I’ve taken many photos on fieldwork, everywhere from Malaysia to Antarctica but this particular photo was taken in my ‘home’ lab at the University of East Anglia (UEA) in Norwich, UK. Atmospheric scientists collect air samples canisters such as these from around the world: from high altitude research aircraft (such as the Geophysica), long-term measurement time series (such as Ca ...[Read More]

Over the last few decades, Antarctic ice shelves have been disintegrating at a rapid rate, likely due to warming atmospheric and ocean temperatures, according to scientists. New research reveals that one type of threat to ice shelf stability might be more widespread that previously thought. A study recently published in EGU’s open access journal The Cryosphere identified several regions in Antarct ...[Read More]

Pictured here is a snapshot of an environment in transition. Today’s featured photo was taken at the foot of Monte Fitz Roy, a jagged Patagonia mountain located in Los Glaciares National Park on the border between Argentina and Chile. The Patagonia region in South America is the second biggest source of glaciers in the southern hemisphere, behind Antarctica, but the region is losing ice at a rapid ...[Read More]

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]
