This report by Lars R. Hole (Norwegian Meteorological Institute) provides a brief description of three oil spill modelling tools that are developed and in use in the Northern Periphery and Arctic region countries: Seatrack Web, OSCAR and OpenDrift. In addition, some examples of how these applications can be used are provided.

The report focuses on the first stage of situational development with oil spill accidents − detection. Before boom installation and response operations, a great deal of information needs to be collected. Firstly, one needs to know for sure, whether an oil spill accident occurred or not. If it did, then - where, when and how it happened? What is the scale of it, volume, oil type, slick dimensions on water surface, and direction of the slick movement? This report offers a good understanding on everything about applied models and the information they need and produce for the detection phase.
