Galileo Galilei, after whom the conferences are named

EGU Galileo Conference programme: call for proposals

  • EGU news
  • 27 November 2019

The EGU is now accepting proposals for Galileo Conferences, which aim to address well-focused cutting-edge topics at the frontier of geosciences research. The conferences are informal: the state-of-the-art is outlined in keynote talks designed to trigger in-depth discussion of important aspects of the conference topic. EGU members can propose to organise a Galileo Conference and apply for funding by 29 February 2020.

Large-scale particulate air pollution and chemical fingerprint of volcanic sulfate aerosols from the 2014–2015 Holuhraun flood lava eruption of Bárðarbunga volcano (Iceland)

This study, benefiting especially from recently developed mass spectrometry observations of aerosols, highlights unknown properties of volcanic sulfates in the troposphere. It shows their specific chemical fingerprint, distinct from those of freshly emitted industrial sulfates and background aerosols. We also demonstrate the large-scale persistence of the volcanic sulfate pollution over weeks. Hence, these results cast light on the impact of tropospheric eruptions on air quality and climate.

Low-temperature triple-capillary cryostat for ice crystal growth studies

We have built a triple-capillary cryostat designed to reduce potential instrumental effects that may have influenced earlier measurements and to improve our understanding of the processes responsible for ice crystal shapes and sizes. In this cryostat, a crystal forms on one of three well-separated and ultrafine capillaries. In this paper we describe the new instrument and present several observations made using the instrument to illustrate the instrument’s advantages.

Compacting the description of a time-dependent multivariable system and its multivariable driver by reducing the state vectors to aggregate scalars: the Earth’s solar-wind-driven magnetosphere

A methodology is developed to simplify the mathematical description of activity in a time-dependent driven system. The method describes the response in the system that is most-closely related to the driver. This reduced description has advantages: low noise, high prediction efficiency, linearity in the described system response to the driver, and compactness. The analysis of the Earth’s magnetospheric system is demonstrated.

Distinct stores and the routing of water in the deep critical zone of a snow-dominated volcanic catchment

This paper examines the influence of the subsurface structure on water routing, water residence times, and the hydrologic response of distinct groundwater stores and further investigates their contribution to streamflow. We conclude that deep groundwater from the fractured aquifer system, rather than shallow groundwater, is the dominant source of streamflow, which highlights the need to better characterize the deep subsurface of mountain systems using interdisciplinary studies such as this one.

Setting trees aflame to understand the carbon balance of fires

Setting trees aflame to understand the carbon balance of fires

Smoke clears after an experimental wildfire in Australian eucalyptus forest carried out for carbon balance estimations of wildfires. We meticulously measured the carbon in all leaves, twigs, logs and bark in a forest block about 35km east of Manjimup and then they set it on fire with help from the Dept. of Parks and Wildlife, [Western Australia]. We the counted the carbon all over again including measuring ash and charcoal and calculating what percentage of the original carbon gets locked …

#EGU2020 Sessions in the Spotlight: Hotspots, LIPs and LLSVPs: a global investigation with joint constraints from geochemistry, seismology and geodynamics

The Earth Sciences are so broad, that sometimes we can end up forgetting the other parts of it exist. We can get so focused on our field that we forget there might be other people working on really similar things, who might have something really useful to say. The EGU conference is great for solving this problem – it’s big enough to bring together all sorts of Earth scientists, but still small enough that you can have a chat without …

Cryo Adventures – What’s currently going on in Antarctic science?

Cryo Adventures – What’s currently going on in Antarctic science?

As Christmas gets closer, days are getting shorter in the northern hemisphere. A good excuse to get cosy inside on the sofa, drinking tea and eating Christmas biscuits. Meanwhile, a few thousand of scientists are heading “South”, to Antarctica, where the lengthening days provide the perfect conditions to conduct a whole variety of scientific field expeditions… Science in Antarctica Just last week, we celebrated Antarctica Day, 60 years after the signing of the Antarctic Treaty, which set aside Antarctica as …
