Heard Island Glaciers Are Shrinking Faster Than Ever! Here’s what you need to know.

In this blog post Dr Levan Tielidze from Monash University and Securing Antarctica’s Environmental Future shares insights from a new glacier assessment of Heard Island. Although rarely visited and largely unknown, Heard Island plays an outsized role in understanding how the Southern Ocean cryosphere is responding to global warming. The island is one of the few sub-Antarctic locations with active g ...[Read More]

Cryo Adventures – Discovering the beauty of polar winter

Cryo Adventures – Discovering the beauty of polar winter

Only one month after starting my PhD, I found myself in a tiny plane flying over one of the most beautiful and breathtaking landscapes I’ve ever seen. I was on the way to the northernmost settlement in the world – the research village Ny-Ålesund. What I expected from the trip: cold temperatures, darkness, and lots of snow. What I found instead: stunning views, magical colors, friendly people, and ...[Read More]

Did you know: Soot is a melting agent for glaciers in Peru and China

July 25, 2025
Collecting snow samples from the Puruogangri Ice Cap on the Tibetan Plateau, China.

Mountain glaciers are melting rapidly due to global warming. This process is being intensified by increasingly extreme natural events, such as forest fires and air pollution from human activities. One of the main culprits is a tiny but powerful pollutant called black carbon (commonly known as soot) which darkens the surface of the snow and makes it met faster under the sun. But how much of this po ...[Read More]

The Proglacial Puzzle: Sampling of Glacier-fed Lakes in Greenland

Would you like to follow the endeavours of a small team working in the ice-marginal terrain in South-West Greenland? They set out to investigate proglacial lakes using sediment coring, water sampling and gas collections (figure 1), aiming to better understand methane dynamics, proglacial terrain development and the environmental drivers behind methane production in glacially influenced lake system ...[Read More]

Tracking the Footprints of a Vanishing Glaciers in the Greater Caucasus

June 13, 2025
Aerial image showing the climate change impact on small glaciers in the central Greater Caucasus, Georgia. Slopes are extensive deposits of moraines and loose rock debris, left behind by retreating glaciers. A small glacial lake (near the center-bottom of the image) fed by meltwater from the surrounding ice and snow was developed after glacier retreat [Credit: Levan Tielidze].

In this week’s blog, Levan Tielidze tells us about his recent glacier study from the Greater Caucasus. By combining geomorphology, remote sensing, and historical cartography, the team reconstructed nearly 200 years of glacier and climate change across one of the world’s most dynamic cryospheric frontiers. Glaciers’ transformation provides a high-resolution archive of post-Little Ice Age climate dy ...[Read More]

A Scientific Quest from Australia to Antarctica

May 29, 2025
A group of 10 individuals forming the team for the fieldwork

In this week’s blog, Levan Tielidze tells us about his participation in a scientific expedition to Dronning Maud Land, Antarctica, during the 2024–2025 field season. The journey, commencing in Australia and passing through South Africa, led him to the “surreal” and “awe-inspiring” Antarctic landscape. The team, a collaborative effort from Monash University, and the Un ...[Read More]

Field notes from the Chhota Shigri Glacier: A journey of science and survival in the Himalaya

January 10, 2025
Weather station on the snow

I’m Himanshu Kaushik, a PhD student working under the guidance of Dr. Mohd Farooq Azam at the Indian Institute of Technology Indore (India). Seven years ago, I took my first steps onto the Chhota Shigri Glacier (CSG) in the Indian (Western) Himalaya, and it felt like stepping into another world. Surrounded by the towering peaks, it seemed otherworldly and humbling. After that first expeditio ...[Read More]

Uncovering Antarctica’s hidden subglacial lake network with satellite altimetry

Uncovering Antarctica’s hidden subglacial lake network with satellite altimetry

    Measuring ice surface elevation changes with satellite laser altimeters flying hundreds of kilometres above Earth tells us where the Antarctic and Greenland ice sheets are thinning or thickening and how much they contribute to sea level rise. Beyond that though, it can also reveal hidden activity of subglacial lakes filling and draining beneath the ice and meltwater rivers flowing ou ...[Read More]

Crossing borders – Glacier fieldwork at Sulitjelma/Salajekna

Crossing borders – Glacier fieldwork at Sulitjelma/Salajekna

The time I first set foot at the university, I didn’t expect that two weeks later I would be looking at a backpack more than half my size, turning my back to the shelter of our rental car and walking almost 100 km in the Norwegian Arctic. Howling winds, heavy backpacks, daunting bridges, and endless beauty – that’s how I would describe my first experience with glacier fieldwork. I, Silje Waa ...[Read More]
