On this Expedition:
As a primary scientific investigator for this expedition, my primary responsibilities include working carefully to establish the research goals and then to do everything possible while at see to fulfill these goals. Planning began several years ago and was based in part on a drilling expedition to the 90 East Ridge I also participated on. We have students at all levels on this expedition. The teacher's Sea90e web site was developed because we want young people to be directly involved with research at sea. Our goal is to "bring along" scientists of all ages. It is a lot of hard work, but we all like the work we do.
About myself:
Geochemistry; specifically determining the chemical composition of volcanic rocks and use of such data to define the mantle source of the magmas and the processes that affect the magmas during their ascent to the surface.
My degrees are a BS in Chemical Engineering and PhD in Chemistry. While doing graduate research in Chemistry we developed analytical procedures for determining the abundance of rare earth elements in terrestrial rocks. We found that the abundances of these elements differs in terrestrial rocks of different types; this result was a surprise given the chemical similarity of these elements. The obvious application was to use such data to understand geologic processes. As a result my career evolved toward geology and to specifically focus on using the chemical composition of igneous rocks to understand the sources and processes that form volcanoes.
For Students:
The ocean floor consists of sediment that overlies several kilometers of volcanic rocks that form by two processes: 1- volcanism associated with diverging plates at mid-ocean ridges and 2-volcanism associated with hot spots such as Hawaii in the Pacific Ocean and Kerguelen in the eastern Indian Ocean. In order to understand the sources and processes that form the volcanic part of the seafloor there are two ways of directly sampling the seafloor: drilling into the seafloor and recovery of drill core using a ship such as the JOIDES Resolution or dredging the seafloor where volcanic rocks are not covered by sediment.
Spending 1 to 2 months at sea with 20 to 30 scientists of varying age, nationality and different expertise is a intellectually, scientific and socially stimulating experience that is very different than our normal lives. Living and working on an oceanographic ship is a good example of people with different backgrounds working together towards a common goal.
