EGU 2019 call for sessions

  • EGU news
  • 25 June 2018

The call for session proposals for the EGU 2019 General Assembly is now open. Until 6 September you can suggest new sessions with conveners and description, or you can propose modifications to current ones. Please note that, similarly to last year, the 6 September deadline also applies to short courses and townhall meetings. The deadline to submit proposals for Union Symposia and Great Debates is 15 August. The next EGU General Assembly is taking place in Vienna, Austria on 7–12 April 2019.

Ionospheric and thermospheric response to the 27–28 February 2014 geomagnetic storm over north Africa

The novelty of this paper lies in the fact that it addresses the thermosphere–ionosphere coupling in a midlatitude site in north Africa. We have used Fabry–Perot measurements of thermospheric winds and wide-angle camera detection of ionospheric structures at an altitude of about 250 km. We have also used GPS data to extract the TEC over the studied area. We have focused our study on the 27 February geomagnetic storm.

On the role of the North Equatorial Counter Current during a strong El Niño

Results from a high-resolution ocean model show that during the strong El Niños of 1983 and 1998, transport of warm water in the equatorial Pacific was dominated by the North Equatorial Counter Current and not by equatorial Kelvin waves. The results show why the NECC fails to do this in most years and how stronger than normal annual Rossby waves near the Equator can both trigger the El Niño in the western Pacific and help to ensure that the warm water arrives off South America around Christmas.

On the dynamic nature of hydrological similarity

In this study we explore the role of spatially distributed information on hydrological modeling. For that, we develop and test an approach which draws upon information theory and thermodynamic reasoning. We show that the proposed set of methods provide a powerful framework for understanding and diagnosing how and when process organization and functional similarity of hydrological systems emerge in time and, hence, when which landscape characteristic is important in a model application.

Geosciences Column: The best spots to hunt for ancient ice cores

Where in the world can you find some of Earth’s oldest ice? That is the question a team of French and US scientists aimed to answer. They recently identified spots in East Antarctica that likely have the right conditions to harbor ice that formed 1.5 million years ago. Scientists hope that obtaining and analysing an undisturbed sample of ice this old will give them clues about Earth’s ancient climate. The team published their findings in The Cryosphere, an open access …

Image of the Week – Making waves: assessing supraglacial water storage for debris-covered glaciers

A creeping flux of ice descends Everest, creating the dynamic environment of Khumbu Glacier. Ice and snow tumble, debris slumps, ice cliffs melt, englacial cavities collapse, ponds form and drain, all responding to a variable energy balance. Indeed, Khumbu Glacier is a debris-covered glacier, meaning it features a layer of sediment, rocks and house-sized boulders that covers the ice beneath. Recent advances in understanding debris-covered glacier hydrology come from combining in situ surveys with remotely sensed satellite data. Khumbu Glacier …

Event Report: UN Science, Technology and Innovation Forum 2018

Last month GfGD Director, Dr Joel Gill, attended the UN Annual Forum on Science, Technology and Innovation for the Sustainable Development Goals (SDGs). With few other, if any, geoscience organisations in attendance we believed it to be important for Geology for Global Development to engage and ensure a voice for geoscience at this significant event. Event Overview UN General Assembly resolution 70/1 on the 2030 Agenda for Sustainable Development calls for an annual science, technology and innovation (STI) Forum to …
