“Exploring the Earth with Ocean Drilling, part 2: Downhole Logging” with Gilles Guerin (Oct 2007)

by admin | Jul 28, 2023 | Scientific Ocean Drilling

Originally presented 13 Oct 2007

The Earth2Class Workshops this Fall feature two special themes: the “IODP (Integrated Ocean Drilling Program) ‘School of Rock’ Workshops” and the “Lamont Contributions to the IPY (International Polar Year).”

In July, seventeen teachers–including E2C founder Mike Passow–and twelve IODP researchers and staff members participated in the “School of Rock 2007: Exploring Ocean Cores at the Gulf Coast Repository.” (If you want, you can read the official press release.)

In our September E2C workshop, LDEO Borehole Research Group scientist Jill Weinberger, E2C Organizer Dr. Michael J. Passow, and others shared research about gas hydrates, along with selected educational activities and materials developed by the first and second SOR participants.

In this second SOR/BRG Workshop, Gilles Guerin will explain how strings of instruments lowered down the borehole reveal much more about the properties and histories of sea floor sediments and rocks. Gilles earned his PhD here at Columbia through his research into geophysical signatures of marine sediment processes. He has been the Logging Scientist on eight JOIDES Resolutionvoyages, as well as on other expeditions.

We will also have an opportunity to pilot test an educational activity about downhole logging that Gilles and Mike created for the SOR, as well as more opportunities to work through some of the classroom activities developed by JOI Learning and the School of Rockers.

Introduction to this Workshop

Since this Workshop and the September Workshop both relate to Ocean Drilling, gas hydrates, and “downhole logging,” you may wish to view the previous workshop’s introductory presentation.

Cutting-Edge Research

Dr. Gilles Guerin loves to use geophysical instruments to discover what lies beneath the surface of our Planet. Now an Associate Research Scientist in LDEO’s Borehole Research Group, Gilles earned degrees in Ocean Science and Offshore Engineering in Marseilles, France, before coming the Columbia to obtain his Ph.D. As part of his PhD, he explored the geophysical signature of various processes in marine sediments. Much of his research research has focused on understanding gas hydrates, so his talk makes a nice follow-up to Jill Weinberg’s September 2007 E2C presentation.

Although he has served in shore-based positions interpreting data logs from drilling, what really excites him is going to sea to obtain data. In 2006, he participated in the NGHP Expedition 1 off India. He experienced eight D/V JOIDES Resolution cruises between 1993 and 2005, and eagerly looks forward to future participation when the JR resumes its exploration as part of the Integrated Ocean Drilling Program (IODP.)
