Case studies on chemical munitions

DAIMON had a closer look on two dump locations with chemical warfare agents (CWA): Gdańsk Deep (Kolberger Heide) and Bornholm Deep. DAIMON's task was to precisely locate singular objects within the pilot areas by means of side scan sonars (SSS) supplemented by Magnetic Anomaly Detector (MAD), using both towed arrays and Autonomous Underwater Vehicles (AUV). Detected objects were inspected by Remotely Operated Vehicles (ROV), and identified based on visual data, archive inventory and other in situ methods. Sediment and water samples were collected to assess the spreading of toxic compounds. Passive samplers were deployed in vicinity of identified objects. Collected samples will be analyzed in regard to their impact on biota including infauna communities and fish.
