Course Outline

Overview of marine geology and of this course

• Seafloor provinces


• Ocean basins, continental drainage basins


• Hypsometric curve, depth-age and area-age relationships for ocean crust/lithosphere
  

• Major plates and plate boundaries


• Distribution of seismic and volcanic activity, heat flow


• Paleomagnetism and the age of the oceanic crust


• Driving mechanisms, paleogeographic reconstructions

• The context: ocean circulation, oceanic biogeochemical cycles, and particle transport


• Plate stratigraphy: sediment distribution in space and time


• Calcium carbonate sedimentation and the CCD: global, regional, and local


• Opaline silica sedimentation


• Other sediment types: detrital, authigenic, organic carbon


• Particle distributions and sediment reworking

Midterm Exam (in class)

How do we define sediment ages? What are the effects of organisms on the sediment record?

• Sediment dating and sediment accumulation rates


• Bioturbation

• Interstitial water in marine sediments


• Hydrothermal systems

• Structure of oceanic crust, types of evidence


• Formation and aging of oceanic crust, heat budgets

• Classification and distribution of continental margins


• Passive margins, active margins

• Goals and methods of paleoceanography, climate history of the last 3 m.y.


• Climate and ice volume history of the past 100 m.y.


• Paleogeographies and past ocean circulation

Course Requirements:

Problem sets (3)
Leading scheduled class discussions of journal articles
Participation in formal and informal class discussions
Mid-term exam (in class)
Take-home final exam
Proposal and oral presentation of proposal

Evaluations will be based on performance on these requirements, on overall participation in class and discussion section, and on comprehension of course material demonstrated in interactions with instructor. The expectations, some of the assignments, and the context for evaluation are different for undergraduate and graduate students in this class. Class lectures and information from discussion sections are critical to your understanding and performance in this class.
