How alarming are the ammunition remnants of two world wars still lying in old wrecks at the bottom of the North Sea and other seas? The EU-funded international project "North Sea Wrecks" investigated these questions, diving to wrecks in the North Sea, taking samples and analysing them. In a symposium on 19 and 20 April 2023 at the Alfred Wegener Institute, the project partners now presented the results. For more information, see this press release from the German Maritime Museum (DSM), which led the project.

However, night-time, reduced visibility (rough seas, fog, rain, etc.) or observer fatigue and distraction all limit the reliability of visual monitoring [...] commercial, cooled 360° thermal imaging sensor. After more than 10 years of research ashore and at sea, we captured thousands of whale cues (mostly blows and bodily displays) on video and analysed the data [...] environmental conditions (fog being the major impediment). Based on this comprehensive operational at-sea experience, we reframed our Tashtego software and are now in the final stages of finishing the most
