Beyond EPICA Deep Drilling Campaign Begins in Antarctica

Published on December 01, 2022

The Little Dome C site in Antarctica has reopened for the second ice core drilling campaign of the international research project coordinated by the Institute of Polar Sciences of the CNR (National Research Council of Italy). By analysing the ice cores extracted from the deep ice in Antarctica, the project aims to obtain information dating back to 1.5 million years ago, regarding the evolution of temperature, the composition of the atmosphere, and the carbon cycle. The team includes 15 people and aims to start deep drilling to reach depths of a few hundred metres

Mountain ecosystems are complex, dynamic and exceptionally fragile. We are only beginning to understand the functional ecology of mountain ecosystems, but research already suggests that modifying communities of species will be detrimental to the environment, biodiversity and therefore an essential part of the support system for life on Earth. A new study, involving Ignacio Palomo, researcher at the institut des géosciences de l’environnement (IGE-OSUG, CNRS/UGA/IRD/Grenoble-INP-UGA), based (…)

Passing of Jérémie Mouginot

Published on September 30, 2022

It is with sadness that we learned of the death of Jérémie Mouginot on 28 September. Jérémie joined IGE in 2017. He was a brilliant and enthusiastic colleague, and a great friend to many of us. Committed to his research and the life of the laboratory, his departure leaves a huge gap.
Jérémie defended his PhD in 2008 at the Laboratoire de Planétologie de Grenoble on the processing and analysis of Mars Advanced Radar for Subsurface and Ionosphere Sounding data. He then joined the University (…)

Substantial contribution of iodine to Arctic ozone destruction

Published on September 20, 2022

Iodine chemistry plays a major role in controlling tropospheric ozone over the Arctic, according to a study published in the journal Nature Geosciences, carried out during the ship-based Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition.

Snow and ice re-emissions control Arctic atmospheric mercury concentrations during summer

Published on September 06, 2022

Mercury is a toxic contaminant that impacts human, ecosystems and wildlife health globally and is a pressing concern in the Arctic due to the high concentrations found there.
However, there are very few mercury sources located in the Arctic and virtually all toxic mercury originates from outside the region. Elemental mercury (Hg0) is relatively inert (chemically inactive) and long lived and is found in air and the ocean that can be transported long distances, which can take days, months or (…)

“Climate Change for kids” article collection

Published on August 31, 2022

A large effort of communication has been conducted around the release of the latest IPCC assessment report. One project, initiated by Chris Jones (lead author of Chapter 4 of Working Group I on “Future global climate”), and Sophie Berger and Robin Matthews (Technical Support Unit for Working Group I), was to explain the basic concepts related to climate and climate change to children. They invited fellow IPCC lead authors and early career researchers interested in science communication to (…)

Halving of Swiss glaciers volume since 1931

Published on August 23, 2022

Researchers at ETH Zurich and Université Grenoble Alpes have reconstructed the extent of Switzerland’s 20th century glacier ice loss for the first time. For this purpose, the researchers used historical imagery and conclude that the country’s glaciers lost half their volume between 1931 and 2016.

Major glacier in northern Greenland shows dramatic signs of weakening

Published on August 08, 2022

An international collaboration of researchers from Europe and the United States have detected a dramatic retreat of a major glacier in North Greenland, long considered stable.

A novel view on the key factors controlling the long term response of the Greenland Ice-Sheet flow to surface melt water

Published on August 02, 2022

Ice flowing from the interior to the lower elevated edges of Greenland exerts a key control on how much the Ice-Sheet will lose mass as temperatures rise. The faster the ice flows, the faster it reaches the edges where it can be discharged in the ocean or melt. Predicting ice flow, however, is a challenging task. In Greenland, ice flow is mainly controlled by the sliding of ice over its underlying bedrock and the modulation of it by surface melt water supplied to the base through vertical (…)
