Skip navigational side bar

Most of the data processing (see Data Processing page), tidal analysis (see Tidal Analysis page), and plots (see Time Series Plots page) completed for this report were created using Matlab® software, created by Mathworks (www.mathworks.com). Plots were converted to tagged PDF format using Adobe (www.adobe.com) Acrobat.

DISCLAIMER: The Matlab m-files provide partial documentation of the techniques used to create the plots in this report. The m-files are not turn-key programs and are not supported by their creator or by USGS.

This code was designed to run on Matlab 7.1.0 SP3 with NetCDF installed. Users are encouraged to look at http://woodshole.er.usgs.gov/staffpages/cdenham/public_html/
for more information about the NetCDF format.
