In this study, we estimated the variety and distribution of macroplastics in the central part of Spitsbergen, Svalbard archipelago, Arctic. All marine litter photos were georeferenced, then identified using the OSPAR (2010) classification guide. The majority (90% of all objects) of marine debris was macroplastic with average number in the study area being 2.0 ± 0.4 objects per 100 m. It was determined that the full variety of macroplastic categories in the study area can be found after surveying approx. 8 km of coastline. Correlation analysis showed that the amount of macroplastic accumulated on the beaches decreases with distance from the open ocean and increases with wave fetch. When zoning the entire study area on the basis of a cluster analysis of the distribution of macroplastics, it was found that the geographical proximity of the sections is less important than the wave fetch.
在本研究中，我们估算了斯瓦尔巴群岛中部（斯匹次卑尔根），北极地区的海洋中大型塑料的种类和分布。所有海洋垃圾的照片都经过地理定位，然后使用 OSPAR（2010 年）分类指南进行识别。海洋碎片的大部分（所有物体的 90%）是大型塑料，研究区域的平均数量为每 100 米 2.0 ± 0.4 个物体。经调查发现，研究区域内完整的大型塑料类别可以在大约 8 公里的海岸线上找到。相关分析表明，海滩上积累的大型塑料数量随离开阔海域的距离的增加而减少，随波浪推进距离的增加而增加。当根据大型塑料分布的聚类分析对整个研究区域进行分区时，发现各部分的地理位置接近程度不如波浪推进距离重要。
