Woods Hole Oceanographic Institution
Microbiologist, chief scientist
As chief scientist, Dr. Sievert will coordinate the overall project and lead the science team during the cruise. He will also be involved in experiments on carbon fixation, genome analysis, and microbe incubations.
Dr. Seewald will study the chemistry of the vent environment and participate in experiments using the Isobaric Gas-tight Samplers (IGTs) he helped design.
Dr. Taylor will help in deploying the Large Volume Pump (LVP) to filter microbes for molecular analysis.
Dr. Thomas will study active microbes collected in hydrothermal fluids at the vents.
McNichol will look for microbes in fluids collected by the Isobaric Gas-tight Samplers (IGT) and will measure their activity in the lab.
Sylva will help Dr. Seewald collect fluid samples from the vents and will analyze the gas content contained in each sample.
McCulloch will help Dr. Seewald measure the chemistry of fluid samples.
Barone will cover the cruise for Scholastic
's Science World classroom magazine, and she'll also help out the science team on board the ship.
Carnegie Institution of Washington
Dr. Foustoukos will lead experiments to understand nitrate reduction in microbial communities using high-pressure devices he developed in his lab.
Dr. Pérez-Rodríguez will work with Dr. Foustoukos during experiments on nitrate reduction by microbes.
Rawls will help Dr. Foustoukos and Dr. Pérez-Rodríguez with high-pressure experiments on microbes collected at the vents.
Dr. Vetriani will supervise biofilm sampling, RNA analysis, and culturing of vent microbes.
Dr. Giovannelli will isolate bacterial species from biofilms that form at vent sites and preserve those samples for later study.
Grosche will work with Dr. Costa to culture microbes contained in biofilms.
Banyuls-sur-Mer Oceanological Observatory, France
Nadine Le Bris
Dr. Le Bris will deploy sensors on Jason
(and leave some sensors on the seafloor) to measure and map the chemistry of microbial habitats.
Peru will help Dr. Le Bris calibrate her sensors, which can measure sulfides, pH, oxygen, iron, and temperature.
E.-M.-Arndt-Universität, Greifswald, Germany
Ponnudarai will study the proteins made by vent microbes.
Scripps Institution of Oceanography
Dr. Felbeck will study symbionts that live inside tubeworms at the vents.
Helmholtz Centre for Environmental Research, Leipzig, Germany
Wei will participate in experiments incubating vent microbes.
Center for Marine Environmental Sciences, Bremen, Germany
Sollich will study lipids (fats and oils) made by vent microbes.
Shanghai Jiaotong University, Shanghai, China
Xiang will study the genomes and metabolism of vent microbes.
Georgia Institute of Technology
Dr. Germanovich will measure changes in the flow rate of vent fluids with an instrument he developed.
