The
morning began with a warm-up puzzle construction helping us review the
importance of teamwork and strategy planning. Kristen led our morning
lecture about Arctic Coring. We discussed the importance of drilling in
particular locations, as well as a discussion on the nature of science
in the rationale behind drilling. Moving to the lab for a discovery
activity, we made some basic observations on the drill cores.
After lunch, we continued our work in the lab with our
discovery activity and made interpretations based on our observations.
John helped us in linking observations, regional geology, and glacial
land data to an interpretation of the ocean cores we observed, which
ties glacial geology to marine geology.
Later in the afternoon, Joerge and Jay lectured us on
ophiolites, and we did a hands-on activity which showed that seismic
velocities change when rocks are altered or metamorphosed. Returning to
the lab we observed drill cores of ophiolite rocks, where we could put
our finger on the contact between sheeted dikes and gabbro. (Which was
REALLY exciting!!)
