SP: Hydrometeoizdat, 2000. — 92 s. Basic information from the field of methods of oceanographic information processing using a personal computer is presented. The book does not claim a comprehensive coverage of the issue, which is one of the extensive, dynamically developing sections of experimental oceanography and is at the "connection" of various fundamental and applied disciplines. It provides an opportunity to test the knowledge gained by answering control questions and completing practical tasks. The first chapter is devoted to the description of the main sensing devices currently used in the practice of expeditionary oceanographic research in Russia and abroad. The second and third chapters consider the current methods of assimilation, storage and operational use of oceanographic information obtained during expedition studies and methods of their processing using computer technologies. Chapter 4 addresses issues related to the use of the World Wide Web for oceanographic research. This book is intended for students and graduate students of hydrometeorological specialties, and may also be of interest to oceanologists who turn in their professional activities to the issues of data management and their visualization.
