SIO 219: Observational Oceanography Seminar

Spring Quarter 2003

Detlef Stammer (email: dstammer     web:

The observational seminar meets on Friday from 12:00-1:00 during the academic quarters, in the reading room in Nierenberg Hall. The seminar is open to all. It is a forum for informal discussion of current literature on observational aspects of physical oceanography and for presentation of individual's work in progress. The subject matter for each quarter is determined by the participants, weighted towards the preferences of the enrolled students.

Reading each week is chosen to complement the topic. Normally the reading can be downloaded from UCSD's electronic reserves or directly from the journal. Readings that are not available electronically are placed in the NH reading room.

Enrolled students are requested to come prepared to ask questions based on the reading material.

The Spring 2003 discussions will focus on remote sensing applications in physical oceanography.

Presenting? Here are questions to address and a list of resources.
