Juan de Fuca Ridge Flank Hydrogeology*

Dates: 5 July 2010 - 5 September 2010

Co-Chiefs: Andrew Fisher, University of California, Santa Cruz

Takeshi Tsuji, Kyoto University

Staff Scientist: Katerina Petronotis, Integrated Ocean Drilling Program/Texas A&M University

Staff Educator: Leslie Peart, Deep Earth Academy/Consortium for Ocean Leadership


For more about this expedition, follow the team listed below, listen to one of our Ocean Gazing podcasts, read what scientist Amanda Turner has to say on her blog, or watch Beth Orcutt's all new video about CORKS and how they're put together.


This expedition is part of an experiment that builds on results from Leg 168 and Expedition 327 to the Juan de Fuca Ridge in 1996 and 2004. We've been working in this area for quite a long time! Our main goal is to measure how water moves in the ocean's crust and how the water changes the rock around it. We want to know more about the role of heat and pressure in the water's movements, where and how it is stored, and connections between its pathways.

We're also very interested in the microbes scientists have been finding there. Think about it -- microbes living where there's no light or oxygen. How are they adapted to living in the seafloor water and rock, and what changes do they cause in the rock around them?

But why spend 60 days at sea working 'round the clock to sample water in the seafloor? To have a better understanding of the role this groundwater plays in the the processes of the Earth and ocean.  During Expedition 327, our scientists, engineers, and drillers will lower sampling tools known as CORKs in two new holes we're drilling in the oceanic crust below. The tops of the holes will be sealed from the ocean water above, and each CORK will sample water and microbes while collecting temperature and pressure measturements for several years. Future expeditions with submersibles will recover the tools and allow us to conduct water flow experiments in a network of CORKs in the area.

The Expedition 327 team includes an international education and outreach program intended to develop tools and techniques that facilitate the communication of exciting scientific drilling results to a broad audience, build educational curricula, and create media products that will help achieve critical outreach goals.

L’expédition 327 fait partie d’une expérience à long terme regroupant plusieurs disciplines et poursuit les travaux entrepris lors de l’expédition 301.

L'objectif de ces missions est de collecter des données pour améliorer la compréhension des échanges d’eau entre l’océan et les roches du fond des océans. Les chercheurs veulent savoir comment l’eau circule à travers ces roches encore chaudes nées dans la dorsale. L’objectif est aussi d’établir des relations entre la circulation des liquides, la transformation des roches et l’activité des micro-organismes vivants mais aussi les rapports entre mesures sismiques – réalisées lors d’une mission précédente - et les propriétés aquifères de ces roches.
 
Durant l’expédition 327, deux nouvelles stations de mesures vont être placées dans deux nouveaux forages. Il y aura également une révision de la fixation d’une station installée par l’expédition 301 alors qu'une autre va être remplacée pour améliorer les études à long terme. 
 
Grâce à l’expédition 327, des expériences menées à l’aide de sous-marins vont être réalisées dans chaque forage. De plus, grâce au réseau de stations de mesures installées, les scientifiques auront accès à des données relatives à la circulation de l'eau à travers la croûte océanique.
 
Cette expédition va aussi inclure un projet international d’éducation et de promotion. Cette équipe aura pour mission de rendre plus accessible les données scientifiques de ce programme de forage, de construire des documents à usage éducatif et d'assurer les objectifs de communication.

Meet our fantastic Education and Outreach Team for Expedition 327!

Jackie Kane; St Ursula Academy (high school), Toledo, Ohio

Jackie Kane joins JOIDES Resolution Expedition 327 and its team of educators to continue the outreach of shipboard science to academics and the public worldwide. She holds two master degrees in education and approaches her 24th year of teaching in Ohio, grades 7-12. Jackie participates in workshops and research experiences, particularly in remote sensing and nanotechnology at the University of Toledo, vacuum science through the American Vacuum Society, and alternate energy through a BP grant (constructing a wind and solar powered-lamppost outside her classroom at school, 2007). She advises JETS and Science clubs at her school, each of which has recently won Engineering and NASA competitions.

