Plate tectonics is the unifying paradigm for Earth Sciences and links phenomena such as past climates, tectonism, volcanic events, and evolution of life. As discussed in our 2009 EOS Trans. AGU article, the Seminar on Advanced Plate Tectonics was offered by the Dept. of Geology & Geophysics in the Schoold of Ocean & Earth Science & Technology in Fall 2008. We examined modeling and analysis techniques used in the kinematic study of plate tectonics, which has seen many technical innovations over the last decade not yet in textbooks. We first reviewed seafloor morphology and its expressions in potential fields, the magnetic anomalies left by seafloor spreading and their interpretation, the status of seafloor and seamount chronology, and use of paleomagnetism. Unlike recent plate motions studied by GPS or VLBI, the analysis of past plate motions requires the use of finite rotations; we thus reviewed the basics (spherical trigonometry, matrix operations for rotations, quaternions, etc.) and proceeded to study techniques used to model relative (RPM) and absolute (APM) plate motions. A novel aspect of this course was eight remote guest lectures by leading experts from around the world. These talks were delivered via Skype or iChat and recorded, merged with the PowerPoint or KeyNote presentations, converted to video podcasts, and made available here in both 480p (iPod, iPhone) and 720p (Apple TV) resolutions.
