorful corals, sponges and crinoids that looked like sword ferns in an old growth forest.

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.

Close Encounters With Humpback Whales and Orcas

California Leg, Day 3

Yesterday was a spectacular day as we saw some of the most colorful and rich habitats we’ve seen yet! The objective was to gather footage from some of the more spectacular areas of pinnacles and rocky reefs that we started to explore last year.

At the outer edge of the Monterey Peninsula, just off Pebble Beach, is a spectacular reef that we explored last year. While golfers marveled at the sites from the world famous course on shore, we marveled at the wildlife above and below the ocean offshore. 

We brought several guests with us including a representative from Mission Blue, another organization focusing on ocean exploration and conservation. The weather was sunny and warm, however a medium-sized southerly swell made the ride a bit bumpy and our cable operators got soaked.

The Carmel Pinnacles were protected as a marine reserve in 2008. This combination of rocky reef at the edge of a steep canyon wall that drops thousands of feet provides a rich feeding ground, as nutrient-rich water is pulled up from the deep through a process called upwelling. 

As we set our ROV equipment up for the first dive, we saw two large humpback whales swimming right by our boat. We explored a depth range of 90-150 feet. The habitat was composed of large pinnacles and boulders, jutting out of a sandy seabed. Nestled in the cracks and crevices were china rockfish, gopher rockfish, and treefish, while we encountered several schools of black rockfish hovering at the tops of the reefs.
