Um método de medição óptica de ondas superficiais de gravidade é desenvolvido e aplicado para ondas regulares bimodais. O método consiste na análise dos padrões espaciais e temporais do brilho no plano da imagem ao longo de uma sequência d

Dispersion of a passive tracer by water waves is of significant importance for many scientific and technological problems including bio-diversity of marine life, ecological impact of anthropogenic incidents, planning of rescue operation and global oc

It is well known that the majority of buoy measurements are located around the US coast and along some Europeans countries. The lack of long-term and densely spaced in situ measurements in the Southern Hemisphere in general, and the South Atlantic in

The automatic detection of passive tracers on a moving wavy surface has numerous applications in mathematics and engineering. In oceanography, among many examples, down-looking conventional optical cameras can be employed in wave tanks to investigate

Ocean waves forced by the wind are multidirectional, even if the wind direction is steady. Directionality can occur due to superposition of long-crested waves propagating at angle to each other. Lateral modulation of the wave crests, however, also ta

A new optical technique is presented and applied to measure regular, bichromatic surface waves propagating in different directions in a tank. The method is based on the patterns of spatio-temporal variations of brightness over sequential frames. A si

Contrary to the widely held notion that considers the occurrence of freak waves in the ocean as being rare, from an examination of five years of wave measurements made in the South Atlantic Ocean, we found the occurrence of freak waves is actually mo
