James has been promoted to Senior Lecturer in Environmental Science. Thanks go out to great colleagues everywhere for fantastic mentoring, exciting collaborations, past and ongoing projects, and early career researchers, especially in the lab group. Lot's of exciting work ahead!
James is in Ny-Ålesund, Svalbard, for the first field campaign of the NSF and NERC-funded SUN SPEARS project, investigating seasonal changes in microbial communities in Arctic soils. Accelerated climate warming in the Arctic is causing significant reductions in the extent of glaciers and ice sheets. As glaciers retreat, pioneer soils are uncovered, supporting emerging microbial communities which drive biogeochemical transformations. The SUN SPEARS project will characterize the year-round soil biological, thermal and hydrological properties, to better understand the fate of emerging Arctic soils and develop continuous models of soil biogeochemical dynamics. The multi-disciplinary team are busy collecting the first sets of biological and chemical samples from Midtre Lovénbreen, and are installing several monitoring stations which include arrays of geo-electrical sensors.
James convened the session '8f Understanding the co-evolution of Earth's interior, its surface, and its microorganisms' at Goldschmidt 2021 with Dominik Hülse and Emily Zakem. Highlights included a keynote talk from Stephanie Dutkiewicz on modelling ecology and biogeochemistry in the global ocean, and an invited talk from Rui Zhao on ammonia-oxidizing archaea in marine sediments.
Congratulations to Bradley Lab PhD student Margaret Cramm who has been awarded a grant from the Earth and Space Foundation for her project: "Dispersal of life from the deep biosphere to the cryosphere". The award provides funding towards a field trip to sample an Arctic hot spring, to test the hypothesis that thermophilic organisms capable of long-term dormancy are rising from the deep hot biosphere to the cold surface biosphere in geothermal fluids.
Congratulations to Margaret and Amy who each presented excellent posters at the 2021 NHM Student Conference in London!
'How allogenic factors affect succession in glacier forefields' published in Earth Science Reviews.
Here we critically review the use of chronosequence approaches in glacier forefields, showing strong effects of initial site conditions, geomorphic disturbances and biogeomorphological processes.
Congratulations to recent PhD-graduate Robin Wojcik on leading this effort, with contributions from James, Liane Benning (GFZ Potsdam) and Jana Eichel (Utrecht University).

James and Rey are in Ny-Ålesund, Svalbard, together with international collaborators Bartek Luks (IG PAS, Poland) and Catherine Larose (Laboratoire Ampère, Lyon, France) on the SIOS-funded project IN-SPACE. They are collecting samples from the Midtre Lovénbreen glacier catchment to look at how spring melting affects microbial community dynamics and biogeochemical cycles.
Bradley lab PhD student Margaret Cramm and supervisor James have been awarded a Center for Advanced Studies Short Term Fellowship to Ludwig-Maximilians-University of Munich (LMU) for their project 'How does permafrost thaw affect microbial activity and function in Arctic soil?'. Margaret and James will visit LMU as CAS Fellows, where they will be hosted by Professor Bill Orsi at the Department of Earth and Environmental Sciences. Margaret will carry out an extended secondment in Bill's lab at LMU to develop a combined genetic and stable isotope labelling approach for the analyses of active biological communities within Arctic permafrost under different warming regimes.
James, Amy and Rey are in Svalbard for fieldwork associated with the INTERACT-funded project AMBER-ICE. They are sampling surface snow and ice from Foxfonna glacier, and plan to analyze the samples to understand what kinds of ecosystems these environments support and how they are susceptible to seasonal changes and climate change. They are supported in the field by the Czech Arctic Research Station in Longyearbyen.
