A shipwreck discovered during a search for dumped wartime ammunition in Norway's Lake Mjøsa has been identified as a local "føringsbåt" from up to 700 years ago. But bad weather has prevented researchers from finding out more.
The wreck, which lies at a depth of around 1,300 feet (400 meters), was found in 2022 by an autonomous underwater vehicle (AUV) mapping the lake for Norway's military.
The discovery caught the attention of researchers at the Norwegian University of Science and Technology (NTNU) based in the city of Trondheim. But they were not able to revisit the wreck until last month.
