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.

Oregon Leg, Day 1
Last night our six Oceana crew slept aboard the R/V Miss Linda, tied to the dock at the Charleston Marina. The captain and his two crew members arrived at dawn, started up the engines and walked our tired souls through an important safety briefing. The Miss Linda is a 76-foot research charter vessel that formerly worked these Pacific Ocean waters as a commercial fishing boat. The captain is experienced, confident and will certainly lead us safely through our five-day expedition.
Our objective today was to get situated working aboard the Miss Linda with our Remotely Operated Vehicle (ROV) while exploring a large area of rocky reef just south of Cape Arago. Over the next four days we will use the ROV to capture high definition video footage of some of the most remote and rugged areas off the southern Oregon coast.
By our third dive this afternoon, five miles offshore and over 150 feet down, the Miss Linda crew and Oceana crew were in sync. With each drop of the ROV we saw schools of rockfish hovering over a rich tapestry of seafloor life.

California Leg, Day 2
This morning after we passed the barking sea lions on the breakwater at the end of the harbor, we traversed through fog so thick there were no signs of land anywhere to be seen. We pushed trough swells upwards of 6 feet to get to our fist dive site of the day. A mola mola (aka ocean sunfish) we passed along the way didn’t seem to mind the intense swells as it basked on the ocean surface.
After motoring out 20 miles across Monterey Bay (north of the Monterey Canyon), we deployed the ROV at the former California halibut trawl grounds. As a direct result of the work of Oceana, this area has been closed to bottom trawling since 2006.
The seafloor here is primarily soft sediment and ranges in depth from 50-250 feet. The areas were teeming with signs of life, including burrows, tracks, and holes. Some places had a lot of juvenile fish and crabs suggesting these areas may be a nursery ground for fishery species. Overall, we were surprised by the diversity of habitat formations and creatures.
