About the research project

Polar regions play a key role in the regulation of the global biogeochemical cycles and climate systems, and accelerated rates of change experienced in both the Arctic and Antarctic prompt urgent investigations into interactions between the ocean, cryosphere, atmosphere, and biosphere. Palaeoecological studies are particularly useful in this context, because they can provide information about long-term impacts of environmental change on the biosphere for ground truthing and constraining contemporary models of ecological change. This project will investigate both sedimentary ancient DNA (sedaDNA) and RNA (sedaRNA) from the Arctic and the Antarctic to investigate past ecosystem change and function. While sedaDNA have been increasingly used over the last few years, the application of sedaRNA techniques for the study of ecosystem function is completely novel and underexplored. Specifically, this project will focus on a) collection of new sediment material from the Arctic during IODP Exp. 403, b) extraction of ancient DNA and RNA from the newly collected Arctic as well as from existing Antarctic marine sediment cores, and c) place this data into an environmental context using geochemical proxies, such as the oxygen isotope records from the same sites. This research will provide novel insight into marine ecosystem adaptation to environmental change in two similar but spatially remote regions that are both extremely vulnerable to contemporary climate change.
