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.

Earth scientists describe a new kind of volcanic eruption

The eruption and volcanic material sedimentation processes of giant caldera eruptions are not well understood, making it also difficult to estimate their size. Kobe University researchers used seismic reflection surveys to visualize the sedimentary structure and analyzed collected sediment samples, enabling them to obtain important information on the distribution, volume, and transport mechanisms of the ejecta. © SHIMIZU Satoshi (CC BY)
