This is part of a series of posts about our Pacific Hotspots expedition. Today's highlights: rockfish, basket stars and hydroids.
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.
The U.S. government is nearing the conclusion of international negotiations for the management of fisheries on the high seas of the North Pacific Ocean. These quiet talks have been ongoing since April 2006 and are likely to conclude this week, which has huge implications for the oceans and Oceana’s work in the region.
Oceana has been participating in these meetings as a member of the U.S. delegation since 2007. Oceana’s Pacific Project Manager, Ben Enticknap, is at this week’s meeting in Vancouver, Canada, working to expand Oceana’s approach to freeze the footprint of bottom trawling and protect important ecological areas to international waters.
The negotiations are between the U.S., Canada, Japan, Russia, China, Korea and Taiwan (Chinese Taipei) and are seeking to establish a new fishery management organization to sustainably manage fisheries on the high seas of the North Pacific Ocean, as well as to establish interim measures to protect “vulnerable marine ecosystems” like seamounts, deep-sea corals, sponges and hydrothermal vents from destructive fishing practices.
Yesterday you heard about the Latitude’s foray into the Alabama Alps. Today, photos!
Here are some of the cool creatures our deep-sea ROV captured on camera. Which one's your favorite?
Special thanks to Nautica, whose support made our use of the deep sea ROV possible!
Wonder how the Spanish dancer, or Hexabranchus sanguineus, got its common name? When it swims, the frilled edges of its mantle resemble the color and movement of the skirts of a flamenco dancer.
When they're not swimming, Spanish dancers crawl along relatively flat surfaces with the edges of their mantle tucked up close to their bodies (see the picture). They feed on sponges and can produce a toxic chemical to protect themselves from predation.
