The impact of hypothetical oil spills in Cyclades Islands (Aegean Sea, Eastern Mediterranean) is investigated by a reverse trajectory method whereby tracers have been back-tracked using surface current and wind data from 2013 to 2018. Results show that the westernmost islands of the archipelago (Kithnos, Kea, Andros) are at high risk all year round due to the proximity to the western oil tanker route (Bosphorus to Western Mediterranean). The arrival time of oil to these islands is less than 1 day, with the involvement of the entire perimeter of each island. The eastern islands are exposed to oil coming from the eastern oil tanker route (Bosphorus to Suez). In the summer, oil can reach the northern coast of Amorgos and Donousa in less than 1 day and Naxos in less than 2 days due to persistent ‘meltemi’ and induced surface current. Oil surveillance (for example by SAR) should focus all year round on the western route and on the eastern route north of the archipelago during the summer.

通过反向轨迹法调查了假设的漏油事件对基克拉迪群岛（爱琴海，地中海东部）的影响，使用2013年至2018年的地表电流和风向数据对示踪剂进行了追溯。结果表明，该群岛最西端的岛屿（基思诺斯（Kithnos），基亚（Kea）和安德罗斯（Andros））由于靠近西部油轮航线（博斯普鲁斯（Bosphorus）至西地中海（Mediterranean））全年都处于高风险。石油到这些岛屿的到达时间不到1天，而且每个岛屿的整个周边都参与其中。东部岛屿暴露于来自东部油轮航线（博斯普鲁斯海峡至苏伊士）的石油。在夏季，由于持续的“ meltemi”和诱发的地表电流，石油可以在不到1天的时间内到达Amorgos和Donousa的北部海岸，在不到2天的时间内可以到达Naxos。
