Scientists struggle to get ice samples from the depths of glaciers where fundamental pieces of information about the climate of Earth are stored. But in many places around the periphery of the Greenland Ice Sheet, you don’t need to drill a deep ice core to obtain ancient ice, you can simply walk across the ice sheet’s margin and look at the layered ice surface. There you can read the ice as though ...[Read More]

Image of the Week – The Sound of an Ice Age

Nanna B. Karlsson December 30, 2016

The blue curves show the δOxygen-18 values for NorthGRIP in Greenland (top) and WAIS in Antarctica (bottom) for the last 20,000 years. The black dots are 1,000 years values, and the far left hand side of the curves are present day values.

New Year’s Eve is just around the corner and the last “image of the week” of 2016 will get you in the mood for a party. If your celebration needs a soundtrack with a suitably geeky touch then look no further. Here is the music for climate enthusiasts: The sound of the past 60,000 years of climate. Scientist Aslak Grinsted (Centre for Ice and Climate, University of Copenhagen, Denmark) has transfor ...[Read More]

This is it! The new European horizon 2020 project on Oldest Ice has been launched and the teams are already heading out to the field, but what does “Old Ice” really mean? Where can we find it and why should we even care? This is what we (Marie, Olivier and Brice) will try to explain somewhat. Why do we care about old ice, ice cores and past climate? Unravelling past climate and how it responded to ...[Read More]

My Antarctic adventure started from Punta Arenas at the bottom of Chile, opposite Tierra del Fuego, on New Years Eve 2014 after a long journey from Heathrow via São Paulo and Santiago. Punta Arenas Punta Arenas is where Shackleton organised the rescue of his men from Elephant Island after his voyage to South Georgia in the James Caird. It is also where I met my PhD supervisors Chris Fogwill and Ch ...[Read More]
