Imaggeo on Mondays: Breath from the underground

Imaggeo on Mondays: Breath from the underground

The heat seeping from the geothermal area which is part of the Krafla volcanic system in Iceland, ‘powers’ the steaming vent at Hverir (Hverarönd). The area is well known for its mud pots and sulphuric gas fumaroles, complete with pungent eggy smell. Some of the vents are in fact boreholes drilled in the 50’s for …[Read More]

Imaggeo on Mondays: Erebus Ice Tongue Cave

Imaggeo on Mondays: Erebus Ice Tongue Cave

The interior of this ice cave at the Erebus glacier tongue is cathedral-like. Imagine standing in the cold interior, icy blue stalactites dangling from the cave roof; the sense of awe is overwhelming. Mt. Erbus is the world’s southernmost active volcano on Ross Island, in Antarctica. Winding its way down its lower slopes is Erebus …[Read More]

Imaggeo on Mondays: Natural Bridges Monument, Utah, USA

Slowly but surely, the force of water has carved out a beautiful landscape in the sandstones of the Colorado Plateau. Suspended over canyons, naturally formed bridges and arches are the starts of Utah’s first national monument. The geological and modern  history of the region is rich as Kimberly Galvez, a student of the University of …[Read More]

“You can never step into the same river, for new waters are always flowing on to you.” —Heraclitus of Ephesus Rushing rivers, with their unremitting twists and turns and continuous renewal, are often used as a metaphor for life, but the analogy is just as appropriate for scientific research, I reflected as I walked along …[Read More]

Imaggeo on Mondays: Polar backbone (Arctic Ocean)

This image was taken during the Arctic Ocean 2016(AO16) expedition that ventured to the central regions of the Arctic Ocean, including the North Pole. It shows a pressure ridge, or ice ridge, as viewed from onboard the deck of the icebreaker Oden. It was quite striking that the ice ridge resembled an image of a …[Read More]

Imaggeo on Mondays: Sneaking up from above

Imaggeo on Mondays: Sneaking up from above

Take some ice, mix in some rock, snow and maybe a little mud and the result is a rock glacier. Unlike ice glaciers (the ones we are most familiar with), rock glaciers have very little ice at the surface. Looking at today’s featured image, you’d be forgiven for thinking the Morenas Coloradas rock glacier wasn’t …[Read More]
