Tirpitz Site Project
During WWII, the Tirpitz posed a significant threat to Arctic and was repeatedly attacked by the Royal Navy and Royal Air Force, and Soviet Air Force. Finally sunk in 1944 by the Royal Air Force, the ship´s remains were then salvaged with vast amounts of non-commercial material being dumped on the seabed. The Arctic Legacy of War, Tirpitz Site Project is utilising remote sensing and aerial and underwater robots. It is a multidisciplinary endeavour that includes science, technology, archaeology and historical research to record and monitor the site. This will be used to consider the site's heritage values, and evaluate the environmental risks posed by this legacy of war.

The orthoimage, with a spatial resolution of 2.5 cm, will be used for a bathymetric map to accurately estimate the area covered by the Tirpitz debris.

Image acquisition: Markus Dreyer, aerial images; Martin Bjørndahl, supporting underwater images (UiT The Arctic University of Norway).
