Abstract The Norwegian Arctic covers Svalbard, Bear Island, Jan Mayen and the Barents Sea. 80% of all shipping activities in the Arctic are within Norwegian territorial waters and the Exclusive Economic Zone. To reduce the risk for accidents, the Norwegian authorities have established several preventive measures. Among these are ship reporting systems, traffic separation schemes in international waters and surveillance capabilities. If an accident has occurred and an oil spill response operation must be organized - resources, equipment, vessels and manpower from Norwegian and neighboring states will be mobilized. In 2015, the Norwegian Coastal Administration finalized an environmental risk-based emergency response analysis for shipping incidents in the Svalbard, Bear Island and Jan Mayen area. This scenario-based analysis has resulted in a number of recommendations that are currently being implemented to be better prepared for oil spill response operations in the Norwegian Arctic. Further, a large national oil spill response exercise in 2016 was based on one of these scenarios involving at sea and onshore oil spill response at Svalbard. The 2016 exercise, working within the framework of the Agreement on Cooperation on Marine Oil Pollution Preparedness and Response in the Arctic between Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the USA (Arctic Council 2013), focused on a shipping incident in the Norwegian waters in the Barents Sea, close to the Russian border. Every year, as part of the Russian – Norwegian Oil Spill Response Agreement and the SAR Agreement in the Barents Sea, combined SAR and oil spill response exercises are organized. These are held every second year in Russia and every second year in Norway. There is an expected increased traffic and possible increased risk for accidents in the Arctic waters. In order to build and maintain an emergency response system to this, cooperation between states, communities, private companies and other stakeholders is essential. It is important that all actors that operate and have a role in the Arctic are prepared and able to help ensure the best possible emergency response plans. We depend on one another, this paper highlights some of the ongoing activities designed to strengthen the overall response capabilities in the Arctic.

Increasing exploration and exploitation activity in the Arctic Ocean has intensified maritime traffic in the Barents Sea. Due to the sparse population and insufficient oil spill response infrastructure on the extensive Barents Sea shoreline, it is necessary to address the possibility of offshore accidents and study hazards to the local environment and its resources. Simulations of surface oil spills were conducted in south-east of the Barents Sea to identify oil pollution trajectories. The objective of this research was to focus on one geographical location, which lies along popular maritime routes and also borders with sensitive ecological marine and terrestrial areas. As a sample of traditional heavy bunker oil, IFO-180LS (2014) was selected for the study of oil spills and used for the 30-year simulations. The second oil case was medium oil type: Volve (2006)—to give a broader picture for oil spill accident scenarios. Simulations for four annual seasons were run with the open source OpenDrift modelling tool using oceanographic and atmospheric data from the period of 1988–2018. The modelling produced a 30-year probability map, which was overlapped with environmental data of the area to discuss likely impacts to local marine ecosystems, applicable oil spill response tools and favourable shipping seasons. Based on available data regarding the environmental and socio-economic baselines of the studied region, we recommend to address potential threats to marine resources and local communities in more detail in a separate study.

The paper grounds the necessity to conduct the large-scale field experiment on manoeuvring with the floodgates of Saint Petersburg Flood Protection Complex (FPC). The paper presents the results of I-stage experiment and the program of II-stage experiment. The aim of the experiment is the verification of the possibility to manage the hydrological, sanitary and ecological state of the Neva Bay and the eastern part of the Gulf of Finland of the Baltic sea by means of manoeuvring with Flood Protection Complex floodgates. In order to develop the program of field experiment implementation it was necessary to assess the sanitary and ecological state of water ecosystem under present conditions. The assessment was based on monitoring data concerning the certain priority parameters obtained from the selected representative measuring points. On the basis of the analysis of water quality and the state of the Neva Bay and the eastern part of the Gulf of Finland the scheme for manoeuvring with floodgates of the FPC together with the sequence of order of their opening and closing was developed. Recommendations regarding the conditions and terms of conducting the experiment were developed.
