Woods Hole Oceanographic Institution

Stefan Sievert Stefan Sievert
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.

Jeff SeewaldJeff Seewald
Dr. Seewald will study the chemistry of the vent environment and participate in experiments using the Isobaric Gas-tight Samplers (IGTs) he helped design.

Craig TaylorCraig Taylor
Dr. Taylor will help in deploying the Large Volume Pump (LVP) to filter microbes for molecular analysis.
François ThomasFrançois Thomas
Postdoctoral researcher
Dr. Thomas will study active microbes collected in hydrothermal fluids at the vents.
Jesse McNicholJesse McNichol
Graduate student
McNichol will look for microbes in fluids collected by the Isobaric Gas-tight Samplers (IGT) and will measure their activity in the lab.
Sean Sylva

Sean Sylva
Research associate
Sylva will help Dr. Seewald collect fluid samples from the vents and will analyze the gas content contained in each sample.

Kerry McCullochKerry McCulloch
McCulloch will help Dr. Seewald measure the chemistry of fluid samples.
Kerry McCullochJen Barone
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

Dionysis Foustoukos Dionysis Foustoukos
Dr. Foustoukos will lead experiments to understand nitrate reduction in microbial communities using high-pressure devices he developed in his lab.



Ileana Pérez-RodríguezIleana Pérez-Rodríguez
Postdoctoral researcher
Dr. Pérez-Rodríguez will work with Dr. Foustoukos during experiments on nitrate reduction by microbes.

Matt RawlsMatt Rawls
Rawls will help Dr. Foustoukos and Dr. Pérez-Rodríguez with high-pressure experiments on microbes collected at the vents.

Rutgers University

Costantino Vetriani

Costantino Vetriani
Dr. Vetriani will supervise biofilm sampling, RNA analysis, and culturing of vent microbes.



Donato GiovannelliDonato Giovannelli
Postdoctoral researcher
Dr. Giovannelli will isolate bacterial species from biofilms that form at vent sites and preserve those samples for later study.
Maria PachiadakiAshley Grosche
Graduate student
Grosche will work with Dr. Costa to culture microbes contained in biofilms.

Banyuls-sur-Mer Oceanological Observatory, France

Nadine Le BrisNadine Le Bris
Marine chemist
Dr. Le Bris will deploy sensors on Jason (and leave some sensors on the seafloor) to measure and map the chemistry of microbial habitats.


Erwan PeruErwan Peru
Assistant engineer
Peru will help Dr. Le Bris calibrate her sensors, which can measure sulfides, pH, oxygen, iron, and temperature.

Shanghai Jiaotong University, Shanghai, China

Xiao XiangXiao Xiang
Xiang will study the genomes and metabolism of vent microbes.

Georgia Institute of Technology

Leonid Germanovich
