Compared to the formation and evolution of the Earth’s surface, the ancient oceans receive little attention in geological history. However, understanding the rise and fall of the oceans of the past—or “ghost oceans”—can reveal crucial information about the evolution of our planet, the cryosphere included. Can oceans play a historical role in climate change? If water bodies had not existed, would w ...[Read More]

The most-read EGU journal articles in 2021!
This year EGU published more than 3,375 peer-reviewed articles in our 19 Open Access journals. Upon learning about this impressive number of articles, we wondered: which of these were the most popular? You can find out in the following list of the most-read article for each EGU journal. From rainfall-runoff prediction, tipping points and open source hazard mapping, to the use of language around fr ...[Read More]

Geomythology. The Sicilian Trilogy – Part I: Persephone on the endorheic Pergusa lake
If, in 2022, you still think that seasons depend on the Earth’s rotation around its tilted axis and around the Sun… you are surely right. However, in ancient times, the Greeks, and the Romans afterwards, thought it was due to an agreement between Zeus and Hades, to save Persephone from the Underworld. The sick love of Gods Persephone, daughter of Demeter, the Goddess of harvest and agricultu ...[Read More]

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?
The Indian Ocean Geoid Low is an enigmatic phenomenon in geodynamics. Many brain-storming hypotheses have been proposed in the last few decades to explain this geoid low. One popular idea argues that the high density lower mantle slabs contribute to this geoid low. Recent discoveries have shown that low-density anomalies from the African LLSVP region could have a more substantial influence on crea ...[Read More]

The Sassy Scientist – Whining Unleashed
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 collea ...[Read More]

Minerals and Art: a centuries-old connection
Since ancient times, colours have been fundamental for artistic expression: pigments have always been created from fruits, leaves-flowers, and minerals. During the centuries, new material discoveries and techniques increased the shades we can still see and use nowadays. Once upon a Prehistoric time… El Castillo Cave, in Spain, is one of the earliest known cave paintings, dated to more than 40,000 ...[Read More]

Camp Century re-visited: sediment from the bottom of a Cold War ice core reveals Greenland’s warm past
A Cold War nuclear-powered military base inside the Greenland Ice Sheet sounds like science fiction, but the science that came out of this U.S. army installation was anything but fiction. In last week’s EGU CR blog post, Paul Bierman and Amanda Schmidt discussed the advances made by the U.S. military in operating across the Greenland Ice Sheet that culminated in the establishment of Camp Century i ...[Read More]

Parenting in Academia: Challenges and Perspectives
Trying to juggle teaching, advising, publishing, finding a new (or permanent) job, relocating, attending conferences, and actually doing research sometimes requires more hours in the day than exist (oh and that global pandemic situation is sticking around). Additionally, many scientists have children or are starting a family at the same time as maintaining and building a career. In this week’s blo ...[Read More]
