Imaggeo On Monday: the EGU Photo Competition – ONE WEEK LEFT!

In 2010 EGU held our first annual Photo Competition at the General Assembly in Vienna. Since then hundreds of photos have been shared on imaggeo by geoscientists and researchers just like you, with a lucky few being selected each year to be highlighted during the meeting and voted on by our members.   These images can be of anything to do with geology or geoscience – we get many beautif ...[Read More]

Imaggeo On Monday: Fingerprint in the cotton

Imaggeo On Monday: Fingerprint in the cotton

This photo is taken at the Pamukkale (meaning “cotton castle” in Turkish), a natural site near Denizli, Turkey. This location is world famous for terraces made of snow-white travertine, a sedimentary rock deposited by water from the hot springs, and a stunning turquoise water color. Close look at the surface texture reveals an extraordinary pattern created by the thermal water slowly f ...[Read More]

Imaggeo On Monday: Wannabe cubic calcite

Imaggeo On Monday: Wannabe cubic calcite

This imperfect cube of calcite was formed on the gold surface during the electrochemically assisted scaling process. Once negative electrochemical potential is applied to the gold surface, the oxygen dissolved in water undergoes reduction, yielding hydroxide anions. These anions accumulate at the gold-solution interface, forming a high pH layer. As calcite becomes less soluble with the increasing ...[Read More]

Imaggeo On Monday: Blue cements in Jurassic rocks?

Staining of thin sections and rock slabs is a method of identification that has long helped researchers to distinguish certain minerals which often otherwise appeared very similar. Modern studies have now largely replaced this method of identification with more analytical techniques that usually provide a higher degree of certainty, such as analysis with a microprobe or Scanning Electron Microscop ...[Read More]

Imaggeo On Monday: One with the Cosmos

Imaggeo On Monday: One with the Cosmos

Camping under the stars is an experience that allows people to connect with the cosmos in a unique and profound way. As they set up their tents and gaze up at the night sky, they are reminded of the vastness and beauty of the universe. They can see the stars, the planets and other celestial objects, and feel a sense of awe and wonder. They are reminded that they are just a small part of something ...[Read More]

Imaggeo On Monday: Pantone of Blue Mountains, light scattering.

Imaggeo On Monday: Pantone of Blue Mountains, light scattering.

The light’s interaction with matter enables scientists to observe greenhouse gases from space, but also creates the shifting blue tones throughout the mountains that hikers travel long distances to admire! The blue shades are created by an effect called Raleigh scattering, where very small atmospheric particles between the viewer (or camera) and the mountains cause the shorter wavelength lig ...[Read More]

Imaggeo On Monday: Blood moon over Germany

Imaggeo On Monday: Blood moon over Germany

A blood moon occurs during a total lunar eclipse. The sunlight falling through the air layers of the Earth’s atmosphere is refracted inwards, whereby especially the short-wave blue components are weakened by scattering. The long-wave red components, on the other hand, still reach the moon, which leads to the red colouring.   Photo by Simon Fuhrmann shared on imaggeo.egu.eu.   Imagg ...[Read More]

Imaggeo On Monday: Aurora show on the road

Imaggeo On Monday: Aurora show on the road

In Sweden a beautiful Northern Lights show proceeds unnoticed by the busy drivers passing by. The Northern Lights or Aurora Borealis are spectacular lights created as a result of disturbances in the Earth’s magnetosphere caused by solar winds. They are visible at both polar regions and or often seen as veils or lines of greenish-blue light. Photo by Junbin Zhao shared on imaggeo.egu.eu. &nbs ...[Read More]
