Geosciences Column: The quest for life on Mars

Geosciences Column: The quest for life on Mars

Understanding where we come from and whether Earth is the only habitable planet in the Solar System has been a long standing conundrum in science. Partly because it is our nearest neighbour, partly because of its past and current similarities with our own home, Mars, the red planet, is a likely contender in the quest for extra-terrestrial life. In this guest blog post, James Lewis, a PhD student a ...[Read More]

Landslides, lake tsunamis and the tragedy of Lago Cabrera

Fifty years ago, on 19th February 1965, a rock and ice landslide fell from the summit face of Volcan Yate in southern Chile. It was mid-summer, and was one of the warmest and wettest February records in that part of Chile on record. The debris slid rapidly down a narrow gully, losing at least 1500 metres in elevation, until it emerged into the southern end of a small montane lake. This triggered a ...[Read More]

Our EGU session died, what went wrong?

Have you ever had this experience? You develop a session which you think could be such a great platform or a subject that definitely interests a lot of people and then only a few people register…this happened to Jan, me, and several others this year and our proposed sessions (GM1.2 Emerging research fields in geomorphology and GM 1.4 Data wealth versus data poverty – new strategies for geomo ...[Read More]

Soils at Imaggeo: Gypsum concretions in a soil horizon

Antonio Jordán, University of Seville, Sevilla, Spain Most Gypsisols are formed when gypsum (calcium sulfate) from gypsiferous parent materials is dissolved and moves through soil water, precipitating in an accumulation soil horizons. Triassic rock outcrops in almost all Andalusia consist mainly of red and variegated clays and in some cases by clays of different colors are known as the iridescent ...[Read More]

Imaggeo on Mondays: A Patagonia landscape dominated by volcanoes

Imaggeo on Mondays: A Patagonia landscape dominated by volcanoes

Imagine a torrent of hot and cold water, laden with rock fragments, ash and other debris hurtling down a river valley: this is a lahar. A by-product of eruptions of tall, steep-sided stratovolcanoes, lahars, are often triggered by the quick melting of snow caps and glaciers atop high volcanic peaks. The history of the Ibañes River and its valley, in southern Chile, are dominated by their proximity ...[Read More]

Monday paper: Thermal shock and splash effects on burned gypseous soils from the Ebro Basin (NE Spain)

León J, Seeger M, Badía D, Peters P, Echevarría T: Thermal shock and splash effects on burned gypseous soils from the Ebro Basin (NE Spain). Solid Earth, 5, 131-140. DOI: 10.5194/se-5-131-2014. Abstract Fire is a natural factor of landscape evolution in Mediterranean ecosystems. The middle Ebro Valley has extreme aridity, which results in a low plant cover and high soil erodibility, especially on ...[Read More]

Four years in Tibet – Eva Huintjes

Four years in Tibet – Eva Huintjes

The Tibetan Plateau – area: 2.5 million km2, mean elevation: 4,700 m a.s.l., surrounded by a series of high mountain ranges that are home to some of the world’s highest peaks: Himalayas, Karakoram, Pamir, Kunlun Shan. Considering these characteristics and the unique cultural heritage of Tibet the decision was easy when I was asked if I am interested working in a project on the regional patterns of ...[Read More]
