环流模型与拉格朗日颗粒跟踪模型耦合，用于在希腊爱琴海(地中海东部)输送漂浮的垃圾颗粒。考虑到不同的源区和释放日期，在考虑地表环流的季节和年际变化的情况下，对1990-2009年间漂浮凋落物的去向和分布进行了模拟。模型结果显示，北爱琴海高原、萨罗尼科斯湾以及埃维亚岛和克里特岛沿线的漂浮垃圾颗粒反复出现高浓度。模拟的漂浮落叶运输路径表明，来源区域是相互关联的，萨罗尼科斯湾是来自其他来源的落叶的主要接受者。值得注意的是，凋落物出口的百分比(~35%)高于进入模型域的百分比(~7%)，这表明爱琴海似乎是东地中海漂浮凋落物污染的来源而不是接受者。搁浅的垃圾约占10%，大部分位于爱琴海西部。这是第一个探索漂浮海洋垃圾在希腊水域运输的模型研究。
A circulation model is coupled to a Lagrangian particle-tracking model to transport floating litter particles in the Aegean Sea, Greece (Eastern Mediterranean). Considering different source regions and release dates, simulations were carried out to explore the fate and distribution of floating litter over 1990-2009, taking into account the seasonal and interannual variability of surface circulation. Model results depicted recurrently high concentrations of floating litter particles in the North Aegean plateau, the Saronikos Gulf, and along Evia and Crete islands. Modelled transport pathways of floating litter demonstrated that source regions are interconnected, with Saronikos Gulf being a main receptor of litter from other sources. Notably higher percent of litter exit (~35%) than enter the model domain (~7%) signified that Aegean Sea seems to act as a source rather than receptor of floating litter pollution in the Eastern Mediterranean Sea. Beached litter was found around 10%, mostly located in the western part of the Aegean Sea. This is the first modelling study to explore the transport of floating marine litter in Greek waters.
