Imaggeo on Mondays: Sunset over the Labrador Sea

Ruby skies and calm waters are the backdrop for this week’s Imaggeo image – one of the ten finalist images in this year’s EGU Photo contest. “I took the picture while on a scientific cruise in West Greenland in 2013,” explains Christof Pearce, a postdoctoral researcher at Stockholm University. “We spent most of the time inside the fjord systems around the Greenland capital, Nuuk, but this specific ...[Read More]

Imaggeo on Mondays: Escullos

This picture shows a Quaternary aeolianite fossil dune at the Escullos beach, in the Nature Reserve of Cabo de Gata (Almeria, Spain). Originally a soft accumulation of sand grains, shaped by the wind into large mounds and ridges, the dunes eventually turn into rock. As the sediments compact under their own pressure and expel any moisture and fluids retained within them, they become lithified and b ...[Read More]

Imaggeo on Mondays: Painted Hills after the storm.

The geological record preserved at John Day Fossil beds, in Oregon, USA, is very special. Rarely can you study a continuous succession through changing climates quite like you can at this National Park in the USA. It is a treasure trove of some 60,000 plant and animal fossil specimens that were preserved over a period of 40 million years during the Cenozoic era (which began 66 million years ago). ...[Read More]

The known unknowns: Climate, Life, and the Solid Earth (Part V)

After four fascinating instalments in the known unknowns series we have (sadly) come to the final post. Since the series began in September we have explored the top questions that still remain unanswered when it comes to understanding the inner workings of the planet as well as how the interplay of a number of systems that occur at the Earth’s surface give rise to its varied landscapes. The series ...[Read More]
