Thesis research on an experimental or theoretical project in Marine Science or Technology under a faculty advisor.
Ocean atmosphere dynamic interaction processes related to short-term and long-term climate variability. 2-layer models and physics of El Nino/southern oscillation, North Atlantic Oscillation and monsoon dynamics are discussed with the perspective of global climate change. During the semester the class will conduct a real-time monitoring experiment of the Pacific/Atlantic Ocean using the Internet. Also presented are advanced assimilation techniques of satellite (GEOSTAT, Topex/Poseidon, SeaWifs, MODAS) and in-situ data from the World Ocean Circulation Experiment (WOCE) in numerical climate models.
Investigations of a fundamental and/or applied nature representing an original contribution to the scholarly research literature of the field. PhD dissertations are often published in refereed journals or presented at major conferences. A written dissertation must be completed in accordance with the rules of the Graduate School and the School for Marine Science and Technology. Admission to the course is based on successful completion of the PhD comprehensive examination and submission of a formal proposal endorsed by the student's graduate committee and submitted to the SMAST Graduate Program Director.
