Pollution incidents can be clearly visible. Around bays and headlands, strong local variations often perilous to mariners can be identified. Image Processing Sea and Space provides image data and processing facilities on this server. In the past, the star charts provided amazingly accurate navigation to mariners. Like the old star charts, they work by triangulation.
Water is ubiquitous on Earth.
For the ancients, it was one of the four primal elements of the Universe. Astronomers in our time have detected traces of water even in deep space. The water cycle on Earth is fundamental to life, and its study hydrology is a science in itself. But that is only half the story. We hope you will find new and exciting ways to use this medium in your work, both to prepare and to publish it.
