Digital Information System for the Polish Marine Areas - Modelling of Structures and Dynamics of Physical Processes in the Southern Baltic

Abstract

Researching the dynamic environment of the Baltic Sea requires an interdisciplinary approach, with numerical models and computer simulations becoming essential tools. The 3D CEMBS-PolSEA ecosystem model, developed at the Institute of Oceanology of the Polish Academy of Sciences, aims to determine the basic hydrodynamic parameters of the southern Baltic Sea. The CSI-POM service (Digital Information System on the Environment of Polish Marine Areas) consists of new tools for studying the structures, dynamics, and variability of physical processes in the southern Baltic. The service includes tools for determining the thermocline, halocline, and pycnocline, conducting spatio-temporal analysis of water column structure, automatic detection of vortices, testing water mass inertia under forecasted wind forces, and automatic detection of upwelling currents. The novelty of this work lies in the development of tools for studying the dynamics of the structure and variability of physical processes in the southern Baltic Sea. These innovative techniques support scientists, the maritime community, and regulatory bodies by providing detailed insights into local phenomena such as vortex formation, water mixing. The tools are implemented on the project server and the Tryton+ supercomputer, enabling high temporal and spatial resolution results. The CSI-POM system's operational mode ensures access to the latest model results, with real-time and forecasted data. This enhances understanding and forecasting capabilities, informing about the current state of the environment and potential threats in the open sea.
