沿海岸线上来自当地陆地和远端海洋来源的海洋（塑料）碎片堆积是一个紧迫的现代问题。迄今为止，通过海滩调查评估污染源的相对贡献在方法上具有挑战性。我们调查了阿鲁巴（南加勒比海）背风和逆风海岸线的10个海滩，以确定宏观和中观碎片密度的差异。采用三个指标量化差异：1)远离滨水区的宏观碎屑密度梯度；2)宏观碎屑中塑料的比例；3)细观：宏观碎屑比。总共收集了42,585个宏观碎片和884个细观碎片。迎风岸线近岸宏观碎屑密度、塑性碎屑比例和中宏观碎屑比最高。这些结果表明，南加勒比迎风海岸线主要暴露于来自远端海洋来源的碎屑，而背风海岸线主要暴露于当地陆基来源的碎屑。我们的度量清楚地反映了这些差异，为调查碎片来源提供了新的方法。
Accumulation of marine (plastic) debris from local land-based and distal marine-based sources along coastlines is a pressing modern issue. Hitherto, assessing the relative contribution of pollution sources through beach surveys is methodologically challenging. We surveyed ten beaches along the leeward and windward coastlines of Aruba (southern Caribbean) to determine differences in macro- and meso-debris densities. Differences were quantified using three metrics: 1) the gradient in macro-debris density away from the waterfront; 2) the proportion of plastic within macro-debris; 3) the meso-:macro-debris ratio. Overall 42,585 macro-debris items and 884 meso-debris items were collected. The density of near-shore macro-debris, proportion of plastic debris herein, and meso-:macro-debris ratio were highest on the windward coastline. These results suggest that southern Caribbean windward coastlines are mainly exposed to debris originating from distal marine-based sources, and leeward coastlines to local land-based sources. Our metrics clearly reflect these differences, providing novel means to survey debris source origin.
