How can scientists see ice underground? Recent study reveals how!

When it comes to peering beneath the Earth’s surface, geophysicists have an arsenal of high-tech tools at their disposal. But what happens when you need to track something as elusive as underground ice forming and melting in real time? Enter borehole Ground-Penetrating Radar (GPR), the underground detective that helped Peter Jung and his colleagues image frozen subsurface volumes in an experimenta ...[Read More]

A 12-meter sediment core reveals secrets of the Arctic’s past climate

A 12-meter sediment core reveals secrets of the Arctic’s past climate

Extracted from a depth of 2,500 meters, a giant 12-meter long marine sediment core from the Fram Strait, between Svalbard and Greenland, preserves a climate record spanning up to 400,000 years. Its sediment layers offer crucial insights into the Arctic’s past, helping Dr Jochen Knies and his research team answer two important question: Was the Arctic ever ice-free during past warm periods? W ...[Read More]

GeoTalk: meet Alessandro Silvano, winner of the 2024 Ocean Sciences Division Outstanding ECS Award!

Alessandro Silvano

Hello Alessandro. Thank you for joining me for this edition GeoTalk! Could you tell our readers about your background before we dive in?  I am an oceanographer based at the University of Southampton (UK). I am interested in polar oceanography and ice-ocean interactions. The focus of my work is to understand the processes that control ocean heat transport toward rapidly-melting Antarctic glaciers. ...[Read More]

Past ice and future predictions – scanning and drilling the changing Antarctic ice

In front of the blue EGU press conference background, Olaf Eisen (left), Robert Larter (middle) and Emma Pearce (right) are engaged in discussion.

Did you know that some of the scientists of each General Assembly get invited to a press conference to face a group of curious journalists? I did not – but as press assistant for the #EGU24, I had the unique chance to attend the press conference “Unveiling Antarctica’s secrets: new research brings us one step closer to predicting the future of the icy continent”. Prominent scientists (Fig.1) ...[Read More]
