I am a petrographer at the University of Padova, Italy, studying the metamorphic rocks that form the deep Earth’s crust beneath our feet, and what happens when they get so hot to start to melt. I’ve spent (enjoyed I should say) more than 30 years looking at rocks with an optical microscope. This simple, cheap tool, and more importantly, its skilled use, remain key ingredients for good research in ...[Read More]

Iceland’s rootless volcanoes

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? Is it perched above a chasm of subterranean molten rock?

However, with a little insider knowledge from those who’ve attended the General Assembly many times before, it is possible to have a (scientifically) rewarding week in Vienna, without breaking the bank. Before you get there A sure way to save a fe ...[Read More]

This was taken during a study, undertaken by me and my colleagues, on the sea ice of McMurdo Sound, Antarctica. We designed the project to document how supercooled water carrying suspended ice crystals flows along its pathway towards the open ocean. Ultimately, this work aims to assess the Ross Ice Shelf’s contribution of local melt to the long-term trend of increased sea ice cover around Antarcti ...[Read More]
