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® 2012b v8.0.0. Users are encouraged to look at http://woodshole.er.usgs.gov/staffpages/cdenham/public_html/
for more information about the NetCDF format.

M-files for time series plots (see Time-Series Plots page)

adcp_curr_ts: Creates plots of the timeseries of vectorized water flow data.

adcp_magdir_ts: Creates plots of the timeseries of water flow data magnitude and direction.

waves_ts: Creates plots of the timeseries of wave measurement data.

wind_ts: Creates plots of the timeseries of wind data from NDBC moored buoys and FRF.

ndbc_tpw_ts: Creates plots of the timeseries of temperature, pressure and wave height from NDBC moored buoys.

pressure_ts: Creates multi-site plots of pressure measurements.

temp_ts: Creates multi-site plots of temperature measurements.

river_ts: Creates plots of the timeseries of river discharge data from USGS gauging stations.

M-files for tidal analysis (see Tidal Analysis page)

ttide_adcp_indiv and ttide_adcp_merge : Perform tidal analysis on individual records of ADCP and Aquadopp data.

t_tide: Performs harmonic analysis of a time series (called by ttide_adcp_indiv.m, ttide_adcp_comb.m, ttide_aqdp_indiv.m, ttide_aqdp_comb.m, ttide_argn_indiv.m, and ttide_argn_comb.m; Pawlowicz and others, 2002).
