OCEANLYZ: Ocean Wave Analyzing Toolbox
|
OCEANLYZ is a MATLAB/GNU Octave toolbox for analyzing measured coastal and ocean wave data. A Series of Matlab functions are presented in this toolbox which are developed in order to analyze wave data measured either in the field (i.e. ocean, sea, lake, or coastal area) or in a laboratory. This toolbox is capable of analyzing data measured by a wave gauge, wave logger, wave staff, ADV or any other instrument used for data collections. Although this toolbox developed for ocean/sea waves, it might be used to analyze other types of wave data. |

List of selected applications for this toolbox:
- Calculates wave properties from field/lab measured data.
- Uses spectral analysis and zero-crossing method for wave analyzing.
- Partitions wave spectra and separates wind-sea and swell data.
- Corrects pressure data that read by a pressure sensor to account for pressure attenuation in depth.
- Applies diagnostic Tail.

Sample File
|
This is a sample file contains one burst of real data measurement. Properties of the measurement are:
Recording frequency (fs) : 10 (Hz) Recording duration (duration) : 1024 (second). This is a one burst duration. Pressure sensor height from bed (heightfrombed) : 0.0 (m). Sensor located on the bed. Mean water depth (h) : 1.07 (m) |
