Additional Resources

  1. FFTWaveForm - The FFT program available here provides a useful teaching aid to understand the Fourier Transform of time series data a fundamental task in science and engineering.
  2. BODC's EDSERPLO - EDSERPLO is basically a data visualisation system (i.e. for all time series and profiles, including ADCP and wave spectra), but it does not have automatic QC tests built in, as these will either already have been carried out as BODC transfers data into its internal format or they are planned but not yet implemented. EDSERPLO does perform tidal analyses, predict tides, and calculate residuals, filter to hourly values, and perform some gap filling (but only for a couple points, as opposed to more aggressive filling in other systems), and flag data values. All of these operations are supported by appropriate plotting. It also generates statistics (monthly mean sea level, extremes, surges). EDSERPLO forms part of the BODC QC process, but is not a standard in itself.
