An important new publication with substantial input from CHARTER researchers has landed which is a pilot study on the reindeer impact on soil carbon storage which revealed that animal impacts are very different for permafrost and non-permafrost areas but that they facilitate more productive vegetation. Titled ‘Impacts of Reindeer on Soil Carbon Storage in the
Remote sensing specialist and CHARTER project researcher Annett Bartsch of bgeos and others have looked at developing a long-term monitoring system for rain-on-snow (ROS) events across the Arctic using satellite data. They explored the utility of different microwave frequencies from passive and active satellite sensors to detect wet snow and snow structure change during and
We are excited to let you know about an important new CHARTER publication which has just been released. Published in the journal The Cryosphere, the article is lead authored by Annett Bartsch, who is the leader of Work Package 1 is titled: Towards long-term records of rain-on-snow events across the Arctic from satellite data. The
A new CHARTER publication has just been published. Titled ‘The ecosystem effects of reindeer (Rangifer tarandus) in northern Fennoscandia: Past, present and future’, the paper is lead authored by Sari Stark and has input from multiple other CHARTER project researchers. Significant highlights include: From the abstract: The semi-domesticated nature of the reindeer (Rangifer tarandus L.) makes
Global warming is changing the Arctic by causing permafrost thaw, glacier melt, droughts, fires and changes in vegetation. These developments are strongly linked to the energy exchange between land and the atmosphere. Researchers at the University of Zurich have now shown that different plant communities in the tundra play a key role in this energy
Normally when one hears the term ‘artificial intelligence’, or deep neural networks, one might think of the technology giants and their ability to crunch immense amounts of data through our personal browsing habits so that they can build profiles of us in order to shill more content and product our way. But artificial intelligence (AI)
A new CHARTER publication has landed! Titled “Reindeer herding statistics in Russia: issues of reliability, interpretation, and political effect, the paper is authored by Kirill V. Istomin , Roza I. Laptander and Joachim Otto Habeck. The paper is published in the journal Pastoralism: Research, Policy and Practice. From the abstact: Official reindeer herding statistics are
An important new article with substantial CHARTER input has just been published in the journal Nature Communications. The article is titled New climate models reveal faster and larger increases in Arctic precipitation than previously projected. In other words, climate models are predicting that snowfall will be replaced by rain fall in the future, and this will occur at a faster rate than previous models suggested.

This phenomena is referred to as ‘Rain on Snow’ or ROS and it is something that is predicted to happen more often with potentially disastrous impacts on biodiversity in the Arctic. By way of example, tens of thousands of reindeer have died as a result of repeated ROS events in the Yamal peninsula and Finland in recent years, with potentially catastrophic consequences for reindeer herding peoples and cultures. The phenomona is also hazardous for other wildlife as rain refreezes and turns to ice, creating a physical barrier to pastures and nutrition. While ROS events are not unheard of, the frequency with which they are happening is.
An article has recently been published with substantial CHARTER researcher input. Published in the journal ‘Environmental Research Letters it is titled Arctic rain on snow events: bridging observations to understand environmental and livelihood impacts, the lead author is Marc Serreze of the National Snow and Ice Center, Uni of Colorado. CHARTER researchers involved include Julienne
CHARTER post-doc Andrew Martin (Andrew is in Work Package 4, see a video interview with him here) of the University of Oxford has recently published a paper in which he was the lead author (along with Work Package 4 leader Marc Macias-Fauria and CHARTER project leader Bruce Forbes, among others) in the journal, New Phytologist
