Course Description

An introduction to marine geology and geophysics. Topics include the geologic time scale, structure of the Earth, plate tectonics, marine sedimentation and stratigraphy, depositional and erosional processes, submarine morphology, paleoceanography, sea level changes and the evolution of the Mesozoic-Cenozoic global ocean and climate. This course is intended as part of a two-semester core course for first year MIT-WHOI Joint Program graduate students in marine geology and geophysics. However, it has also been structured to be appropriate for non-G&G students as a single semester course. There will be two 1-1/2 hour-long lectures each week. Problem sets will be regularly assigned and there will be occasional labs, literature discussion sections and a short cruise scheduled during the semester.

Grading

Mid-term exam -- 40%
Final exam -- 40%
Labs/Problem sets -- 20%

Readings

Because of the breadth of topics covered there is no single textbook that is adequate for the purpose. Lecture notes will be distributed for each class along with reading assignments in several relevant textbooks placed on reserve or in journals. Students are responsible for the material covered in both the lectures and the reading.

Recommended Text Books

On reserve in Lindgren Library, Building 54, MIT, and in Clark 237, WHOI:
