EGU flags outisde the Austria Center Vienna during the EGU General Assembly

EGU General Assembly 2020 Media Advisory 1 – Media registration now open

  • Press release
  • 18 December 2019

The 2020 General Assembly of the European Geosciences Union (EGU) provides an opportunity for journalists to find out about the latest research in the Earth, planetary and space sciences and to talk to researchers from all over the world. The meeting, the largest geosciences conference in Europe, is anticipated to bring together more than 15,000 scientists. It runs from 3 to 8 May at the Austria Center Vienna, in Vienna, Austria.

One-third of recent global methane increase comes from tropical Africa

  • Press release
  • 11 December 2019

Concentrations of methane, a greenhouse gas about 28 times more potent than carbon dioxide, have risen steadily in Earth’s atmosphere since 2007. Although several potential explanations, including an increase in methane emissions from the tropics, could account for this upsurge, due to a lack of regional data scientists have been unable to pinpoint the source. Now a study published in the European Geosciences Union (EGU) journal Atmospheric Chemistry and Physics uses satellite data to determine that one-third of the global increase originates in Africa’s tropics.

A decade of variability on Jakobshavn Isbræ: ocean temperatures pace speedthrough influence on mélange rigidity

Jakobshavn Isbræ, considered to be Greenland’s fastest glacier, has varied its speed and thinned dramatically since the 1990s. Here we examine the glacier’s behaviour over the last decade to better understand this behaviour. We find that when the floating ice (mélange) in front of the glacier freezes in place during the winter, it can control the glacier’s speed and thinning rate. A recently colder ocean has strengthened this mélange, allowing the glacier to recoup some of its previous losses.

Electron spin resonance (ESR) thermochronometry of the Hida range of the Japanese Alps: validation and future potential

Rates of landscape evolution over the past million years are difficult to quantify. This study develops a technique which is able to measure changes in rock cooling rates (related to landscape evolution) over this timescale. The technique is based on the electron spin resonance dating of quartz minerals. Measurement protocols and new numerical models are proposed that describe these data, allowing for their translation into rock cooling rates.

Altitude profiles of cloud condensation nuclei characteristics across the Indo-Gangetic Plainprior to the onset of the Indian summer monsoon

Concurrent measurements of the altitude profiles of the concentration of cloud condensation nuclei (CCNs), as a function of supersaturation (ranging from 0.2 % to 1.0 %), and aerosol optical properties were carried out aboard an instrumented aircraft across the Indo-Gangetic Plain (IGP) just prior to the onset of the 2016 Indian summer monsoon (ISM). A high CCN concentration is observed up to 2.5 km across the IGP, indicating the significant possibility of aerosol indirect effects.

Why did deep convection persist over four consecutive winters (2015–2018) southeast of Cape Farewell?

The region south of Cape Farewell (SCF) is recognized as a deep convection site. Convection deeper than 1300 m occurred SCF in 2015 and persisted during three additional winters. Extreme air–sea buoyancy fluxes caused the 2015 event. For the following winters, air–sea fluxes were close to the climatological average, but local cooling above 800 m and the advection below 1200 m of a fresh anomaly from the Labrador Sea decreased stratification and allowed for the persistence of deep convection.

The multitasking skillbox of researchers, direct experiences from Early Career Scientists.

Science is “the study of the nature and behaviour of natural things and the knowledge that we obtain about them” (Collins online dictionary). In other words, science is tightly linked to gaining knowledge. However, this definition and many others never mention that to gain knowledge through science, a vast amount of experience must be acquired beforehand and put into practice every day by scientists. Today, our post will give our blog readership the chance to read some stories behind the …

Imaggeo On Mondays: Contrasted island in the Mozambic Canal

Mayotte, the so-called “perfume island”, is a volcanic island of the Comoros Archipelago and a French overseas department which hit the headlines in 2018-2019 with an enigmatic as well as frightening seismic swarm, recently linked to the appearance of a new submarine volcano nearby. Surrounded by one of the largest lagoons in the World and sprinkled with small islands, Mayotte only reaches 374 km2 above sea level for its 256000 inhabitants. This population is still increasing, leading to an anarchic …
