On the desolate Antarctic peninsula, a colony of penguins creates a hub of biodiversity. One may ask, how exactly do those aquatic birds help maintain and enrich the variety of different kinds of organisms from plants and animals, to a wide range of insects and micro-organisms that live on our planet? The answer is quite intriguing. Scientists from the University of Science and Technology of China ...[Read More]

The EGU General Assembly provides ground for formal presentations and sessions conveying a body of knowledge. However, science is so much more. It is a social process driven by shared values, such as openness and integrity, and established customs, like peer review. As such, working in science is inherently a collaborative effort, and the EGU supports that by giving participants plenty of opportun ...[Read More]

Tidal channel and saltmarsh in Germany

“A tidal channel (‘Priel’) in a saltmarsh of the Wadden Sea, northern Germany.” Tidal channels are an integral part of salt marshes and form naturally, connecting the marsh with the nearest water body. These tidal channels provide an ecological bounty for a diverse range of life, from plants to invertebrates to birds and mammals – and include many benefits for the peo ...[Read More]

Imaggeo On Monday: Elegance with no functionality

The Montejaque dam, with its 84 meters of height, is one of the first vaulted dams built in Europe. Currently, it remains only as a vestige of one of the major hydroelectric projects by the “Sevillana de Electricidad” company. Preliminary studies for its construction began in 1917. Some of these studies indicated that the project was unfeasible due to the karstic nature of the terrain, ...[Read More]

Imaggeo On Monday: Layers of dust and snow

This image shows layers of dust and snow at the surface of Fox Glacier, Southern Alps, New Zealand. The glacier surface in the upper part of Fox Glacier’s ice fall is heavily crevassed and intersected into seracs. Individual layers of fresh and old snow are visible, some with visible thin dust layers at their surface. The more reddish dust layers in the lower part of the image had been gener ...[Read More]

Imaggeo On Monday: Iceberg A-81, Brunt Ice Shelf, Antarctica

Information from a British Antarctic Survey Press Release. A huge iceberg (1550 km²), almost the size of Greater London, has broken off the 150m thick Brunt Ice Shelf. It calved after cracks that have been developing naturally over the last few years extended across the entire ice shelf, causing the new iceberg to break free. This occurred on Sunday 22 January between 19.00 and 20.00 UTC during a ...[Read More]
