Introduction
I am a doctoral student focusing on Arctic sea-ice proxy development. I am using both biological and geochemical methods, as well as single cell PCR analysis to improve the knowledge we have on the species commonly associated with ice.

We recorded diatom species succession over one full year (May 2017–May 2018) using automated sediment traps installed in two contrasting Greenlandic fjords: the seasonally ice-covered Young Sound in high-arctic Northeast Greenland and the nearly sea-ice free Godthåbsfjord in subarctic Southwest Greenland. The traps were positioned at differing wate...

Sea-ice decline is one of the most striking consequences of recent climate-driven changes in the Arctic. The short observational time series and current climate models are inadequate in explaining the natural variation and foreseeing responses of arctic marine ecosystems, highlighting the urgent need to exploit natural archives (proxies). Protists abundantly stored in the seafloor of the Arctic Ocean are widely applied proxies for past sea-ice reconstruction, notwithstanding that little is known of their relationships to the ice ecosystem. This project will investigate seasonal processes that result in the formation of proxy archives and apply this knowledge in ecosystem modelling and reconstruction of pre-anthropogenic sea-ice conditions. The results will improve our understanding of the seasonal behaviour of arctic marine ecosystems in the long term.
