The geothermal area Sol de Mañana is part of the Altiplano–Puna volcanic complex shared between Bolivia and Chile. The area is characterized by volcanic activity and the sulphur springs host mud lakes and steam pools. The different colours stem from thermophilic, hyperthermophilic and acidophilic bacteria that colonize areas of varying temperatures. Description by Julia Miloczki, after the ...[Read More]

Minerals and Art: a centuries-old connection
Since ancient times, colours have been fundamental for artistic expression: pigments have always been created from fruits, leaves-flowers, and minerals. During the centuries, new material discoveries and techniques increased the shades we can still see and use nowadays. Once upon a Prehistoric time… El Castillo Cave, in Spain, is one of the earliest known cave paintings, dated to more than 40,000 ...[Read More]

Camp Century re-visited: sediment from the bottom of a Cold War ice core reveals Greenland’s warm past
A Cold War nuclear-powered military base inside the Greenland Ice Sheet sounds like science fiction, but the science that came out of this U.S. army installation was anything but fiction. In last week’s EGU CR blog post, Paul Bierman and Amanda Schmidt discussed the advances made by the U.S. military in operating across the Greenland Ice Sheet that culminated in the establishment of Camp Century i ...[Read More]

The toxic and wondrous world of academia with Science Sisters
Good morning, dear readers, this is your editor-in-chief speaking. We are currently experiencing some difficulties in academia, but we ask you to stay calm and remain in your seats with the seatbelt fastened. In the event of loss of pressure, make sure to publish your own paper first (to increase the pressure on your peers). Yes, it’s me! Your favourite (and only) editor-in-chief! And because runn ...[Read More]

Geodesists on Tour: On the left side of the road for getting the g
Getting the small g (the absolute gravity value) outdoors has always been some sort of a challenge. But, in the early 2000s the possibility to measure gravity has changed by the arrival of the first A10 absolute gravimeters. They to a large extent revolutionized the approach of performing gravity measurements in the open field and with that improved the approach to design and measure national grav ...[Read More]
