Abstract
The article discusses the basic principles of creating modern systems of operational oceanography. The set of basic principles is presented in the form of methodological foundations for constructing operation oceanography systems as applied to the tasks of underwater observation. The properties of such systems, which are fundamentally important for applications in the field of marine observation systems, are characterized. Some problematic issues are discussed. Links of operational oceanography tools to a number of applications are considered. Among the tasks, attention is paid to acoustic underwater observation, optical instruments and models, biochemical processes and models. Among the basic principles, one of the most important is the consistent integration of local models and systems into regional systems and further into global systems, as well as the interface between models and systems at different levels. Attachment and interface processes are accompanied by refinement of initial and boundary conditions using assimilation of in-situ data. The quality of the output results of applied systems depends on the quality of assessments of the state of the oceanic environment and is the basis for the presentation of requirements for the accuracy (uncertainty) of operational oceanography systems. The analysis of the sequential transfer of uncertainty from estimates of the ocean environment to the uncertainty in the output of applied underwater observation systems is also a basic principle. The consistency and practical usefulness of operational oceanography systems in underwater observation tasks are directly related to meeting the requirements coming from applications. The quality of operational oceanography systems is associated with the procedures of adaptive sampling of natural data and adaptive modelling.
