We know that glaciers are actively responding to climate change, but what is happening on the inside? The conditions within a glacier strongly influence its behaviour, but the deep and dark depths of a glacier are difficult to access – we know very little about this remote environment. The EverDrill project (2016 – 2019), funded …[Read More]

Will the ice break out? – a story from the farthest north ice trails
“If there is a pan of ice that hits the shorefast ice from the North, it can take off a sheet of ice, and you can go with it.” The serious expression of the 67-year-old whaling captain made it impossible to mistake the potential risk associated with the ancient tradition of spring whale hunting from …[Read More]
Cryo-adventures: Ninja goes south – Life and science onboard an icebreaker in the Weddell Sea (Antarctica)
Hello there! I’m Ninja – a curious little LEGO-figure who doesn’t know much about the cryosphere, but who’s learning! Maybe you read about me in the blogpost by ice sheet modeler Petra Langebroek a few years ago? She brought me to the ice-core drilling camp called EASTgrip, on top of the Greenland icesheet. Together, we …[Read More]
Women of Cryo V: Women and Glaciers in the Chilean Andes (Part I)
Women make up 50.8% of the worlds population, yet fewer than 30% of the world’s researchers are women. Of this percentage, BAME (Black Asia and Minority Ethnic) comprise around 5%, with less than 1% represented in geoscience faculty positions. The divide between women in the population and women in STEM needs to be addressed. Through …[Read More]
Climate change and the Cryosphere – With ice we are also losing a piece of our cultural heritage: a glaciologist’s perspective
Glaciers are shrinking and disappearing in many regions of the Earth. Did you know? I am joking of course. We are flooded with news talking about this. The decline of glaciers has manifold and severe consequences and is one of the most powerful icons of climate change. Here I want to talk a little bit …[Read More]
Of Polar Bears and Sediment Cores: a Scientific Cruise in the Arctic
Through the scientific excursion part of the University Centre in Svalbard (UNIS) course ‘Arctic Late Quaternary Glacial and Marine Environmental History’, a few lucky grad students got to visit Nordaustlandet, northeastern Svalbard. This is the story of our research adventure in this beautiful, remote part of the Arctic. On a bright and early morning in …[Read More]
It’s getting hot in here: Ancient microbes in thawing permafrost
Did you know that the oldest organism on Earth is believed to be a microorganism found in 3-million-year-old permafrost in Siberia? There, it was living at a cosy average temperature of -10 °C at 14 m depth. Or did you hear that some other Arctic soil microorganisms can happily live at extreme temperatures down to …[Read More]
Vernagtferner: My First Encounter with an Alpine Glacier
In July 2021, together with a group of MSc students from the University of Bremen, I set off from the flat plains of Northwest Germany and embarked on a journey to the mountainous regions of Austria, with the Vernagtferner Glacier as our final destination. My aim was to learn as much as I could in …[Read More]
Cryo-Adventures – Hunting snow algae in the Alps
We are used to think of algae as marine or lacustrine organisms, but they are actually able to thrive also on the cryosphere. In a previous post, we learnt how snow algae live and reproduce on snow. Now we will explore how and why scientists study snow algae, and how social media can be used …[Read More]
Women of Cryo IV: Virginia ‘Ginny’ Fiennes (1947 – 2004)
Women make up 50.8% of the worlds population, yet fewer than 30% of the world’s researchers are women. Of this percentage, BAME (Black Asia and Minority Ethnic) comprise around 5%, with less than 1% represented in geoscience faculty positions.
