Iceland’s rootless volcanoes

Keri McNamara February 7, 2019

Rootless cones in Lake Mývatn, NE Iceland. These cones were formed when the Younger Laxá Lava inundated the lake approx. 2000 years ago. In total, there are over 1400 rootless cones around Mývatn, ranging in size from <2 m crater. Credit: Frances Boreham

Picture a volcano, like the one you learned about in primary school. Can you see it? Is it a big rocky mountain, perhaps with a bubbling pool of lava at the top?

It features the research vessel Heincke, on a remarkably calm and warm spring day, forming a seemingly steady wake. The roughly 55 metre long FS Heincke, owned by the German federal government and operated by the Alfred Wegener Institute, provides a great platform for local studies of the North Sea ...[Read More]
