Most of the data processing (see Data Processing section), tidal analysis (see Tide Analysis section), and plots (see Time-Series Plots section) 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 U.S. Geological Survey.
This code was designed
to run on Matlab 7.1.0 SP3 with netcdf installed.
adcp_curr_ts: and
adcp_magdir_ts: Create single site plots of the time series of ADCP water flow data.
quickview_processed_waves: Creates single site plots of the time series of ADCP wave measurement data.
adv_ts: Creates single site plots of the time series of ADV water flow data.
obs_ts: Creates single site plots of the time series of OBS data.
ct_ts: Creates single site and multi-site plots of the time series of seawater properties from CT data.
met_ts: Creates plots of the time series of meteorological data from NDBC moored buoys, NOS water-level stations, and the COAMPS wind model.
pcadp_ts: Creates single-site plots of the time series of PCADP water-flow data.
pressure_ts: Creates single-site and multi-site plots of the time series of pressure measurements.
river_ts: Creates plots of the time series of river discharge data from U.S. Geological Survey streamgage stations along the Cape Fear and Pee Dee Rivers.
wind_ts: Creates plots of the time series of wind data from NOAA buoy stations, NOS water level stations, and the NCEP NAM wind model.
ttide_adcp_indiv: Performs tidal analysis on individual records of ADCP 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).
