SIOS-funded autumn fieldwork in Svalbard

11/10/2021

0 Comments

 
James is in Ny-Ålesund, Svalbard, carrying out fieldwork supported by the SIOS Access Program (CAP-BIO, SIOS-2019-0011). Our aim is to sample proglacial soils during the autumn freeze-up period as the last rays of sunshine disappear before the long Polar night, and carry out essential maintenance on the sensor equipment we installed during the summer. 

The onset of autumn freeze-up limits biological activity because temperatures fall below zero, and liquid water becomes scarce. However, recent studies have shown that biological activity may persist year-round, despite the harsh environment. Nevertheless, the seasonal dynamics of Arctic soil ecosystems are barely beginning to be explored, in part because of logistical challenges associated with accessing field sites during the permanently dark period. 

The results of the project will contribute to understanding the future of Arctic soils exposed by glacier retreat, and the role the long polar night plays in that future. 

​The CAP-BIO field team consists of James Bradley (QMUL, GFZ), Mihai Cimpoiasu and Harry Harrison (BGS), Lara Vimercati (CU Boulder).

Congratulations to PhD student Amy Solman who was successful in her funding application to the QMUL Postgraduate Research Fund to support her carrying out  transcriptomics work in Lyon, France, in early 2022. Amy will spend several weeks in the lab of Catherine Larose at École Centrale de Lyon to extract and sequence RNA from her snow, ice and cryoconite samples collected in Svalbard earlier this year.

We are delighted to welcome Dr. Zhou Lyu to the lab! Zhou is biogeochemical modeller  with expertise in terrestrial ecosystem biogeochemistry modelling, focussing on carbon dynamics and climate change. She is currently working on Arctic soil microbial and biogeochemical modelling as part of NERC & NSF-funded SUN SPEARS project. She earned her B.Eng. from Wuhan University, her MS and PhD in Earth Sciences from Purdue University, and completed a postdoc at Lawrence Berkeley National Lab. Welcome Zhou!

SUN SPEARS fieldwork in Svalbard

8/2/2021

0 Comments

 
​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.

Margaret receives Earth and Space Award

7/5/2021

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.

New paper 'How allogenic factors affect succession in glacier forefields' in Earth Science Reviews

5/17/2021

0 Comments

 
'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).
