Description The broad theme of the observational seminar this quarter will coastal sub-mesoscale processes. That is, processes with length-scales of a few km or smaller from the shoreline to the shelf break. Here coastal means small islands as well as continental coasts. We can also include general sub-mesoscale processes or coastal processes by themselves. In particular, oceanic submesoscale processes will inform coastal ones. Of course, the coast has sloping bathymetry and a boundary which induces extra sources of spatial and temporal varibility. It is anticipated that these seminar will be germane to the NASCAR, FLEAT, and Innershelf DRI programs. Processes can include intrinsic shelf variability, internal waves, fronts, wakes, topographic driven flows, Langmuir circulation, surface gravity wave driven processes. 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.

Presenters and Papers will be posted here
