      <title>Emission Inventory of Marine Traffic for the Port of Šibenik</title>
      <link>https://trid.trb.org/View/1758948</link>
      <description><![CDATA[The paper estimates the exhaust emissions of marine traffic in the port of Šibenik. The results of the analysis were obtained by including the following gaseous pollutants: nitrogen oxide (NOX), sulphur oxide (SOX), particulate matter (PM), volatile organic compounds (VOCs) and carbon dioxide (CO2) as greenhouse gas. In order to gain results and estimate the emission of harmful gases in the port of Šibenik, the passenger and the cargo throughput were taken into account. The activities of the ship during which the exhaust gases are emitted into the atmosphere are slow cruising in the reduced speed zone, manoeuvring and hotelling. The “bottom-up” method used in the emission estimation takes into account the ship’s engine power, engine load factor, fuel type, the emission factor, time of cruising and time hotelling in the port of Šibenik. The results of the analysis have shown that approximately 70 % of total emissions come from passenger ships (cruise ships) and 30 % from cargo ships.]]></description>

      <title>Marine accident risk assessment for Port of Šibenik area</title>
      <link>https://trid.trb.org/View/1441123</link>
      <description><![CDATA[Šibenik is a large and one of the oldest and best protected natural harbor on the Croatian Adriatic coast. The Old Port is located in the submerged estuary of the river Krka. Limited available room for maneuvring within the harbour, new passenger terminal and part of the port for handling different types of cargo reduce the space for safe navigation and mooring/ unmooring of merchant and cruise ships. Approach to the port of Šibenik from the open sea, especially the navigation through St. Anthony channel and maneuvering inside the waters of the city port present a particular challenge to each seafarer. As far as safety is concerned, the mentioned circumstances significantly contribute to increasing the threat of possible maritime accidents. Therefore, there is a need to evaluate the potential threats of maritime accidents in the Šibenik St. Anthony channel. To determine the threat of maritime accidents a qualitative method was used: ranking of threats. Each maritime accident in the narrow area of the St. Anthony channel and the port of Šibenik could result in severe consequences on the overall economic and other activities of the port of Šibenik. St. Anthony channel is the only entrance into the central Dalmatian town of Šibenik and international port of Šibenik. Because of its characteristics, the length which is not in a straight line, it is necessary to frequently change course at shorter intervals. Channel width in some places is reduced and causes problems, and due to sea currents and occasional strong winds, the channel is from the point of safe navigation very difficult for navigation. Moreover, passing ships over 50 GT within the channel is dangerous. The possibility of a collision, grounding and/ or sinking of large ships during transit through the St. Anthony channel may eventually lead to a complete closure of maritime passenger and freight traffic to the port of Šibenik. It is therefore of utmost importance to assess the threat of a collision, grounding and/ or sinking of ships in the waters of the port of Šibenik. .]]></description>

      <title>Spatial Distribution of Uranium and Radium in the Sediments, Musels (Mytilus sp.), and Sea Water in Port of Sibenik</title>
      <link>https://trid.trb.org/View/788541</link>
      <description><![CDATA[This article reports on a study undertaken to assess the response of the aquatic environment (sediment, seawater and mussels Mytilus sp.) to uranium and radium activity and concentration following the decrease of phosphate discharges from a technologically improved transshipment terminal, located at the Croatian Adriatic coast in the port of Sibenik.  The highest uranium and radium activities were found in the sediment sample collected from the sampling site closest to the terminal.  The authors conclude that since the transshipment terminal in the port of Sibenik was modernized in the 1980s, the discharges of the phosphate ore into the seawater was drastically reduced and, consequently, uranium concentration levels in the seawater decreased.  The enhanced uranium and radium activity levels are found only in the sediment near operational docks, and in the mussels which live on these docks.  Mussels sampled below the operational dock showed levels of uranium activities several times higher than in the consumable mussels a few kilometers upstream and downstream, while activities of radium are uniform.  These enhanced uranium levels in mussels near the operational docks are present due to the diminished, but constant, input of phosphate particles from the docks into the estuarine environment and from the dissolving of uranium from the sediment.  Uranium concentration levels in the seawater samples are consistent with values for unpolluted environments.]]></description>
