Description The broad theme of the observational seminar this quarter will be observations of tracer transport and lateral and vertical dispersion (mixing) from the surfzone, estuary, shelf, and ocean-scale. Through examination across scales we will see unifying methods and themes from the basin scale to the surfzone. Each week the first half of class will consist of student-led presentations of a key papers in the field, followed by a hopefully broad and energetic discussion by all present. Though students are encouraged to formally register for the class, collegial participation by interested post-docs and PIs is highly welcome.

Course Requirements Students should register as S/U. Students will be expected to present at least one paper during the quarter and participate in the discussion each week. To encourage thoughtfull discussion, registered students will be asked to submit a hand-written question or comment on the paper prior to the commencement of the discussion.
