Dr. Iturrino will provide a summary of the history of ocean exploration that has led to our current knowledge of the structure and composition of the oceanic crust. He will review early and recent geophysical techniques that have been used to understand the upper 6 km of the oceanic basement. He will also present some examples of sampling techniques that have been used for characterizing the nature of the volcanic basement and the importance of knowing its composition and structure.

In his previous talks, Dr. Iturrino has shared what we have leaned about hydrothermal vents and presented a history of ocean drilling. For additional educational resources from the Borehole Research Group, click here.

Exploration of the ocean floors recently began a new chapter with the start of the Integrated Ocean Drilling Project (IODP): http://www.iodp.org/

Lamont-Doherty continues to be one of the main partners in these efforts. Most of this effort centers on the Borehole Research Group (BRG): http://www.ldeo.columbia.edu/BRG/

Here is the link to the press release describing IODP: http://www.ldeo.columbia.edu/BRG/RESEARCH_PROJECTS/IODP/overview.html

Examples of activities that can be accomplished with BRG data have been created by Gerardo Iturrino and Stuart Robinson for a program at Texas A & M: http://www.ldeo.columbia.edu/BRG/EDUCATION/PROJECTS/index.html
