Trying to juggle teaching, advising, publishing, finding a new (or permanent) job, relocating, attending conferences, and actually doing research sometimes requires more hours in the day than exist (oh and that global pandemic situation is sticking around). Additionally, many scientists have children or are starting a family at the same time as maintaining and building a career. In this week’s blo ...[Read More]

Climate Change & the Cryosphere: Fjord sediments reveal how melting ice impact the marine ecosystem

It is scary how fast the Greenland Ice Sheet is melting and how much freshwater it is discharging to the coastal areas around Greenland. This freshening is having a serious impact to coastal marine primary production, which is the foundation of the Arctic marine food web. Now, because of increased melting and freshwater discharge, we need to understand how coastal ecosystems will react. How will A ...[Read More]

The Polar Amplifier

It’s no secret that the Arctic is warming faster than the rest of the planet, but why? Polar Amplification (often called Arctic Amplification) is the mechanism at play. In this week’s blog, we find out about its origins and why it happens. Early Discoveries In 1969, Russian scientist Mikhail Budyko and US scientist William Sellers discovered independently that the increase in greenhouse gases comb ...[Read More]

I have just returned from nearly three months in Nuuk, the capital of Greenland, where I was doing my PhD placement at Asiaq Greenland Survey. Read on to find out what science I got up to… everything from mapping mountain glacier snowline change to avalanches! How do you map glacier snowline evolution? During my PhD research placement, I was working at Asiaq Greenland Survey in their Hydrolo ...[Read More]

The EverDrill project: shedding light on the interior of a Himalayan debris-covered glacier

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 by the UK Natural Environment Research Council, aimed to fill this kn ...[Read More]

Will the ice break out? – a story from the farthest north ice trails

"For over two decades, the sea ice group at the University of Alaska has worked with the community of Utqiaġvik, establishing an integrated observing network. This network includes local observations, a coastal radar system to monitor ice conditions, an in-situ mass balance site monitoring environmental change such as ice growth and snow cover, and the mapping of community sea ice trails." In thi ...[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 wrote a photo-novel to tell her sons and all of you about life and science at ...[Read More]

Women of Cryo V: Women and Glaciers in the Chilean Andes (Part I)

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 a series of blog posts we hope to raise the voice of women in th ...[Read More]

Climate change and the Cryosphere – With ice we are also losing a piece of our cultural heritage: a glaciologist’s perspective

Climate change and the Cryosphere – With ice we are also losing a piece of our cultural heritage: a glaciologist’s perspective
The most famous glacier of the Dolomites (in the Eastern Alps): the Marmolada glacier. Its retreat has been ongoing for over a century and the glacier has now become a distant memory of what it used to be at the end of the Little Ice Age, in the late 19th century. [Credits: Giovanni Baccolo]

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 about one of the less talked about impact of glacier decline: the loss of culture and knowledge r ...[Read More]

Of Polar Bears and Sediment Cores: a Scientific Cruise in the Arctic

Of Polar Bears and Sediment Cores: a Scientific Cruise in the Arctic
One of the most stunning views of the trip, and one every glaciologist dreams of: a calving front in the sunshine. This is the terminus of Etonbreen, a glacier that is part of the Austfonna ice cap, an ice cap located on the island of Nordaustlandet, northeastern Svalbard. Photo credit: Agust Gustavsson.

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 late August, a group of 16 students, 4 prof ...[Read More]
