For 15 years, I have been teaching Biology and Geology in secondary schools. I lived in Paris some years ago, now I am installed in the suburbs, 20 miles from the capital. At university, I began studying Biology in order to become a biology teacher. At this time, I discovered Geology and I fell in love with rocks! After graduation, I started teaching in a high school but at the same time, I completed a Master in Geosciences in 2003 then a PhD from University Pierre et Marie Curie in 2007. During these 4 years, I studied the uplift of the Oman passive margin along the Gulf of Aden, using telesismic tomography and sedimentology. It was a wonderful experience for me. I met a lot of enthusiast researchers: most of them are very good friends now. Also, I understood how scientific research in Geology makes progress which is, according to me, an important point to teach to the students. This is the reason why I think it's a great and unique opportunity for me to follow the expedition 362 aboard the Joides!

We have 4 micropaleontologists on board during Expedition 362 who are working together to track the age of the core.
Meet our micropaleontology team! From left to right: Freya for Diatoms, Wen-Huang for Foraminifers, Jan for Nannofossils and Sarah for Radiolarians.
Why are we using microfossils?

When we see all this mud coming from beneath the seafloor, we can ask ourselves the question: "What is it made of"?

When you hear "CORE ON DECK- CORE ON DECK" (it's always twice, not once, not three times, just twice), you have to go to the catwalk. It is a narrow, covered work area, wide enough for a lot of obese Maine coon cats however. I don't really understand that name. Maybe because I am French?

Yesterday, we starded our next hole in a new way because this time, we want to drill until the sediment/basement interface (1450 mbsl)! Before that, we have to build a reentry system that includes 754 m of "casing".
What is casing?

Deep hole often requires several changes of drill bits. When you drill the bottom of the seafloor, we can use the Advanced Piston Corer (APC) which is used to recover relatively undisturbed sediments from very soft to firm sediments.
The APC is a hydraulically actuated piston corer and it allows to recover continuous 9.5 m samples.
How does it work?

There is an important question to answer for the sedimentologists: where do the sediments come from?
One way to answer to this question is to take a look at the sands in the cores. It is one of the jobs of Kitty Milliken on the JR.
