Increased knowledge about the fate and behaviour of weathered oil in different sea ice conditions is essential for our ability to model oil spill trajectories in ice more precisely and for oil spill response decision making in northern and Arctic areas. As part of the 3-year project: "Fate, Behaviour and Response to Oil Drifting into Scattered Ice and Ice Edge in the Marginal Ice Zone", a novel wave and current flume was built to simulate these processes in the laboratory. This paper discusses some of the findings from this project, which included Marine Gas Oil and four Norwegian crude oils. All crude oils were weathered prior to testing, simulating having drifted on the sea surface for a period (tentatively 1-3 days) before encountering ice. The build-up of oil drifting against an ice barrier and horizontal and vertical migration of oil droplets under solid ice and in frazil ice was studied.
增加对不同海冰条件下风化石油的命运和行为的了解，对于提高我们在冰区更精确地模拟溢油轨迹的能力以及在北方和北极地区进行溢油应急决策至关重要。作为为期 3 年的项目“漂移至边际冰区分散冰和冰缘的石油的命运、行为和应对”的一部分，建造了一个新的波浪和水流水槽，以在实验室中模拟这些过程。本文讨论了该项目的一些发现，其中包括 Marine Gas Oil 和四种挪威原油。所有原油在测试前都进行了风化，模拟在遇到冰之前已经在海面上漂移了一段时间（暂定 1-3 天）。研究了油在冰障上的堆积以及油滴在固体冰和碎冰下的水平和垂直迁移。
