From method development to climate reconstruction - oxygen isotope analysis of biogenic silica from Lake El’gygytgyn, NE Siberia

Aims and objectives

The objectives were

Although ?18O records from ice-cores and foraminifera are among the most important paleoclimate records only eight laboratories world-wide (including AWI) are able to analyse the ?18O in biogenic silica which have never been compared. This shortage is mainly due to methodological aspects and challenges. Generally, the complexity of the analysis itself from preparation to instrumentation already complicates and even often inhibits the application of this valuable proxy. All of these questions need to be addressed to guarantee an improved analysis for gaining higher-resolution ?18O records with enhanced reliability.

Hence, additional objectives and aims of this thesis are:
