对南极洲海洋废弃物的观测一直在增加，但对废弃物的影响、分布、来源和迁移途径仍然知之甚少。在这里，我们描述了2022/2023年南极帕尔默站附近海洋垃圾的空间分布，类型和潜在来源。我们偶然收集了135件海洋垃圾，大部分物品是在沿着海岸线上发现的（90%），一些是在海鸟巢/群落中/附近发现的（7%），很少有在内陆岩石地形上发现的（3%）。塑料和遗弃、丢失或丢弃的渔具占观察到的碎片的绝大多数。结果表明，风和南极沿岸流可能是碎片的主要路径。这项研究是对该区域海洋废弃物的第一次评估，表明海洋学、天气模式和海岸线地貌可以在确定废弃物将在何处积聚方面发挥作用。继续跟踪碎片和开展结构化调查对于了解人类活动对生物热点的影响十分重要。
Observations of marine debris in Antarctica have been increasing; however, impacts, distributions, sources, and transport pathways of debris remain poorly understood. Here, we describe the spatial distribution, types, and potential origins of marine debris in 2022/2023 near Palmer Station, Antarctica. We opportunistically collected 135 pieces of marine debris with the majority of items found along shorelines (90 %), some found in/near seabird nests/colonies (7 %) and few on inland rocky terrain (3 %). Plastic and abandoned, lost, or discarded fishing gear dominated observed debris. Results suggest that wind and the Antarctic Coastal Current may be a major pathway for debris. This study is the first assessment of marine debris in this region and suggests that oceanography, weather patterns, and shoreline geomorphology could play a role in determining where debris will accumulate. Continued tracking of debris and development of structured surveys is important for understanding the impacts of human activities in a biological hotspot.
