    Positioning Functionality
    Opis:
    The paper discusses the ASG EUPOS services. There is presented an assessment of the possibility of using this system selected sites in hydrography and off-shore navigation tasks. Presented and analyzed the experiments were carried out in the port of Gdynia and on the Gulf of Gda?sk. The results obtaining in the work confirm the possibility of the position accuracy guaranteed by ASG EUPOS services. The obtained accuracy greatly exceeds the needs and requirements of coastal navigation and underwater mining and exploration of sea bottom.

    Opis:
    The primary purpose of the paper is to identify port areas most exposed to extreme hydrodynamic conditions (waves, sea currents, seabed level change). The results of modelling using SWAN wave model, MIKE 3D model, and reanalysis and measurement data were used in paper. Swell may exceed 0.8 m for winds exceeding 15 m s-1 from the west and south. During extreme conditions, sea currents can reach 0.4 ms-1 in the outer part of the bay adjacent to the port. Port basins do not show changes in the thickness of the seabed for the given maximum values of bottom currents. The most extensive deposition of the seabed and shore sediments (up to 0.04 m) is found on the Gdynia-Oksywie beach adjacent to the port and the approach fairway at the offshore currents. The outer area of the main breakwater is the most exposed to erosive activity (-0.012 m).

    Radar Tracking
    Opis:
    Detection of small crafts/targets, in particular, sailing yachts with the ship's radar is not always possible. Radar reflectors are used to improve their detection. The AIS (Automatic Identification System) transmits position, motion vector and identification signals of a vessel to other ships and VTS (Vessel Traffic Services) centers . This system significantly increases the possibility to detect small crafts. The paper presents results of comparative study of using information from the Automatic Identification System and from radar to determine the accuracy of tracking the position and motion vector of ships in the Gulf of Gdansk. Possibilities and limitations of the AIS are also presented.

    Opis:
    The paper discusses ships’ routes to Polish ports in the Gulf of Gdańsk determined on the basis of data obtained from the Baltic Ship Monitoring System by means of AIS coast stations and defined by the Baltic Sea Hydrographic Commission (BSHC). The measures to regulate maritime traffic implemented by the Polish maritime administration in order to reduce the identified risk of groundings and ship collisions are presented, as well as the author's opinion on their effectiveness.
