Eawag, the Swiss Federal Institute of Aquatic Science and Technology, is an internationally networked aquatic research institute within the ETH Domain (Swiss Federal Institutes of Technology). Eawag conducts research, education and expert consulting to achieve the dual goals of meeting direct human needs for water and maintaining the function and integrity of aquatic ecosystems.
The Department of Surface Waters - Research and Management (SURF) has a vacancy for a
Postdoctoral Researcher in organic geochemistry
The one-year position will investigate the presence of long chain alkenones, temperature-sensitive lipids produced by haptophyte algae, in Swiss Lake sediments.

Project summary:
Alkenones are ubiquitous in marine environments, where they have been used for decades to reconstruct quantitative changes in sea-surface temperatures. Increased reporting of alkenones in both saline and freshwater lakes worldwide suggests that there is great potential for alkenone-based paleotemperature reconstructions in lacustrine settings. Past temperature records are important tools for inferring climate dynamics over time and provide empirical data for testing climate models that improve our understanding of natural climate variability. Unfortunately, very few quantitative records of pre-historic temperatures exist in Switzerland, particularly records that reflect changes during the cold season. This project aims to conduct a survey of Swiss Lakes for the presence of alkenones, and if present, to test which environmental constraints control the presence of alkenones and the distribution of different alkenone producers. The laboratory work will include lipid extraction, purification and quantification on a GC-FID, as well as genomic analyses if alkenones are detected, to determine which alkenone-producing phylotypes are present.

The position is for a fixed term of one year. Applicants should have an earned doctorate in a relevant field of geosciences, environmental sciences, chemistry or a related field. Fluency in English is mandatory, while a background in organic geochemistry and fieldwork experience is an additional asset.
