The Vistula is the Poland’s largest River. It flows from the south to the north and has its mouth in the Baltic Sea. Hydrographically the Vistula is divided into three sections: the Upper Vistula from the source to San tributary; the Middle Vistula up to the Narew tributary; and the Lower Vistula till the outlet to the sea. The Lower Vistula is 391 km in length. Along it there are several very important...
This article deals with a method of vessel position determination based on underwater information. The method consists in processing images produced by hydroacoustic systems. The system of bathymetric position determination can be a source of navigational information supplementary to satellite navigation, or the only source in most cases of submarine navigation. Information received from the second...
In order to provide for safe navigation we have to improve and automate the processes of vessel comunication and cooperation. This article proposes the formalization of these processes. Ontology is proposed as a supplement to the navigational information ontology. The authors present the possibility of implementing the ontology using the Maritime Information Markup Language (MIML) in an automated...
During autumn migration across the Central Mediterranean, adult Honey Buzzards cross the sea at its narrowest point, between western Sicily (southern Italy) and the Cap Bon Peninsula (Tunisia). This study investigated the influence of prevailing winds and geography on the orientation behaviour of migrants during this sea crossing by observations over two islands, one on the northern side, the other...
