SIO 218A Observational techniques in physical oceanography Goals/methods: Learn currently used methods and instruments Understand principles of observation/technique Become critical of limitations, errors, suitable applications Ability to judge/choose method/instrument of choice Tradeoffs in capability, cost, deployment modes Practical advice (common errors, things often overlooked) Existing programs supporting types of observations, sources of data Hands-on demonstrations and homework examples Design of own sampling and instrument set-up, data collection, analysis Lab, field, ship visits
Notes/materials/powerpoints/software: Will be posted on anonymous ftp server geo.ucsd.edu, log in as “anonymous” with your address as password, and go to /pub/usend/teach/spring14/218A_techniques (use regular ftp, secure sftp does not work for anonymous log-ins), or point your browser to ftp://geo.ucsd.edu/pub/usend/teach/spring14/218A_techniques Contact: Uwe Send, NH
- level depends on participants, will try to find the right mix of information that is most useful to everybody. Please tell if boring or hard to follow etc. - will give letter grade - instead of written exams just a 20min oral at the end - no regular homeworks, but approx. 3 practical exercises, 1 short presentation, and occasional voluntary example problems - will be somewhat irregular schedule, some makeup dates probably, but also 1-2 trips to labs, manufacturers, facilities - find best days/times for everybody, and also makeup options
