Imaggeo on Mondays: The ephemeral salt crystals

Imaggeo on Mondays: The ephemeral salt crystals

Rock salt stalactites (Speleothems) are the indicators of entrance in a salt cave. These crystal stalactites precipitate from brine only at the entrance in the salt caves, as that is the only place where the physical and chemical properties of the air and the brine dripping from the ceiling allow these crystals to grow and …[Read More]

Imaggeo on Mondays: Monitoring Antarctica’s ocean current

This week’s featured image depicts a quiet and still oceanic landscape in Antarctica, but polar scientists are studying how energetic and variable the ocean currents in this part of the world can be. In this picture, the marine research vessel RRS James Clark Ross is making its way through the Lemaire Channel, a small passage …[Read More]

This picture was taken in the Arctic in May 2018. It shows the unmanned marine vehicle Proteus in front of the tidewater glacier Conwaybreen in the Kongsfjorden in Spitsbergen in the Svalbard Archipelago. The front of tidewater glaciers is an almost vertical wall of ice standing over the sea where direct measurements are very critical …[Read More]

Imaggeo on Mondays: Foggy Bandon beach, Oregon

This picture was taken at Bandon beach, Oregon. Bandon is well-known for its memorable seascape of stacks of all shapes and sizes. These rock formations are known to geologists as ‘knockers’ and carry nicknames like ‘the Wizards hat’. They date from the Jurassic period – about 200 to 145 million years ago – and are …[Read More]

Imaggeo on Mondays: Our QUEST for innovative tools to understand changing environments and climates

The photo shown here shows typical sampling work underground. You can see Ola Kwiecien and Cinthya Nava Fernandez, researchers at Ruhr University Bochum in Germany, collecting dripwater in New Zealand’s Waipuna Cave as part of a four-year EU-funded monitoring programme. Our research aims at developing innovative geochemical indicators that we can use to quantify changes …[Read More]