Jackie’s experiences with webcasts, publishing, inventing, and presenting, combined with other life experiences, equip her for this capstone work aboard the JR. She enjoys presenting at conferences and workshops and developing solutions to problems. And though she marvels at the process for preparing articles for publications, Jackie has authored and co-authored articles in science education journals.

In what seems like a long time ago, Jackie believes her trip around the world on the Universe Campus ship, repelling off cliffs and careening down the Green River in Colorado Outward Bound, finessing her way through motherhood, while relying heavily on her faith and husband of 36 years, adds to the way she looks at science, education and communication. Jackie hopes to stir up the sediment of buried curiosity for ocean research in her home area on the western shore of Lake Erie. Come join her on Expedition 327, summer 2010, as she studies alongside the experts to explore the largest lab on Earth, the ocean floor and below!

Stephanie Keske; College of Architecture, Texas A&M University

I am a student in the Department of Visualization within the College of Architecture at Texas A&M University. I received my B.S. in Visualization in May, and I will be continuing at A&M in pursuit of a M.S. in Visualization starting in the fall. My interests include computer graphics, photography, videography, and traditional art.

Though I attend college in Texas, I am from the Midwest at heart. I grew up in Ohio and completed high school in Michigan. When I'm not spending time doing projects and staring at a computer screen, I love to be outdoors. In the summer, I enjoy backpacking, rock climbing, and kayaking, and in winter I ski and snowboard.

Bejonty Richardson; Virginia State University; Petersburg, VA; HBCU Fellow

I am currently a rising sophomore at Virginia State University, majoring in Manufacturing Engineering. My concentration is in green engineering and processes.  I was born in Atlanta, Georgia to an Air Force mom. Moved to Washington State when I was 2 and resided there until 5 years ago when I moved to Virginia.  I am a lifetime student. I enjoy being in class, learning new things and things that challenge me. I'm especially interested in all things hands-on, if I don't know what it is, I'm liable to take it apart, which led me to my first great love, Legos.  I have been a tutor since I was in the sixth grade and played the violin since the fifth. I have an ever increasing love for snakes and other animals which is apparent from the 30 walking sticks, 5 frogs, 3 lizards, 2 snakes, 4 cats, 25 fish and 3 dogs I have owned in my life thus far. I have aspirations to travel all over the world.  I can be found either reading or studying more often then not, although I would love to spend more of my time doing the things I love like camping, rock climbing, caving, white water rafting and other extreme sports 

Dinah Bowman; Illustrator/Adventure Artist, Portland, TX 

 I have been a professional artist for the past 30 years. My gallery and frame shop is located in Portland, Texas, a little town on the Gulf of Mexico. I work in a variety of media including watercolor, acrylic, collage, scratchboard, and GYOTAKU (Japanese fish printing). I enjoy doing illustrations of fish, birds, plants and other biota found in marine and estuarine environments. My fine art pieces can be found in public and private collections across the U.S. During my spare time, I enjoy traveling, nature watching,fishing, visiting art galleries and museums, SCUBA diving, "junqueing", and reading.

Brigitte Thiberge, High School Teacher, Normandy, France

My name is Brigitte. I'm a 41-year-old French teacher living in Normandy.

I graduated in 1992 and passed an agregation in Rennes. I was happy studying biology and geology for 5 years after the baccalaureat (end of high school ) but then it was the end of my studies and the beginning of another story, being a teacher in a quite difficult area where I could learn real teaching!  Three years later, I had a quieter place in a high school in Bayeux where I stayed. I love this job but I'm interested in plenty of other things - that is why I'm always exploring other experiences when I can, other types of lessons, other levels, other topics. It's why I'm so happy to jump into the JOIDES Resolution - I remember my own teachers speaking of it at university! It's why I'm also very glad to discover and work with all of you. See you soon! 

Jean Marie Gautier; High School Teacher, Normandy, France

Jean Marie is from France and is 36 years old. He graduated from a French Agregation of biology and geology. As a teacher in High school, he worked for 5 years in French Guyana. There, he managed several innovative educational programs. When he returns to Normandy in September, he hopes to carry on with exciting educational programming.

Getting involved in this a project is a youthful dream for Jean Marie!
