An interview with Jean Holloway on the importance of mental health in graduate school

An interview with Jean Holloway on the importance of mental health in graduate school

Recent studies have shown that mental health conditions are far more common in graduate students than in the general public (e.g. Bolotnyy et al., 2020). Despite the prevalence, these issues are not something that are often openly discussed, and graduate students often don’t seek treatment. This week, we are interviewing Jean Holloway who aims to shed some light on her personal experience with som ...[Read More]

Education in glaciology: Witnessing the death of a glacier

Education in glaciology: Witnessing the death of a glacier

The Karthaus summer school on Glaciers and Ice Sheets in the Climate System has a long history of training many generations of PhD students, thus forming professional networks that have lasted throughout their careers. The Karthaus summer school has been described in detail in a previous Cryoblog post. Here we want to focus on the story of a glacier… Hochjochferner, a retreating glacier One ...[Read More]

Cryo History – How airborne glaciologists measured the movement of glaciers before the satellite era

Cryo History – How airborne glaciologists measured the movement of glaciers before the satellite era

Recent work published in my department at the Geological Survey of Denmark and Greenland (GEUS) focused on solid ice discharge into the ocean from the Greenland Ice Sheet from 1986 to 2017 (Mankoff et al. 2019). Solid ice discharge is the ice that is lost from a glacier as it flows towards the coast and eventually breaks off as icebergs into the ocean (i.e. calving). Solid ice discharge is an impo ...[Read More]

Cryo Adventures – What’s currently going on in Antarctic science?

As Christmas gets closer, days are getting shorter in the northern hemisphere. A good excuse to get cosy inside on the sofa, drinking tea and eating Christmas biscuits. Meanwhile, a few thousand of scientists are heading “South”, to Antarctica, where the lengthening days provide the perfect conditions to conduct a whole variety of scientific field expeditions… Science in Antarctica Just last ...[Read More]

Did you know… about the fluctuating past of north-east Greenland?

Did you know… about the fluctuating past of north-east Greenland?

Recent geological data shows that during a very cold phase of our Earth’s climate (between 40,000 and 26,000 years ago), there was a huge expansion of polar ice sheets, yet the north-eastern part of the Greenland ice sheet was less extensive than today. How could this have occurred? In this post we shed light on the potential causes of this ice sheet behaviour. What do we know about present- ...[Read More]

Cryo-adventures – Behind the scenes of cryo-fieldwork

As the Arctic is warming faster than the global average, Arctic glaciers are rapidly melting. My research is about the fate of glacial organic carbon when the ice containing it melts. To investigate these processes, I travelled to several glaciers, an activity full of challenges… and rewards! My research Glacier ice covers about 11% of Earth’s land surface, and contains within it a globally ...[Read More]

Did you know? – Proglacial lakes accelerate glacier retreat!

In a global context, New Zealand’s small mountain glaciers often get overlooked and yet they are a beautiful part of New Zealand’s landscape. They are the water towers for the South Island and an essential part of its tourism, thanks to a few undeniable heroes (Frans Josef and Fox Glaciers), but sadly, they may not be as prominent in the future. In this post we review the state of modern glaciatio ...[Read More]

Cryo-Comm – Degrading Terrains

  Beneath dusted peaks of mountain dew A dense and rigid backcloth skulks, Worn down and compacted with Fractured decades of aged powder; Trodden into rocky outcrops To lie barrenly against This frozen, ancient soil. Subtle shifts of these forgotten rocks Ripple across subterranean sediments, Dislodging once-stable foundations That now cascade like an ocean; Echoing across the fragile firmame ...[Read More]

Cryo-Adventures – The Glacial Isostatic Adjustment (GIA) Training School: Personal and Virtual Attendance

The 2019 Glacial Isostatic Adjustment (GIA) Training School was hosted by Lantmäteriet (the Swedish Mapping, Cadastral, and Land Registration Authority) in Gävle, Sweden from 26 – 30 August. GIA is the response of the solid Earth to past and present-day changes of glaciers and ice sheets. Research interests in GIA span the geosciences: from regional planning applications (reclamation/flooding of l ...[Read More]
