在塑料和全球环境问题的时代，当在主要海洋盆地观察到大片垃圾斑块时，这项工作是首次尝试探索地中海可能存在类似永久堆积结构的可能性。这项工作解决的问题是：具有子流域尺度环流和中尺度不稳定性的大气环流能否促进某些地区漂浮物的集中？哪里的沿海地区更有可能受到公海来源的影响？对平流表面被动碎片的多年模拟将第勒尼安海、西北地中海次盆地和苏尔特湾描述为可能的滞留区域。地中海西部海岸的海岸影响非常小，而从突尼斯到叙利亚的沿海地带似乎是最受欢迎的目的地。由于盆地环流变化带来了足够的异常现象，因此没有发现能够长期保留漂浮物的永久性结构。 (C) 2014 Elsevier Ltd. 保留所有权利。
In the era of plastic and global environmental issues, when large garbage patches have been observed in the main oceanic basins, this work is the first attempt to explore the possibility that similar permanent accumulation structures may exist in the Mediterranean Sea. The questions addressed in this work are: can the general circulation, with its sub-basins scale gyres and mesoscale instabilities, foster the concentration of floating items in some regions? Where are the more likely coastal zones impacted from open ocean sources?Multi-annual simulations of advected surface passive debris depict the Tyrrhenian Sea, the north-western Mediterranean sub-basin and the Gulf of Sirte as possible retention areas. The western Mediterranean coasts present very low coastal impact, while the coastal strip from Tunisia to Syria appears as the favourite destination. No permanent structure able to retain floating items in the long-term were found, as the basin circulation variability brings sufficient anomalies. (C) 2014 Elsevier Ltd. All rights reserved.
