Contemplating Ocean Wave Measurements
This is a personal contemplation on the state of ocean wave measurement, historically, and with an eye toward the future. The conceptual basis which leads to the conventional wave measuring instruments has been in practice for over six decades which is basically single point observations of three-dimensional waves. We need new conceptual advancement and new instrumentation to rejuvenate our res...
متن کاملAn Empirical Imaging Model for Sar Ocean Wave Measurements
Continuous ocean wave measurements on a global basis are still only possible using spaceborne synthetic aperture radar. For more than a decade the European satellites ERS-1 and ERS-2 have acquired about 1500 globally distributed SAR images dayly. ENVISAT is capable of recording some 3000 imagettes. However strong uncertainties in the SAR ocean wave imaging models used so far are well known. The...

متن کاملOpen Ocean Surface Wave Measurement Using Doppler Sonar
In October-November 1983, Doppler sonars mounted on the research platform Flip were used to scatter 75-kHz sound from the underside of the sea surface at low angle, as well as from the interior of the mixed layer. Surface gravity waves were seen in velocity estimates from the surface scattering sonar, even though the wave conditions were unusually calm. Valid measurements of sea surface motion ...
متن کاملProgress in ocean wave forecasting
Progress in ocean wave forecasting is described in the context of the fundamental law for wave prediction: the energy balance equation. The energy balance equation gives the rate of change of the sea state caused by adiabatic processes such as advection, and by the physical source functions of the generation of ocean waves by wind, the dissipation due to whitecapping and the nonlinear four-wave...
