ISOPERM
Welcome to the ISOPERM — a new, multidisciplinary, collaborative research project investigating the stability of permafrost in Siberia throughout the last ca. 2 million years.
Siberian permafrost is a major carbon store, containing double the amount of carbon found in today’s atmosphere. Anthropogenic global warming threatens the stability of this ancient permafrost, with the potential to release vast amounts of greenhouse gases into the atmosphere, further exacerbating climate change.
This project aims at the reconstruction of past continental temperatures, seasonal characteristics, and historical permafrost extent, thus establishing critical thresholds for Siberian permafrost formation and thaw that can inform predictions of permafrost dynamics in the near future.
Collaborators
ISOPERM is a collaboration between the Department of Geography and Environmental Sciences at Northumbria University, United Kingdom, and the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research in Potsdam, Germany. We work closely with colleagues at The Technical University of Irkutsk and the Arabika Speleoclub in Russia, the LARA Lab at the University of Bern, the Helmholtz-Zentrum Dresden-Rossendorf in Germany, the University of Oxford in the UK, and the Israelian Geological Survey.
This project is funded by The Leverhulme Trust.

Funded PhD Position available
8 December 2022
Are you enthusiastic about environmental science and climate change?
We’ve got a fully funded PhD place available from summer 2023 to look at glacial-interglacial changes in the permafrost region of Mongolia. Find out more here.
Welcoming our new Intern, Marley Cleghorn
6 December 2022
We’re delighted to be joined by Marley Cleghorn for the next ten weeks. Marley will be helping us process ostracod samples for clumped isotope analysis.
Marley is an undergraduate student here at Northumbria. Check out his profile on our team page.
Dispatches from the field
We spent a month in Siberia collecting speleothem samples throughout February 2022. Check out our travel blog and explore what it’s like doing fieldwork in some of the coldest regions on Earth.
