Abstract Post-war marine munition dumpsites do exist and are acknowledged by authorities, but their real extent and their effect onto the environment are mostly unknown. Military historic reconstruction and ocean current data (from in-situ measurements and modelled data) indicate that the German dumpsite in the Baltic Sea ‘Kolberger Heide’ is an active environment with a huge content of discarded munition material (DMM). Repeated high-resolution multibeam and underwater video surveys prove that Kolberger Heide contains more than 1,000 munition objects in the form of e.g. moored mines, ground mines, torpedoes and aerial bombs. An unsupervised seafloor classification was performed to show that corroded munition objects and proud explosives are in direct contact with the diverse local marine flora and fauna. Also the fact that the dumpsite is in close proximity to the shore in very shallow water (less than 15 m water depth) and displacement and burial of mines can be observed, demand an effective and standardised monitoring procedure. Via the combined approach of hydroacoustic and optical methods, areas can be identified, which should be prioritized when it comes to monitoring.

探索德国基尔湾的 Kolberger Heide 弹药堆放场：标准化水声和光学监测方法示例

摘要 战后海洋弹药垃圾场确实存在并得到当局承认，但其真实范围及其对环境的影响大多未知。军事历史重建和洋流数据（来自现场测量和模型数据）表明，波罗的海的德国垃圾场“Kolberger Heide”是一个活跃的环境，含有大量废弃弹药材料 (DMM)。重复的高分辨率多波束和水下视频调查证明，Kolberger Heide 包含 1,000 多个弹药对象，例如系泊地雷、地雷、鱼雷和航空炸弹。进行了无人监督的海底分类，以表明被腐蚀的弹药物体和引以为豪的爆炸物与当地多样化的海洋动植物群直接接触。此外，由于垃圾场靠近海岸，处于非常浅的水域（水深小于 15 m）并且可以观察到地雷的位移和掩埋，因此需要有效和标准化的监测程序。通过水声和光学方法的组合方法，可以确定区域，在进行监测时应优先考虑这些区域。
