| contents | The German waters contain around 1.6 millions of tons of munition, mostly dumped after the world wars. Within Lübeck Bay (Baltic Sea) the majority of the munition is concentrated in the officially designated dumpsites (Munition Cadaster "AmuCad", EGEOS GmbH, www.amucad.org ). However, many individual items or piles are found outside of these areas. Most of the munition contain conventional explosives, primarily 2,4,6-trinitrotoluene (TNT), which is toxic and is known to cause cancer in various organisms in water solutions with concentration > 1 mg/l (Lotufo et l., 2017; Beck et al., 2018). The structure and composition of epifauna was investigated on the dumped munition in the previously unknown site using a remotely operated vehicle (BlueRobotics, model BlueROV2) during cruise AL622 with RV 'Alkor' on 19. October 2024. Nine individual munition objects and the surrounding sediment were observed in the central-northern Lübeck Bay at depth of 19-21 m at the area of ~500 m². Two videos have been made: the one of all objects filmed with the in-built camera; the second of six objects filmed with the additional GoPro3 camera, mounted on the ROV. Objects were identified as warheads from the Fieseler Fi 103 (known as V1) packed for transporting in additional metal carcass. The warheads are on a different stage of degradation. Their metal parts are covered with dense epifauna communities and bare explosives is mostly free from fouling. |
