New study: Fracking prompts global spike in atmospheric methane

  • Press release
  • 14 August 2019

As methane concentrations increase in the Earth’s atmosphere, chemical fingerprints point to a probable source: shale oil and gas, according to new Cornell University research published today in Biogeosciences, a journal of the European Geosciences Union.

Higher education teaching of geoscience: how can the EGU help?

  • EGU news
  • 8 July 2019

EGU’s Committee on Education aims to provide support for higher education, from organising workshops to providing networking opportunities for all those teaching geoscience in higher education. We invite PhD students, postgraduates, research fellows, academic staff and any others teaching geoscience in higher education to fill in a short survey to help us understand the role EGU could play in further supporting higher education.

Hybrid-Vlasov modelling of nightside auroral proton precipitation during southward interplanetary magnetic field conditions

When the terrestrial magnetic field is disturbed, particles from the near-Earth space can precipitate into the upper atmosphere. This work presents, for the first time, numerical simulations of proton precipitation in the energy range associated with the production of aurora (∼1–30 keV) using a global kinetic model of the near-Earth space: Vlasiator. We find that nightside proton precipitation can be regulated by the transition region between stretched and dipolar geomagnetic field lines.

How can geologic decision-making under uncertainty be improved?

In this paper, we outline the key insights from decision-making research about how, when faced with uncertainty, humans constrain decisions through the use of heuristics (rules of thumb), making them vulnerable to systematic and suboptimal decision biases. We also review existing strategies to debias decision-making that have applicability in the geosciences, giving special attention to strategies that make use of information technology and artificial intelligence.

Improved methodologies for Earth system modelling of atmospheric soluble iron and observation comparisons using the Mechanism of Intermediate complexity for Modelling Iron (MIMI v1.0)

MIMI v1.0 was designed for use within Earth system models to simulate the 3-D emission, atmospheric processing, and deposition of iron and its soluble fraction. Understanding the iron cycle is important due to its role as an essential micronutrient for ocean phytoplankton; its supply limits primary productivity in many of the world’s oceans. Human activity has perturbed the iron cycle, and MIMI is capable of diagnosing many of these impacts; hence, it is important for future climate studies.

CO2 effects on diatoms: a synthesis of more than a decade of ocean acidification experiments with natural communities

Diatoms are a group of phytoplankton species responsible for ~ 25% of primary production on Earth. Ocean acidification (OA) could influence diatoms but the key question is if they become more or less important within marine food webs. We synthesize OA experiments with natural communities and found that diatoms are more likely to be positively than negatively affected by high CO2 and larger species may profit in particular. This has important implications for ecosystem services diatoms provide.

Educators: apply now to take part in the 2020 GIFT workshop!

The General Assembly is not only for researchers but also for teachers and educators with an interest in the geosciences. Every year the Geosciences Information For Teachers (GIFT) workshop is organised by the EGU Committee on Education to bring first class science closer to primary and high school teachers. The topic of the 2020 edition of GIFT is ‘Water in the solar system’. This year’s workshop will be taking place on 4–6 May 2019 at the EGU General Assembly in …


Trieste, where the word Karst originates

Trieste, where the word Karst originates

The city of Trieste lies in north-eastern Italy along the border with Slovenia. It is positioned at the corner point between the Romance, Germanic and Slavic worlds and serves as an important seaport in the region. It is fascinating for both its history and geology. My relationship with Italy’s town of Science, as Trieste is often referred to, started about a year ago. I got the opportunity to start a PhD focused on imaging evaporates, at the University of Trieste …


Space travel: arrogance or vision?

Space travel: arrogance or vision?

This week, Caroline Dorn, Ambizione Fellow at the University of Zurich, tells us her view on space travel and why we shouldn’t pack our bags just yet. Space exploration is experiencing a new boom, a come-back since the 60s & 70s! First discoveries of planets outside our solar system in the 90s have set the foundations of a new discipline that is exoplanet science – the field in which I am working in. I enjoy that there is a lot …
