Sunshine, ice cores, buckets and ALE: Antarctic Fieldwork

Sunshine, ice cores, buckets and ALE: Antarctic Fieldwork

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]

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]

Image of the week : formation of an ice rise

Image of the week : formation of an ice rise

Deglaciation and formation of an ice rise with the ice-sheet model BISICLES.  The simulation starts with an ice sheet in steady state that overrides a topographic high in the bed, close to the calving front. The sea level is then forced to rise steadily with 1 cm per year during 15 thousand years, and the simulation goes on until the ice sheet reaches steady state. The animation below shows that t ...[Read More]

Image of the Week: Greenland Ice Streams

Image of the Week: Greenland Ice Streams

This image is from the west coast of Greenland and it shows several glaciers flowing towards the sea (upper part of the image), transporting ice into the ocean. The colours show the velocity of the ice. As the ice gets nearer to the coast it speeds up reaching speeds over 15m/day. The velocities were calculated using two Sentinel-1A radar scans from 3 and 15 January 2015. You can download a high r ...[Read More]

Science and Shovels: Traversing across the Greenland Ice Sheet.

Science and Shovels: Traversing across the Greenland Ice Sheet.

Moving 150 tonnes of equipment more than 450km across the Greenland Ice Sheet sounds like a crazy idea. In that context, moving a 14-metre high, dome-shaped, wooden structure seems like a minor point, but it really is not. I do not think I realised what an awesome and awe-inspiring project I was part of, until I was out there, in the middle of the blindingly white ice sheet, and I saw the enormous ...[Read More]

Ice Nomads: The iSTAR traverse of Pine Island Glacier, West Antarctica

It’s the 2nd December 2013 and I find myself in one of those rare occasions in life where I feel I need to pinch myself to see if I’m dreaming. Why? Somehow I’m in control of a British Antarctic Survey De Havilland Twin Otter aircraft flying over the white featureless expanse of the West Antarctic Ice Sheet. I’m part of a team of 12 heading to Pine Island Glacier, a remote ice stream 75°S and arou ...[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]

Happy birthday to the Cryoblog!

Collage of four people with the heading

  The EGU Cryosphere Blog is now 10 years old: Happy Birthday! It all started in December 2014 with this blog post from Nanna Karlsson, and now counts 452 blog posts across 25 blog categories, including winning three Best EGU blog posts (2016, 2019 and 2021). 881 different (hash)tags were used in our blog posts, with way more counts on Antarctica and climate than the Arctic. Since the start, ...[Read More]

Did you know? Machine learning can help us understand the cryosphere!

A bar chart showing in which years how many publications included machine learning.

    Recently, Machine Learning (ML) has emerged as a powerful tool within cryospheric sciences, offering innovative and effective solutions for observing, modelling and understanding the frozen regions of the Earth. From learning snowfall patterns and predicting avalanche dynamics to speeding up the process of modelling ice sheets, ML has transformed cryospheric sciences and bears many o ...[Read More]

Dreaming & reading about fieldwork – summer blog break 2024

A person is kneeling down at a brown pond, all covered in mosquito net, waterproof gear, kitchen gloves and a pancake flipping spatula.

  As we are starting into our annual blog summer break, we reflect on what summer can mean for polar researchers (including some fieldwork saudades). As an Arctic or Alpine cryo-scientist, chances are that you are somewhere in between vacation, fieldwork or trying to work through data while everyone else is free. If you, like us, did not have your vacation yet or do not have any fieldwork com ...[Read More]
