Meteorite impact turns silica into stishovite in a billionth of a second

The Barringer meteor crater is an iconic Arizona landmark, more than 1km wide and 170 metres deep, left behind by a massive 300,000 tonne meteorite that hit Earth 50,000 years ago with a force equivalent to a ten megaton nuclear bomb. The forces unleashed by such an impact are hard to comprehend, but a team of Stanford scientists has recreated the conditions experienced during the first billionths ...[Read More]

An Andy Warhol Moment for Liverpool’s Geomagnetism Group – dating the formation of the Earth’s Inner core

This week, my PhD supervisor, Andy Biggin, had a paper out in Nature. The findings of this new research point towards the Earth’s inner core being older than we’d previously thought. Recent estimates, suggest that the Earth’s solid inner core started forming between half a billion and one billion years ago. However, Andy’s (and co-workers) new measurements of ancient rocks as the ...[Read More]

Image of the Week: Antarctic ice-shelf thickness

Thickness of floating ice shelves in Antarctica. Ice thickness is greatest close to the grounding line where it can reach 1000 meters or more (red). Away from the grounding line, the ice rapidly thins to reach a few hundreds of meters at the calving front. Ice thickness varies greatly from one ice shelf to another. Within ice shelves, “streams of ice” can be spotted originating from in ...[Read More]

Riding the Storm: The Arctic Circle Traverse 2015

In the morning on the 19th of May, we – the Arctic Circle Traverse 2015 – found ourselves in a great dilemma; to stay or to go? On our check-in conversation with the KISS crew, we were informed that an east front from Kulusuk was expected to hit our location up on the ice sheet sometime in the afternoon. The relatively low winds that we were experiencing would get stronger, and the visibility woul ...[Read More]

Geology Photo of the Week #48

This edition of the photo of the approximate week (plus or minus 1 – sorry for my tardiness) is very cool in that it shows when earth processes that are invisible suddenly become very visible. In this case the submarine volcano, El Hierro, is erupting and instead of the usual bursting lava and fireworks display the only evidence of the turmoil going on is this discolouration at the oceanR ...[Read More]
