Among the numerous hydrothermal mounds of the Jøtul field is the Nidhogg spring, named after a serpent-like dragon in Norse mythology that lives on the world tree Yggdrasil. The fluids with temperatures of 40 to 50 degrees Celsius at Nidhogg lead to the precipitation of barite and amorphous opal, and the numerous amphipods particularly like these temperatures.
