We all foot the bill for a warmer Arctic

This week Open Access Government published the third in a series of articles I have written about Arctic science. The first showed why it is critical to understand the past, present and future of the Arctic; the second examined AI and machine learning and their potential to help us to understand and predict Arctic change, … Continue reading We all foot the bill for a warmer Arctic

Managing & Publishing Research Code

Several journals now request data and/or code to be made openly available in a permanent repository accessible via a digital object identifier (doi), which is - in my opinion - generally a really good thing. However, there are associated challenges. First, because the expectation that code and data are made openly available is quite new … Continue reading Managing & Publishing Research Code

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

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

NEP Video

Here is a quick video I made outlining the well-known "total dissolved inorganic carbon" (TDIC) procedure for measuring Net Ecosystem Productivity.  It is a very basic aide-memoir for undergraduate and postgraduate students showing the major steps in the TDIC procedure. There is a paper document to accompany this video available to students working in the labs at the … Continue reading NEP Video

New Scientist’s “Icy Oases” Article: The full interviews!

New scientist recently published an article introducing cryoconite holes as oases for microbial life on ice surfaces. As 'new scientists' working on cryoconite, colleagues Arwyn Edwards (Aberystwyth University), Karen Cameron (GEUS / Dark Snow Project) and I were interviewed by science writer Nick Kennedy. Of course only a few sound-bites made it into the final … Continue reading New Scientist’s “Icy Oases” Article: The full interviews!

Water Bears on Ice: Guest blog by Jesamine Bartlett

Huge thanks to Jesamine Bartlett - a recent MSc graduate from the University of Sheffield who has been working on Tardigrade research - for providing this introduction to the weird world of water bears... Whether or not you like microbiology, bugs, or even science, no one can deny the frankly awesome nature of the Tardigrade. … Continue reading Water Bears on Ice: Guest blog by Jesamine Bartlett

Living the High Life… in the aeolian biome

At the top of the highest mountains - where air is thin, solar irradiance intense, meteorology unpredictable, temperatures low and food scarce - spiders live on snow. The same spiders that are found in much more favourable conditions at sea level around the world. With no specific adaptations and no obvious lower trophic levels to … Continue reading Living the High Life… in the aeolian biome

Measuring NEP

Some under- and post-grad students recently asked me to explain how to measure NEP in cryoconite holes, and this post represents a brief overview on their behalf - apologies to other readers who may find this a bit "niche" - something more accessible next time! What is NEP? NEP stands for Net Ecosystem Productivity and is a … Continue reading Measuring NEP

Carbon Flux Modelling

C Flux Modelling To date, three attempts have been made to model carbon (C) fluxes in the supraglacial environment, all in the past five years. These models tried to reconcile 'snapshot' measurements of net ecosystem productivity (relative rates of photosynthesis and respiration - NEP) made at a small number of sites with atmospheric carbon fluxes … Continue reading Carbon Flux Modelling
