Image of the Week — Climate change and disappearing ice

The first week of the Climate Change summit in Bonn (COP 23  for those in the know) has been marked by Syria’s decision to sign the Paris Accord, the international agreement that aims at tackling climate change. This decision means that the United States would become the only country outside the agreement if it were to complete the withdrawal process vowed by President Trump. In this context ...[Read More]

GeoSciences Column: The dirty business of shipping goods by sea

“Above the foggy strip, this white arch was shining, covering one third of the visible sky in the direction of the ship's bow,” he explains. “It was a so-called white, or fog rainbow, which appears on the fog droplets, which are much smaller then rain droplets and cause different optic effects, which is a reason of its white colour.”

Shipping goods across the oceans is cost-effective and super-efficient; that’s why over 80% of world trade is carried by sea (according to the International Maritime Organisation). But the shipping industry also contributes significant amounts of air pollutants to marine and coastal environments. A new study, published in the EGU’s open access journal Earth System Dynamics, reports on concentratio ...[Read More]

Community advice to young hydrologists, Part 1

Community advice to young hydrologists, Part 1

We at Water Underground loved reading Young Hydrologic Society’s post titled “Community advice to young hydrologists” – an advice column written by a network of established scientists in the field. We appreciated the column so much, in fact, that we have decided to re-blog the post to you (with YHS’s consent, of course). We’ve split up their post by question, and have added in hyperlinks to all co ...[Read More]

Heather Britton: Sinkhole Occurrence and Mitigation

Heather Britton: Sinkhole Occurrence and Mitigation

Sinkholes are often overlooked geohazards which, although far less destructive in the short-term than earthquakes and landslides, can be catastrophic to life and severely impact the built environment. This post will explore how these features form and the strategies that have been adopted to predict their appearance. It will also consider how urbanisation in karstic areas is accelerating sinkhole ...[Read More]

Five top tips to apply for small grants

Stephanie Zihms, the ECS Representative for the EMRP Division (and incoming Union Level Representative) has applied for a range of small scale grants (<£15,000, ca. 16,965€). At this year’s General Assembly, she was one of two speakers at the ‘How to write a research grant’ short course, where she shared  insights from her successes and failures. In today’s post she tells us about the top five ...[Read More]

Imaggeo on Mondays: Of ancient winds and sands

Snippets of our planet’s ancient past are frozen in rocks around the world. By studying the information locked in formations across the globe, geoscientist unpick the history of Earth. Though the layers in today’s featured image may seem abstract to the untrained eye, Elizaveta Kovaleva (a researcher at the University of the Free State in South Africa) describes how they reveal the secrets of anci ...[Read More]

Try something different at EGU 2018– choose a PICO session!

Some of the sessions scheduled for the upcoming EGU General Assembly are PICO only sessions. This means that, rather than being oral or poster format, they involve Presenting Interactive COntent (PICO). The aim of these presentations is to highlight the essence of a particular research area – just enough to get the audience excited about a topic without overloading them with information. What’s gr ...[Read More]

Eyes on the Sun

The Sun is a complex, dynamic ball of plasma which influences our lives. Studying the Sun is challenging because each of its layers have different composition, physics and wavelengths of emssion. Moving outwards from the photosphere (visible surface of the Sun), we have the chromosphere and the corona (hottest outermost layer). The solar plasma is in constant motion much like fiercely boiling wate ...[Read More]
