Antarctica 2020

On 30th December I left the UK to work in the southern hemisphere for the first time. As part of the MicroMelt project, the aim was to gather samples and measurements from a selection of glaciers on Livingston Island, to better understand and quantify the role of microscopic life on glaciers in transforming and accumulating … Continue reading Antarctica 2020

Svalbard UAV tests

Having made successful UAV test flights at home in the Peak District, we have relocated to Svalbard for a week to test the equipment in the most challenging possible conditions. We are flying in temperatures as low as -10 C, in gusty wind and after pulling the UAV to the field site in its flight … Continue reading Svalbard UAV tests

High bradfield: UAV test flights

The past few weeks have been spent working down in the robotics department at the University of Sheffield building a UAV (unmanned aerial vehicle, a.k.a drone). Ultimately, it will be used to make measurements of spectral reflectance of the ice surface in Greenland. It's been great fun working in robotics - entering the lab is like … Continue reading High bradfield: UAV test flights

Video: What Lives on Ice and Snow?

Here's a link to Krzysztof Zawierucha's (Adam Mickiewicz University, Poznan) new film about the biology of ice and snow, including cryoconite holes, snow and ice surfaces. The film clearly shows why Earth's ice and snow represents a threatened store of biodiversity and illustrates some of the feedbacks between physical and biological processes operating in the cryosphere. See also Krzysztof's paper in … Continue reading Video: What Lives on Ice and Snow?

Biocryomorphology

In a recent publication in Frontiers in Earth Science, Arwyn Edwards, Alun Hubbard and I outlined a framework for developing a more holistic understanding of the cryosphere. We suggest that the complex reciprocal relationships between physical and biological processes on ice surfaces represent a crucial gap in our knowledge of glacial systems, and propose to … Continue reading Biocryomorphology
