Przedstawiono potrzeby związane z wdrażaniem usług e-nawigacji. Dokonano też krótkiej analizy wymagań w zakresie pożądanych parametrów transmisyjnych systemów zdolnych do przenoszenia rosnącej ilości informacji wymienianych pomiędzy stacjami brzegowymi i statkami na morzu. Dokonano też krótkiego przeglądu szerokiego zakresu systemów wykorzystywanych na morzu. Sformułowano wnioski związane z potrzebą opracowania uniwersalnego i stosunkowo taniego systemu łączności z minimalnymi wymaganiami i stanowiącego sensowne uzupełnienie istniejących systemów. Przedstawiono potencjał aplikacyjno-wdrożeniowy i wskazano możliwe kierunki rozwoju systemu.

The article presents the needs related to the implementation of e-navigation services. A brief analysis of the requirements for the desired transmission parameters of systems capable of transferring the growing amount of information exchanged between shore stations and ships at sea was also made. A brief overview of the wide range of maritime communication systems has also been made. Conclusions related to the need to develop a universal and relatively cheap communication system with minimum requirements and constituting a reasonable complement to existing systems were formulated. Application and implementation potential was presented and possible directions of system development were indicated.

In recent years, modelling has been one of the fastest growing fields of science. Ocean, ice and atmospheric models have become a powerful tool that has supported many scientific fields during the last few decades. Our work presents the new operational service – called eBalticGrid – implemented into the PLGrid Infrastructure (Dziekoński et al. 2014). The grid is based on three modelling tools – an ocean model (Parallel Ocean Program), an ice model (Community Ice Code) and an atmospheric model (Whether Research and Forecasting Model). The service provides access to 72-hour forecasts for the Baltic Sea area. It includes the physical state of the Baltic Sea, its ice cover and the main atmospheric fields, which are the key drivers of the Baltic’s physical state. Unlike other services, this provides the additional three-dimensional fields of temperature, salinity and currents in the Baltic Sea. The models work in operational mode and currently one simulation per day is run. The service has been implemented mostly for researchers. Access to the results does not require any modelling knowledge. Therefore, the main interface between a user and the model results was designed as a portal providing easy access to the model’s output. It will also be a very suitable tool for teaching students about the hydrology of the Baltic Sea. Data from the system are delivered to another operational system – SatBaltic (Woźniak et al. 2011). The development of an output format to be suitable for navigational software (GRIB files) and sharing via FTP is also planned.

Breaking waves (whitecaps) are one of the most important and least understood processes associated with the evolution of the surface gravity wave field in the open sea. This process is the principal means by which energy and momentum are transferred away from a developing sea. However, an estimation of the frequency of breaking waves or the fraction of sea surface covered by whitecaps and the amount of dissipated energy induced by breaking is very difficult to carry out under real sea conditions. A controlled experiment, funded by the European Commission under the Improving Human Potential Access Infrastructures programme, was carried out in the Ocean Basin Laboratory at MARINTEK, Trondheim (Norway). Simulation of random waves of the prescribed spectra by wave makers provided a very realistic pattern of the sea surface. The number of breaking waves was estimated by photographing the sea surface and recording the noise caused by the breaking waves. The experimental data will serve for calibration of the theoretical models of the sea surface fraction related to the whitecaps.

Based on the experience acquired from working on the Regional Oceanographic Database (ROD) at the IOPAS in Sopot and from cooperation with similar scientific facilities, a general review of problems with the security of data ownership, copyrights, rendering the scientific information accessible, propagating it and differences in the access to data in European Union and Poland was presented. A system for accessing processed data, educational data and source information was proposed.
