Marine debris composition, density, abundance, and accumulation were evaluated in salt marshes in Carteret County, North Carolina seasonally between 2007 and 2009. We assessed relationships between human use patterns and debris type. Wave effects on marine debris density were examined using a GIS-based forecasting tool. We assessed the influence of site wave exposure, period, and height on debris quantity. Presence and abundance of debris were related to wave exposure, vegetation type and proximity of the strata to human population and human use patterns. Plastic pieces accounted for the majority of all debris. Small debris (0-5 cm) was primarily composed of foam pieces and was frequently affiliated with natural wrack. Large debris (>100 cm) was encountered in all marsh habitat types surveyed and was primarily composed of anthropogenic wood and derelict fishing gear. Marsh cleanup efforts should be targeted to specific habitat types or debris types to minimize further damage to sensitive habitats.
2007 年至 2009 年期间,我们对北卡罗来纳州卡特雷特县的盐沼进行了季节性调查,评估了海洋垃圾的组成、密度、丰度和积累情况。我们评估了人类使用模式与垃圾类型之间的关系。利用基于 GIS 的预测工具研究了波浪对海洋垃圾密度的影响。我们评估了地点波浪暴露、周期和高度对垃圾数量的影响。垃圾的存在和丰度与波浪暴露、植被类型以及地层与人的种群和人类使用模式的接近程度有关。塑料碎片占所有垃圾的大部分。小碎片(0-5 厘米)主要由泡沫碎片组成,经常与天然碎屑有关。大碎片(>100 厘米)在所有调查的沼泽生境类型中都有发现,主要由人为木材和废弃渔具组成。沼泽清理工作应该针对特定的生境类型或垃圾类型,以尽量减少对敏感生境的进一步破坏。
