Description The theme of the theory seminar this quarter is ocean surface processes and inference of subsurface flow. Recent work on surface quasigeostrophy will be one focus, but other topics related to sea-surface processes (gravity waves, near-inertial oscillations) will also be discussed. There'll be a mixture of research seminars and student-led presentations of key papers. Students are encouraged to register for the class, and participation by interested post-docs and faculty is very welcome.
Course Requirements Students should register as S/U. Registered students will be expected to present at least one paper during the quarter and participate in the discussion each week.
The reading list below is under development. Participants are encouraged to suggest papers that they like to read and discuss.
