Laboratory visualisation of solar wind interaction with Earth’s magnetic field. The Van Allen radiation belt, Earth’s magnetosphere, “bow shock” and a solar coronal hole can all be seen, and are emphasized with the ‘Planeterrella experiment‘, a vacuum chamber in the shape of a bell jar with the ‘Sun’ on the left (in the form of a large metallic sphere) and the ‘Earth& ...[Read More]

Should I… do a coding PhD when I don’t have much experience coding?
“The ideal applicant will have a strong background in coding.” I’m not sure if those were the exact words that advertised my PhD project, but a requirement of coding ability was certainly heavily implied. We’re used to hearing stories about job requirements in the professional world, but in my experience at least, we think much less about this in the academic sphere. I nearly didn’t apply to ...[Read More]

GeoPolicy: Europe’s Waste Policy – using Incinerator Bottom Ash and reducing landfill
Although you may not realise it, waste and the circular economy is an important topic for many geoscientists. Our consumption drives the need for resources and sustainable resource extraction, while disposing and reducing this waste requires a wide range of expertise and impacts the environments in which many scientists undertake their research. On a more personal level, understanding what happens ...[Read More]

Did you know … that liquid water can be held within a glacier?
Hidden below the surface of some glaciers, liquid water can be found within what is called the firn layer – the upper layer of a glacier where snow compacts into glacier ice. Liquid water may persist there for up to many years, forming what scientists call “firn aquifers.” While observations of seasonal firn aquifers have existed since the mid to late 1900s in several mountain glaciers, recent stu ...[Read More]

vEGU21: the EGU Game Jam has arrived!
This year once again the EGU General Assembly of 2021 will be going online, however unlike in 2020, for vEGU21 the Programme Committee, Council and other organising members have much more time to prepare this year. So in follow up to last year’s online stream of our very popular EGU Games Night, for 2021 we are delighted to introduce the EGU Games Jam – co-ordinated by the EGU Games fo ...[Read More]

The most-read NPG 2020 paper: “Effects of upwelling duration and phytoplankton growth regime on dissolved-oxygen levels in an idealized Iberian Peninsula upwelling system”
An emerging problem brought by climate change is the on-going deoxygenation of the world’s oceans. The fact that concentrations of dissolved oxygen have been/are declining in both open-ocean and coastal waters is becoming a major scientific and societal concern raised in the Kiel Declaration and in the IUCN (International Union for Conservation of Nature) 2019 report. Lower levels of dissolved oxy ...[Read More]

Geoscience for the Future with Dr Natasha Dowey
The Geosciences are at the forefront of the fight against climate change. It is Geoscientists who discovered it and explained it, and it is Geoscientists who work to understand it and its consequences. Geoscientists undoubtedly will be amongst those who will lead us to the solutions. However, it often seems that Geoscientists are solely associated with the extractive industries, a damaging false p ...[Read More]

Janet Vida Watson (1 September 1923 – 29 March 1985): The woman who could translate the story of Precambrian rocks into a crystal-clear message
On a late summer day in September 1923, Janet Vida Watson was born. With a father working in palaeontology and a mother who did research in embryology until her marriage, Janet grew up with science all around her. She went to South Hampstead High School, known for its science teaching and continued her education in General Science at Reading University. She graduated in biology and geology in 1943 ...[Read More]

GeoRoundup: the highlights of EGU Journals published during January!
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For January, the Divisions we are featuring are: Atmospheric Sciences (CR), and Earth and Space Science Informatics (ESSI). They are served by the journals: Geoscientific Model Development (GMD), Annales Ge ...[Read More]

120 years of the ‘Greenhouse Effect’
120 years ago in 1901, Swedish meteorologist Nils Ekholm used the term ‘greenhouse’ to describe the heating effect that a planet’s atmosphere has on the surface temperature of the planet, the first time that this now much-used and abused metaphor was published. He wrote: “The atmosphere plays a very important part of a double character as to the temperature at the earth’s surface, of which the one ...[Read More]
