New Paper: Glacier algae accelerate melting of the Greenland Ice Sheet

This week our new paper on the melt-accelerating effects of glacier algae on the Greenland Ice Sheet was finally accepted for publication. This paper was an absolute epic to get through peer-review - I might post about that later - but for now I'll focus on the paper content. I'm really pleased to see this … Continue reading New Paper: Glacier algae accelerate melting of the Greenland Ice Sheet

AI Adventures in Azure: Ice Surface Classifiers

For this post I will introduce what I am actually trying to achieve with the AI for Earth grant and how it will help us to understand glacier and ice sheet dynamics in a warming world. The Earth is heating up - that's a problem for the parts of it made of ice. Over a … Continue reading AI Adventures in Azure: Ice Surface Classifiers

CASPA at EGU 2018

The EGU annual meeting in Vienna is one of the major events in the earth science calendar, where the latest ideas are aired and discussed and new collaborations forged. My talk this year was in the "Remote Sensing of the Cryosphere" session. Here's an overview: Albedo is a primary driver of snow melt. For clean … Continue reading CASPA at EGU 2018

Frontiers Paper: Albedo products from drones

A new paper, led by Johnny Ryan, shows that a consumer grade digital camera mounted to a drone can be used to estimate the albedo of ice surfaces with an accuracy of +/- 5%. This is important because albedo measurements are fundamental to predicting melt, but satellite albedo data is limited in its spatial and … Continue reading Frontiers Paper: Albedo products from drones

Bioalbedo: new model and TCD paper

I'm very pleased to report our new paper is now in open discussion in The Cryosphere. The paper presents a new model for predicting the spectral bioalbedo of snow and ice, which confirms that ice algae on ice surfaces can change its colour and by doing so enhance its melt rate ("bioalbedo"). We also used … Continue reading Bioalbedo: new model and TCD paper

Diverse microbial habitats on the GRIS

We are now well┬áinto planning 2017 field work so I┬árevisited some archive footage from previous trips. The short clip below provides a good summary of the great diversity of microbial habitats that exist, even within a very small area of ice. These include cryoconite holes, a cryo-pond (the big cryoconite and water filled pool), algal … Continue reading Diverse microbial habitats on the GRIS
