Imaggeo on Mondays: Watching the world from space with EarthKAM

This photo was taken from the International Space Station (ISS), approx. 400 km above the Earth, in the NASA-led educational project Sally Ride EarthKAM (www.earthkam.org), Mission 58, April 2017. The image was requested by a team of 10th and 11th grade students from the National College of Computer Science, Piatra-Neamț, Romania, coordinated by me. The …[Read More]

Imaggeo on Mondays: Small scale processes, large scale landforms

This picture was taken in a sea cliff gully landscape at the Portuguese coast. It shows the microrelief which small scale wash and erosional processes produce in these poorly consolidated sediments. These small scale landforms could be interpreted as initial stages of larger scale gully landforms, which can be seen in the back. This highlights …[Read More]

Imaggeo on Mondays: Hole in a hole in a hole…

This photo, captured by drone about 80 metres above the ground, shows a nested sinkhole system in the Dead Sea. Such systems typically take form in karst areas, landscapes where soluble rock, such as limestone, dolomite or gypsum, are sculpted and perforated by dissolution and erosion. Over time, these deteriorating processes can cause the surface …[Read More]

Ancient sand dunes exposed off a cliff face on the shoreline of Nova Scotia at the Islands Provincial Park. The juxtaposition of the high angled strata and flat lying layers above revels the drastic change in climate in Nova Scotia’s history; from vast sand dunes to a calm lake system, and presently the western coastline …[Read More]

The badlands valley of Civita di Bagnoregio is a hidden natural gem in the province of Viterbo, Italy, just 100 kilometres from Rome. Pictured here is the ‘wall,’ one of the valley’s most peculiar features, where you can even find the wooden structural remains of a trail used for agricultural purposes in the 19th and …[Read More]

Imaggeo on Mondays: The Gower Peninsula, a coast marked by time

The Gower Peninsula in South Wales, United Kingdom, is a spectacular site to view a sunset. However, to geologists, the shore is also a prime spot to find artifacts from Earth’s ancient and recent past. “The limestone coastline is dotted with caves that are rich in Quaternary flora and fauna,” said Mike Smith a visiting …[Read More]
