©LEt’sGO to Antarctica !

With the current situation, polar fieldwork might be/have been cancelled and we have a suggestion to remedy your field-blues… Why not use ©LEGO to pretend you’re back in the field with the added bonus that you get to be in the warmth and comfort of your home! Here, we’ve re-enacted radar fieldwork that took place a year and a half ago in Antarctica… But first, let’s start with some backgroun ...[Read More]

Back to the Front – Larsen C Ice Shelf in the Aftermath of Iceberg A68!

Back to the Front – Larsen C Ice Shelf in the Aftermath of Iceberg A68!

Much of the Antarctic continent is fringed by ice shelves. An ice shelf is the floating extension of a terrestrial ice mass and, as such, is an important ‘middleman’ that regulates the delivery of ice from land into the ocean: for much of Antarctica, ice that passes from land into the sea does so via ice shelves. I’ve been conducting geophysical experiments on ice for over a decade, using mostly s ...[Read More]

Image of Week: Inside the Greenland Ice Sheet

Image of Week: Inside the Greenland Ice Sheet

The image shows a cross section of the Greenland Ice Sheet, where a recent study by MacGregor et al. have mapped the layers imaged by radar. Thanks to ice core measurements the age of the layers have been determined, and in the image the layers from the Holocene period (the past 11.700 years) are shown in green. The ice formed during the last ice age, that spanned 11.700 to 115.000 years ago are c ...[Read More]

My first journey to Antarctica – Brice Van Liefferinge

My first journey to Antarctica – Brice Van Liefferinge

19 November 2014, the Iliuchine 76 gently lands on the runway of the Russian Antarctic station, Novolazarevskaya, in Dronning Maud Land. For the first time, I’m in Antarctica! It is 4 o’clock in the morning and we need to hurriedly offload 2 tons of material intended for our field mission near the Belgian Princess Elisabeth Station. I’m deeply impressed by the landscape although it is dotted with ...[Read More]

Glaciers on Mars

Glaciers on Mars

“I did not know that there is water on Mars!” This a sentence I hear surprisingly often when I talk about glaciers on Mars. In fact, it has been known for some time that water exists in the form of ice and water vapour on the planet. For example, water ice layers several kilometres thick cover the Martian poles, and the ground close to the Polar Regions has permafrost patterns very similar to what ...[Read More]
