New TCD paper: Dark ice on Greenland Ice Sheet

Our new discussion paper, led by Black and Bloom PDRA Andrew Tedstone, examines in detail why there is a stripe of dark, fast-melting ice on the Greenland Ice Sheet, particularly in the south-west. This 'dark zone' is clearly visible in satellite imagery of the Greenland Ice Sheet and is important because darker ice melts faster. … Continue reading New TCD paper: Dark ice on Greenland Ice Sheet

Challenges in quantifying ‘bioalbedo’

On Wednesday last week I traveled to the University of Bristol to give a seminar at the Centre for Glaciology. I presented a new physical model for the spectral albedo of ice with algal growth, along with some field data from 2016. Preparing for the talk, discussions with fellow researchers and insightful questions in the … Continue reading Challenges in quantifying ‘bioalbedo’
