Due to increased sea transport and offshore gas and oil exploration, the Arctic is facing an unprecedented risk of marine oil spills. Although beached oil spills can lead to acute and chronic impacts on intertidal ecosystems, the effects of oil spills on macro-algae in Arctic ecosystems is lacking. Here, we assessed the effect and response of the tidal macro-algae Fucus distichus to oiling, i.e. self-cleaning potential by seawater wash and photosynthetic activity. Oiling with four oil types (ANS, Grane, IFO30 and MGO) was simulated by exposing F. distichus tips to oil. Oil removal half-times ranged between 0.8 - 4.5 days, indicating that oiling of macro-algae with the tested oils was short-term. Further, Grane oil mostly inhibited photosynthetic activity whereas oil from ANS, IFO30 and MGO stimulated it. The photosynthetic activity of F. distichus continued to be affected (inhibited or stimulated), even after oil on the tip surface was washed off.
由于海上运输和近海天然气及石油勘探的增加，北极地区正面临着前所未有的海洋石油泄漏风险。尽管海滩溢油会对潮间带生态系统造成急性和慢性影响，但北极生态系统中大型藻类受到石油泄漏的影响仍缺乏研究。在此，我们评估了潮汐大型海藻厚叶马尾藻对油污的响应，即通过海水冲洗和光合作用来实现自我清洁的潜力。通过将 F. distichus 的尖端暴露于四种油类（ANS、Grane、IFO30 和 MGO）中来模拟油污。油污的去除半衰期在 0.8-4.5 天之间，表明受测试油类的大型藻类油污是短期的。此外，Grane 油类大多抑制光合作用，而来自 ANS、IFO30 和 MGO 的油类则刺激光合作用。即使尖端表面的油污已被冲洗掉，F. distichus 的光合作用仍持续受到影响（受到抑制或刺激）。
