The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government. AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics thus allowing multidisciplinary approaches to scientific goals.

PhD position for "Marine temperature variability of the last millenia and robustness of the proxy record" (m/f/d)

Background
Determining the magnitude of natural climate variability is necessary for predicting the plausible range of future climates and to test climate models. As the instrumental record is limited to ~ the last century, the analysis of proxy records of the Holocene is crucial in order to provide information about climate variations on decadal to millennial timescales.

However, current marine paleoclimate records are noisy and often lack the appropriate temporal resolution to reconstruct climate variations on society relevant timescales. Further, the correlation between existing records is often low, either pointing to highly noisy or unrepresentative records or to more localized climate variations than predicted by models.

This thesis will overcome this challenge by combining the Mass spectrometry imaging (MSI) technique that allows measuring temperature proxies at an unprecedented resolution in the Hinrichs Lab at MARUM and the methods and expertise of the ERC Starting Grant SPACE (Space Time Structure of Climate Change) team.

It will investigate the spatial and temporal variability of Holocene proxy records; develop new techniques to reduce the noise in MSI based temperature records and develop the first quantification of marine interannual to multi-centennial climate variability based on a single climate archive type.

The PhD thesis is part of the MARUM Cluster of Excellence: The Ocean Floor – Earth’s Unchartered Interface and the ERC Starting Grant SPACE (Space Time Structure of Climate Change)
