Applications of Optics in Oceanography focuses on the emerging tools of optics, which are being used to observe, study, understand, and model a plethora of oceanographic processes that fall into and cross the various oceanograhic subdisciplines. Optical sensors provide important information for a host of important oceanographic study areas. These include ocean physics, phytoplankton, biogeochemistry, and sediments among many others. Likewise, the increased understanding of light and its interaction with the ocean medium has led to advances in oceanographic theories, again spanning the subdisciplines. Our intent is to provide a starting point for students, researchers, technologists, technicians, and applied oceanograhers, who would like to learn more about the optics of the ocean and how to apply and utilize optical methods and theories. The book can be used for special topics classes or summer programs in areas such as bio-optical oceanography, harmful algal blooms, coastal pollution, ocean colour remote sensing, radiative transfer in the ocean, primary productivity, ocean monitoring and observing systems, and ocean ecology and biogeochemistry. It is also intended to be useful for specialists in ocean optics, who are interested in a wide variety of interdisciplinary applications. It can be used by those who have little knowledge of optics, but wish to capitalize on the power of new optical methods and models. To our knowledge, this is the first book to focus primarily upon the application of optics to oceanography.
