The book describes experience in application of coastal altimetry to different parts of the World Ocean. It presents the principal problems related to the altimetry derived products in coastal regions of the ocean and ways of their improvement. This publication is based on numerous satellite and observational data collected and analyzed by the authors of the various chapters in the framework of a set of international projects, performed in UK, France, Italy, Denmark, Russia, USA, Mexico and India. The book will contribute both to the ongoing International Altimeter Service effort and to the building of a sustained coastal observing system in the perspective of GMES (Global Monitoring for Environment and Security) and GEOSS (Global Earth Observation System of Systems) initiatives. This book is aimed at specialists concerned with research in the various fields of satellite altimetry, remote sensing, and coastal physical oceanography. The book will be also interesting for lecturers, students and post-graduate students.
