Studying Fe-Oxidizing Microbes on Loihi Seamount -- JASON2 on the R/V Melville -- MGLN10MV

Did you know that the Earth rusts? And that that can be a good thing for bacteria which may actually grow by the same chemical reactions? The Iron-Oxidizing Microbial Observatory (FeMO) uses the Loihi Seamount as a natural laboratory for studies of Earth's rust-forming microbial inhabitants to address the basic questions of who they are, how fast do they grow and form rust, where and why do they do it, and what are their environmental impacts?

Day 08 -- 29 September 2008 -- Mariprofundus Ferroxydans
Clara Chan has grabbed some bacteria from the slurp containers and put the “slurpings” into microscope slides that have special chambers in them. The chambers are grooves into which the bacteria, some filtered seawater and some nutrients are added in the hopes that the bacteria will survive and grow under the microscope. Daily report ...
Day 07 -- 28 September 2008 -- Going On Without Elevator
The decision was made to leave the damaged deep-sea elevator on the bottom. The risk and cost in dive time was judged too great. The most valuable part of the elevator, the glass floats, were gone already. So we continue with dive J2-367 but without elevator. Daily report ...
Day 06 -- 27 September 2008 -- Implosion of Elevator Floatation
The elevator started its decent with 8 of these “hard hat” spheres bolted to the top. At some point, as the pressure increased, one of the spheres imploded, and the concussion caused the others to implode as well. It was loud enough that it was heard in a stateroom in the bottom of the ship. Daily report ...

JASON Dive J2-366 Image Gallery
Dive J2-366 is aimed at the FeMO Deep site and Ula Nui, at about 5,000 m water depth. As we learned during this dive, operating under such extreme water pressures is not always without problems. Even though the yellow glass spheres imploded on the elevator, making it too damaged to be used in our operations, the dive continued successfully for another 24 hours. 

Day 09 Image Gallery
Jess is recording dive info from the watch logs into an spreadsheet so that samples can be tracked electronically and are properly archived.

JASON Dive J2-365 Image Gallery
This is the first dive library for the FeMO3 expedition. More than 70 still camera images from the JASON have been brought together here with the event numbers from the JASON Virtual Van. Overall this gallery will give you a good overview of what all happened during this 58 hour long to the Loihi seafloor.

Day 08 Image Gallery
Clara is looking at Iron oxidizing bacteria through the microscope. The screen shows one form that the bacteria take. Even though things didn't go as planned with the elevator, the scientists are continuously pushing forward because there is much to do, to analyze and to study.

Day 07 Image Gallery
Dive J2-367 starts today with a detailed 300x300m mapping survey of the Ula Nui area in the plans. The weather was calm and splendid and thus a good opportunity for Brian Midson and Shawn Doan to observe the Jason launch with the small boat.

We are pitching and rolling to bring you the latest news from Loihi
Shawn Doan and Anthony Koppers are riding the waves of the Pacific for the second time to bring you the latest research surfacing during the third FeMO seagoing expedition to the active vents on Loihi volcano. Stay tuned for daily image and video galleries, interviews and reports from our adventures on board the R/V Thomas G. Thompson and the exciting research carried out on the youngest Hawaiian volcano forming just 960 meter below the sea surface and 19 miles to the southeast of the Big Island.
