The light’s interaction with matter enables scientists to observe greenhouse gases from space, but also creates the shifting blue tones throughout the mountains that hikers travel long distances to admire! The blue shades are created by an effect called Raleigh scattering, where very small atmospheric particles between the viewer (or camera) and the mountains cause …[Read More]
COVID-19 has been a disruptive ‘tsunami’ that most countries were not prepared to handle. The pandemic has been representing a global slow-onset long-lasting disaster that has drastically challenged all emergency management systems worldwide. The pandemic slow-onset disaster has been characterized by a prolonged emergency phase with varying intensity levels, and a cyclic behavior, where the …[Read More]
This week we interview Géraldine Zenhäusern, a PhD student at ETH Zurich’s Department of Earth Sciences, about her experience of being on the frontline of spotting Marsquakes with NASA’s InSight mission…. What is the InSight mission? The NASA InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission is a geophysical observatory (see Fig. …[Read More]
Hi, this is your ST-ECS team. We are a group of Early Career Scientists (ECSs) of the Solar-Terrestrial (ST) division, and we enjoy organizing events and activities with and for ST-ECS, both during the EGU General Assembly and throughout the year. Our aim is to increase the visibility of ECSs and provide you with opportunities …[Read More]
If you are registered for the EGU23 General Assembly (23 – 28 April), you can take part in our annual photo competition. Winners receive free registration to next year’s General Assembly! It’s that time of year again! Yes, today, the 13 January, the thirteenth annual EGU photo competition opened for submissions!! Until 31 March, every participant …[Read More]
Would you like to join me on a little trip up North today? We will be visiting a small community in the Canadian high Arctic – a community built on permafrost ground. This sounds pretty cool in the first place, but brings along quite a few challenges that most of us probably do not have …[Read More]
We are looking forward to celebrating another excellent exhibition of soil science at this year’s EGU General Assembly. Of course, very little soils research could take place without the work carried out by technicians, laboratory assistants, and research support staff. This monthly blog post is our opportunity to thank these key individuals, and their tireless …[Read More]
Introduction In 2022 I was asked to put together a virtual field trip looking at carbon sequestration (CCS). We are particularly lucky in Alberta in having three excellent Cambrian targets for CCS including the Basal Cambrian Sandstone, currently being used for CCS in Shell’s QUEST project, quartzites of the Deadwood Formation (being utilized for a …[Read More]
Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China …[Read More]
A blood moon occurs during a total lunar eclipse. The sunlight falling through the air layers of the Earth’s atmosphere is refracted inwards, whereby especially the short-wave blue components are weakened by scattering. The long-wave red components, on the other hand, still reach the moon, which leads to the red colouring. Photo by Simon Fuhrmann …[Read More]
