SIO 221C Data Analysis Laboratory

Fall 2012

Professor: Sarah Gille

SIO Office: Nierenberg Hall 348
Telephone: 822-4425
e-mail: sgille at ucsd.edu

Meetings: Tuesday and Thursday: 12:30-1:50, OAR Conference Room

Course Requirements: Complete 3 projects from list below (or new ones to be added; the final project may be arranged with instructor to be tailored to research). Each project is scheduled to take 3 weeks. Students report on their progress at each class meeting and discuss problems and possible solutions with the group. Written reports are submitted at the end of each project. The course is taken S/U.

Data

Tools

NetCDF for Matlab. (And some tips for using netcdf.)
grabcdf.m
Thermodynamic Equation of Seawater - 2010 sea water toolbox, McDougall and Barker (2011). (If you look at older work, you might see reference to the CSIRO Seawater Toolkit.)
cptcmap.m: Function to create Matlab color tables using palettes created for the Generic Mapping Tools (GMT).
stick.m
arrow.m
m_map mapping package for use in Matlab, developed by Rich Pawlowicz (UBC).
Mathworks file exchange for user contributed Matlab scripts (suggested by Gabriela Chavez)
NetCDF Operators (NCO)
Comments on using LaTeX to write manuscripts (plus a short guide on equations from the American Mathematical Society web site).
A short guide to LaTeX
angsep.m computes distance between two geographic points in degrees
significance.m simple routine for computing statistical significance levels for correlation coefficients. For example, for 8 degrees of freedom, the 95% significance level would be "significance(8,.95)", which is 0.693.
