Marine litter has become a worldwide environmental problem, tainting all ocean habitats. The abundance, distribution and composition of litter and its interactions with fauna were evaluated in the upper S. Vicente canyon using video images from 3 remote operated vehicle exploratory dives. Litter was present in all dives and the abundance was as high as 3.31 items100m(-1). Mean abundance of litter over rock bottom was higher than on soft substrate. Mean litter abundance was slightly higher than reported for other canyons on the Portuguese margin, but lower in comparison to more urbanized coastal areas of the world. Lost fishing gear was the prevalent type of litter, indicating that the majority of litter originates from maritime sources, mainly fishing activity. Physical contact with sessile fauna and entanglement of specimens were the major impacts of lost fishing gear. Based on the importance of this region for the local fishermen, litter abundance is expected to increase.
海洋垃圾已成为一个全球性的环境问题，污染了所有的海洋栖息地。利用遥控潜水器进行的3次探索性潜水所拍摄的视频图像，对圣维森特峡谷上游垃圾的丰度、分布、组成及其与动物的相互作用进行了评估。所有潜水区域均发现有垃圾，其丰度高达每100米3.31件。岩石底部的垃圾平均丰度高于软质海底。垃圾的平均丰度略高于葡萄牙海域其他峡谷的报告值，但与世界上城市化程度更高的沿海地区相比则较低。丢失的渔具是最常见的垃圾类型，这表明大多数垃圾源自海洋来源，主要是渔业活动。与固着动物的身体接触和标本的缠绕是丢失渔具造成的主要影响。鉴于该地区对当地渔民的重要性，预计垃圾丰度将会增加。
