This is a summary of the Norwegian report "Utforsking av brønnen ved Jomfrutårnet" by Ronny Andersen. Fin the Norwegian report here. This is an extract of the daily log from September 12th 2017, where Blueye was a used as a tool to explore the hidden tunnels in the well.
By the well house, we get ready to deploy the Blueye underwater drone (mini ROV), with support from Martin Ludvigsen from Norwegian University of Science and Technology (NTNU)
With calm movements, Martin drives the drone into the tunnel. It's pitch dark, but with the bright lights of the drone it is possible to get a good overview of the first room. The drone is approaching the narrow opening and the excitement is increasing as we start to enter the narrow passage into the next section.
Martin aims for the hole and flies through it. As the drone enters the new room, the visibility decreases, but it does not take long before we recognize that this room is much larger than the previous one. The floor and walls are gradually floating into each other, so it's hard to tell where the wall ends. But as the drone continues into the room, the walls come closer and form a narrow tunnel again.
After driving a couple for more meters, the tunnel is sealed with broken pieces of pipes and Tiling stones. The Blueye Pioneer has fully discovered new territory that had been inaccessible for many hundred years.
The drone turns around, and follows the yellow tether back to the entrance of the tunnel system.
The Blueye Pioneer has fully discovered new territory that had been inaccessible for many hundred years. This project could not have been more successful!
