论文摘要
数十年来，源自人类活动的海洋碎片一直在海洋，湖泊和河流等水下环境中积累。由于无法理解散布的确切机制，因此很难评估废物的程度，类型和数量，从而对海洋环境和人类健康产生了未知的后果。因此，用于检测和映射海洋碎片的方法对于洞悉污染动力学至关重要，而污染动态又可以用来有效地计划和执行物理去除。使用配备了水下高光谱成像仪（UHI）和立体声相机的自动驾驶水下车辆（AUV），在挪威卑尔根贝尔根（Bergen）的庇护海湾商店Lungegaardsvann中自主检测，映射和量化了海洋碎片。
Marine debris originating from human activity has been accumulating in underwater environments such as oceans, lakes, and rivers for decades. The extent, type, and amount of waste is hard to assess as the exact mechanisms for spread are not understood, yielding unknown consequences for the marine environment and human health. Methods for detecting and mapping marine debris is therefore vital in order to gain insight into pollution dynamics, which in turn can be used to effectively plan and execute physical removal. Using an autonomous underwater vehicle (AUV), equipped with an underwater hyperspectral imager (UHI) and stereo-camera, marine debris was autonomously detected, mapped and quantified in the sheltered bay Store Lungegaardsvann in Bergen, Norway.
