Members of the media, public information officers and science bloggers are now invited to register for the meeting free of charge. EGU22 will be held from 23-27 May, 2022 both in-person (Vienna, Austria) and online.
For the first time, scientists measure oxygen flow into the deep ocean interior of the Labrador Sea between Canada and Greenland. They studied how much oxygen absorbed by the sea each winter makes it into the deep, fast-flowing currents that ultimately transport it across the globe. The study was published today in Biogeosciences.
Are you an Early Career Scientist in the geosciences wanting to share your work with wider non-academic audiences? This EGU sponsored science writing workshop can help you to develop the specific skills for writing popular articles and interacting effectively with the media, led by tutors who work as science journalists and broadcasters. Places are limited to 30 people, so apply before 14 February to secure your spot.
The annual General Assembly will now be held on 23-27 May 2022 due to changing rules for events in Austria and concerns over high COVID-19 infection rates in Europe
New computer model simulations identify widespread changes in climate variability under sustained anthropogenic forcing. Researchers ran multiple simulations over the period of 1850-2100, working with a “business-as-usual” scenario for strong emissions of greenhouse gases over the 21st century. The study was published today in Earth System Dynamics.
The interplay between dissolution, precipitation and transport is widely encountered in porous media, from CO2 storage to cave formation in carbonate rocks. We show that dissolution occurs along preferential flow paths with high hydraulic conductivity, while precipitation occurs at locations close to yet separated from these flow paths, thus further funneling the flow and changing the probability density function of the transport, as measured on the altered conductivity field at various times.
Understanding tidal hydrodynamics is essential for water resources management in estuarine environments. In this study, we propose an analytical model to examine the fortnightly water level variations due to tidal motions alone in tide-dominated estuaries. Details of the analytical model show that changes in the mean depth or length of semi-arid estuaries affect the fortnightly tide amplitude, which has significant potential impacts on the estuarine ecosystem management.
This paper describes a new instrument for quantifying the physical characteristics of hydrometeors such as snow and rain. The device can measure the mass, size, density and type of individual hydrometeors as well as their bulk properties. The instrument is called the Differential Emissivity Imaging Disdrometer (DEID) and is composed of a thermal camera and hotplate. The DEID measures hydrometeors at sampling frequencies up to 1 Hz with masses and effective diameters greater than 1 µg and 200 µm.
Note: Spoilers Ahead! If you haven’t already seen it, go and watch Don’t Look Up – and then come back to this blog to find out what was done well and what else the scientists could have done to better connect and communicate with the policymakers involved! Don’t Look Up gives us a terrifying example of what could happen when policymakers ignore the science. The film tells the story of two astronomers, PhD candidate Kate Dibiasky and her supervisor Dr …
When we think of lightning, it is often accompanied by warm summer nights, tropical storms and a sticky feeling when we try to sleep. However, lightning also happens in the cold Arctic, and is even increasing in frequency. But how and why? And why does that matter? What is lightning? Lightning is caused by a difference in electrical charge between the cloud and the air, nearby clouds, or the ground (see image below). It can get really hectic inside a …
We are all underpaid and underappreciated. That is almost the dictionary definition of academic jobs. We bounce from one barely acceptable contract to the next, hoping to finally land a tenure-track position that allows us to swim in money like Scrooge McDuck. But before that, science itself should be its own reward and sustenance. Sometimes though, we hear from a friend of a friend about a colleague that got a promotion or a pay raise. Whether these legends are grounded …
