NOAA Ship Ron Brown - ROV Cruise

View of Wecoma from Ron Brown.

After an 8 hour transit from the south Cleft site, the RON BROWN arrived at Axial Volcano early this morning and ROPOS began dive R622 at the Marker 33 site. Marker 33 and nearby Cloud vent are the most robust hydrothermal vent sites... More...

R/V Wecoma - CTD Cruise

After weeks of preparation we are on our way to Axial Volcano on the Juan de Fuca Ridge, 260 miles off the coast of Oregon. Our cruise on the RV Wecoma, operated by Oregon State University, is one of two cruises this year conducted by NOAA's Vents/NeMO Program. Another NOAA Vents' cruise on the R.H. Brown is also working at Axial Volcano, studying the seafloor with an underwater robot vehicle (ROPOS). More...

NOAA Ship Ron Brown - Jeff Goodrich

Yesterday we concluded at south Cleft with a dive to retrieve and deploy HOBOS (hot temperature recorders) at several vents in the Vent1 and Plume venting regions. Both these areas looked like mini-cities with vent skyscrapers scattered throughout. Temperatures at Vent1 in 1994 measured over than 340 C, more than triple the boiling point of water.. More...

R/V Wecoma - Missy Holzer

It's only the second day and it feels like business as usually already. When I started my "watch" (work period) at 0600 hours, the ship's crew and science staff was totally immersed in the work of the cruise, which is to gather ocean water samples in and around Axial Volcano crater. More...

Participant Perspective

Interview with Ana Metaxas
Biological Oceanographer

Jeff: What are you studying at Axial Volcano?

Anna: I'm interested in the period between when larvae are released into the water column and when they are recruited back to the benthic population. Also, I'm interested in why they settle in a particular location. The site may have other adults, the right chemistry or substrate texture. I want to put down larval traps to look at larval abundance in the water column and an array to see where they actually settle at different sites at Axial. We're not looking for a specific type of larvae. Last year we got a lot of limpets and some polychaete worms. We're probably going to get gastropods and we should get tube worms if it's in the right area. More...
