Remote sensing

Abstract

Management of the marine environment and its resources according to the ecosystem approach represents a tremendous increase in demand for quality data. This is needed for establishing correct understanding of ecosystem dynamics and is essential for precise assessment of state and development of ecosystem components, particularly those associated with human exploitation. Adequate information for these purposes is obtainable only if we can be present at the time when and location where processes take place. Such objectives strongly contrast those of current monitoring strategies. These are often based on snapshot pictures of the state at regular temporal distance as recorded by standardized surveys. Is it possible to adjust current approaches to satisfy future demands? What is the realism costwise? What are the alternatives?.
