The melting Polar Ice caps and receding glaciers worldwide are resulting in the emergence of microorganisms entombed in the ice for considerable periods of time. A famous example is the frozen graves of the 1918 pandemic Spanish flu victims on Svalbard, perhaps the best known natural reservoir of this deadly virus, which killed over a third of the world’s population. As ice-encased material slowly melts, microorganisms will be released that may have either beneficial or harmful effects on both the environment and the human population. Recently, we have been studying the types of microorganisms that are likely to emerge from this secretive gene pool (Figure 1a) and are looking at ways to both harness their potential and mitigate any potential threat; however, most of the expanse of this remote frozen region remains largely unexplored.
This work will focus on Svalbard, an archipelago in the Arctic Ocean (Figure 1b). In this project, we would investigate the dynamics of the melting cryosphere from a microbiological perspective. It would help determine which species may have already emerged and which ones are likely to emerge from the ice, assess their potential impact on the present biosphere, examine how they have adapted to survive in such extremes and determine which potential refugia might have enabled them to survive and re-emerge from such extended periods of freezing. The project will develop skills in microbiology, molecular ecology, bioinformatics, biogeography, polar fieldwork and life in extreme environments. It will form part of the microbial ecology group at Northumbria University and contribute to an international network investigating long distance aerobiological transfer and its potential relationship with human health.
The project will require fieldwork in the Arctic, for which funding can be provided.
