The upper part of this TerraSAR-X image of Sydney shows Botany Bay, located south of the airport. In the lower right section is Bate Bay. The rough sea rolling towards the coastline from the Tasman Sea is clearly visible. In the open water the waves have a length of about 150 metres. They become shorter as they enter shallower waters, and finally break as they hit the coastline. The image also shows so-called diffraction effects, which indicate a change in wave pitch (to be seen at the lower centre of the image). This effect is also related to the change in water depth. Two-dimensional images of wave fields in such a high resolution are of great interest for a variety of coastline management and shipping applications.
