NOAA Ship Ron Brown - ROV Cruise
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).

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... |
