Imaggeo on Mondays: A voyage through scales – The Badlands National Park, South Dakota.

Layer upon layer of sand, clay and silt, cemented together over time to form the sedimentary units of the Badlands National Park in South Dakota, USA. The sediments, delivered by rivers and streams that criss-crossed the landscape, accumulated over a period of millions of years, ranging from the late Cretaceous Period (67 to 75 million years ago) throughout to the Oligocene Epoch (26 to 34 million ...[Read More]

Geosciences Column: Recent and future changes in the Greenland Ice Sheet

Laura Roberts-Artal June 5, 2015

Over the past few decades, the Arctic region has warmed more than any other on Earth. The Greenland Ice Sheet is losing mass faster than ever before, and is expected to keep melting with consequences for global sea-level rise and ocean circulation. At a media briefing, during the EGU’s General Assembly in April (stream it here), researchers presented new results on the factors that influence the G ...[Read More]

GeoEd: I’m a Geoscientist 2015

Laura Roberts-Artal May 29, 2015

Imagine a talent show where contestants get voted off depending on their skills in their area of choice. Then imagine that this talent show is populated by geoscientists with school students voting them off based on the scientist’s ability to communicate their research well. This is the basis of an educational initiative called I’m a Geoscientist, a spinoff of UK’s I’m a Scientist. I’m a Geoscient ...[Read More]

Imaggeo on Mondays: A fold belt within a grain

Laura Roberts-Artal May 25, 2015

Tiny crinkly folds form the main basis of today’s Imaggeo on Mondays. Folding can occur on a number of scales; studying folds at all scales can reveal critical information about how rocks behave when they are squeeze and pinched, as described by Sina Marti, from the University of Basel. Although many geoscientists have seen such fold structures many times before, if you noticed the scale bar in th ...[Read More]

GeoEd: Why So Serious?

Laura Roberts-Artal May 22, 2015

In this edition of GeoEd, Sam Illingworth, a lecturer in science communication at Manchester Metropolitan University, explores the benefits of a more informal teaching style and how the incorporation of play into everyday teaching can help to engage and enthuse students who oterhwise struggle to connect with the sciences. Despite the hard work, there are some real perks to being a scientists: fiel ...[Read More]
