Imaggeo on Mondays: Science above the Amazon rainforest

Imaggeo on Mondays: Science above the Amazon rainforest

The color and symmetry of the Amazon Tall Tower Observatory (ATTO) sticks out against the endless green of the rainforest. Built in a remote and pristine location, the ATTO tower is the tallest construction in South America. In a joint Brazilian-German project, atmospheric scientists aim to unravel the interaction of pristine rainforest with the atmosphere. With its height of 325 meters, the ATTO tower allows for studying atmospheric processes at different spatial scales.

Announcing the winners of the EGU Photo Competition 2019!

The selection committee received over 600 photos for this year’s EGU Photo Contest, covering fields across the geosciences. Participants at the 2019 General Assembly have been voting for their favourites throughout the week  of the conference and there are three clear winners. Congratulations to 2019’s fantastic photographers!

When I had the chance to view the Southern Hemisphere’s night sky with only the Antarctic Ocean in front of me, I realised how much we have already lost in the Northern Hemisphere and Europe. It almost seems as if the night is becoming extinct.

The Schwarzmooskogel-Höhlensystem is located in the Totes Gebirge in Austria and consists of 17 individual caves with a total length of about 140km. Inside, it felt like time did not pass or just passed really slowly. The shapes that the ice had sculptured were endless and took our breath away.

Due to the fast movement and the rough surface, there is not an established supraglacial or englacial meltwater system resulting in temporary ponds forming and subsequently draining during over several weeks to a few months.

Etna 2001 eruption, one of the most important of this volcano in the last century. This eruption marked a new cycle in the recent life of Etna and is also associated with flank instability threatening the lower inhabited eastern slope.

It is a pleasure to observe beautiful corners of the Earth, where people try to respect and cherish natural beauty.

Imaggeo on Mondays: Double strombolian explosions at Mt. Yasur volcano

Imaggeo on Mondays: Double strombolian explosions at Mt. Yasur volcano

The Yasur volcano located in Vanuatu archipelago is permanently active since its discovery in 1774 by Cpt. James Cook. Its activity consists mainly in moderate regular strombolian explosions within the crater. But sometimes, more powerful explosions throw ash and bombs beyond the crater rim and may represent a hazard for tourists and people living next to the volcano. Otherwise, the Mt Yasur displays regular fireworks, witness from the living Earth.
