PostDoc Marine Geochemistry - Cosmogenic Radionuclides

Embedded in the newly established research group "CLOC" (Cosmic Links between Ice Cores and Sediments) we seek a communicative and ambitious postdoctoral reseacher (f/m/d) with expertise in marine geochemistry and an interest in geochronology and cosmogenic radionuclides.

The group is part of the marine geochemistry section at AWI and explores the use of 10Be and 26Al as tools to synchronize different marine sediment records as well as ice cores. The announced position will focus on investigating the controls on 26Al concentrations in marine sediments, characterizing the role of changes in the cosmic ray flux and the geochemistry of aluminum.

Tasks

• The core of this position is to investigate the controls on cosmogenic 26Al concentrations in marine sediments.
• The focus will be on isolating the impact of changes in the cosmic ray flux on 26Al deposition. Ultimately, the goal is to apply this signature to date and synchronize marine sediment records.
• This will involve modifying and testing sediment leaching protocols, measuring stable and cosmogenic Aluminum and Beryllium isotopes on globally distributed surface samples, as well as creating long time-series on suitable sediment cores.
• The project will contribute to improving our ability to date marine sediments at high precision and allow an improved understanding of paleoclimate dynamics
• The results will be published in peer reviewed scientific journals and presented at international conferences
• In addition, there will be the opportunity to participate in the supervision of PhD and undergraduate projects

Requirements

• PhD in Environmental Sciences, Geology, (Geo-)Chemistry, Physics, or similar
• Track record of publishing in peer-reviewed journals and presenting at conferences
• Strong background in marine geochemistry
• Experience in working in a wet-chemistry laboratory
• Background in cosmogenic radionuclides and/or trace element/isotope analysis is a strong advantage
• Experience in chromatographic methods is an advantage
• Research independence and experience with interdisciplinary research will be highly ranked
