Course Description: An introduction to marine geology and geophysics for non-majors.
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 for non-G&G students as a single semester
course. There will be two 1 1/2 hour lectures each week. Problem sets will be regularly
assigned and there will be weekly discussion sections and occasional labs during the
semester.
Text/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.
Grading:
Mid-term exam - 25%
Final exam - 25%
Labs/Problem Sets - 50%
