… results are presented for a non-intrusive optical wave gauge based on the principle of optical triangulation. In the proposed implementation, a LASER source beaming vertically downwards generates a spot of scattered light at the water surface. The spot is imaged by an off-axis video camera, and instantaneous wave height measurements are obtained by processing of the spot images. The spot position on the image is then transformed into a height value using …

… In some shelf sea regions of the world, the tidal range is sufficient to convert the potential energy of the tides into electricity via tidal range power plants. As an island continent, Australia is one such region – a previous study estimated that Australia hosts up to 30% of the world’s resource. Here, we make use of a gridded tidal dataset (TPXO9) to characterize the …
