Iranian Scientists Make 1st Directional Wave Recorder
“Knowing various phenomena, including the weather, the wave, the current regime and other natural phenomena requires field data collection with access to up-to-date and accurate equipment; therefore, for this purpose, the first directional wave recorder was designed and built with the aim of understanding the wave regime of marine and oceanic environments,” Seyed Massoud Mahmoudov, a member of the National Research Institute of Oceanography and the executive of the first directional wave recorder project.
Using this device, we will be able to extract the two-dimensional spectrum of waves. This device has gone through its initial testing period and has reached a stage where it is going to be launched in the sea for the first time and the main tests will be carried out in the Southern coasts of the country and the Caspian Sea,” he added.
Mahmoudov explained that the device was made in collaboration with the University of Science and Technology in Tehran.
The basic principles of wave measurement rely on the understanding that a wave is not a single defined entity, but the result of a series of individual waveforms superimposed on top of each other, all with different wavelengths, frequencies and amplitudes. Measurement of the wave activity therefore requires measurement of the pressure (and current) variations for a period of time, then “decomposing” the pattern into the constituent waveforms before analysing them and interpreting the data as a set.
The directional wave recorder calculates the direction from which the waves are coming by measuring the current oscillations caused by wave motion.
