The tenth annual EGU photo competition opens on 15 January. Up until 15 February, every participant pre-registered for the General Assembly can submit up to three original photos and one moving image on any broad theme related to the Earth, planetary, and space sciences. Simply upload your photos to imaggeo and choose the option to include them in the photo contest.

Quantifying new water fractions and transit time distributions using ensemble hydrograph separation: theory and benchmark tests

How long does it take for raindrops to become streamflow? Here I propose a new approach to this old problem. I show how we can use time series of isotope data to measure the average fraction of same-day rainfall appearing in streamflow, even if this fraction varies greatly from rainstorm to rainstorm. I show that we can quantify how this fraction changes from small rainstorms to big ones, and from high flows to low flows, and how it changes with the lag time between rainfall and streamflow.

Global atmospheric CO2 inverse models converging on neutral tropical land exchange, but disagreeing on fossil fuel and atmospheric growth rate

We have compared global carbon budgets calculated from numerical inverse models and CO2 observations, and evaluated how these systems reproduce vertical gradients in atmospheric CO2 from aircraft measurements. We found that available models have converged on near-neutral tropical total fluxes for several decades, implying consistent sinks in intact tropical forests, and that assumed fossil fuel emissions and predicted atmospheric growth rates are now the dominant axes of disagreement.

Demystifying academics to enhance university–business collaborations in environmental science

Worldwide there is intense interest in converting research excellence in universities into commercial success, but there has been scant attention devoted to exactly how individual scientists’ workload and incentive structures may be a key barrier to this. Our work reveals the real challenge posed by a time-constrained university culture, better describes how work with business might fit into an academic job, and gives tips on working together in anuser guidefor scientists and (re)insurers.

A multi-technology analysis of the 2017 North Korean nuclear test

On 3 September 2017 official channels of the Democratic People’s Republic of Korea announced the successful test of a nuclear device. This study provides a multi-technology analysis of the 2017 North Korean event and its aftermath using a wide array of geophysical methods (seismology, infrasound, remote sensing, radionuclide monitoring, and atmospheric transport modeling). Our results clearly indicate that the September 2017 North Korean event was in fact a nuclear test.

Image of the Week - What’s Hot in the Cryosphere? A 2018 review

Every year, humanity understands more and more about a remote and unforgiving component of the Earth system – the cryosphere. 2018 has been no exception, and in this blog post we’ll take a look at some of the biggest scientific findings of cryospheric science in 2018. We will then look forward to 2019 and beyond, to see what the future holds for these rapidly changing climate components. The Cryosphere at 1.5°C warming In 2018, the IPCC (Intergovernmental Panel on Climate …


A belated happy new year!

A belated happy new year!

It was that time of the year again: holidays! Time to take a break from work, relax, and see all your friends and family again. The blog team is no different: we took a break from blogging for a little while as well, so you had to survive the holidays without us! Did you survive Christmas day without one of our blogposts? It must’ve been dreadful, I know, but that’s life! Luckily, we have some good news: we are back …


GeoTalk: Alena Ebinghaus, Early Career Scientist Representative

GeoTalk: Alena Ebinghaus, Early Career Scientist Representative

<p>In addition to the usual GeoTalk interviews, were we highlight the work and achievements of early career scientists, this month we’ll also introduce one of the (outgoing) Division early career scientist representatives (ECS). The representatives are responsible for ensuring that the voice of EGU ECS membership is heard. From organising short courses during the General Assembly, through to running division blogs and attending regular ECS representative meetings, their tasks in this role are varied. Their work is entirely voluntary and …
