oceanwaves provides a set of functions to calculate
summary statistics for ocean waves, using a record of sea surface
elevation as input. For sea surface elevations derived from
bottom-mounted pressure transducers, the package also contains a
function prCorr() to correct for depth attenuation of the
pressure signal, and the swDepth() function from the
package oce can be used to convert pressure data into ocean
surface elevations (see the included package vignette).
waveStatsSP() produces wave height and period statistics
using spectral analysis methods, while waveStatsZC()
calculates additional wave height and period statistics based on a
zero-crossing algorithm.
See the package vignette for example workflows to proceed from raw pressure data to summary wave statistics.
Pressure corrections and wave statistics functions were adapted from
Urs Neumeier’s waves functions for MATLAB, developed from
earlier work by Travis Mason and Magali Lecouturier. http://neumeier.perso.ch/matlab/waves.html
