Missions
The recruited postdoctoral researcher will manage the new instruments measuring water isotopes in atmospheric vapor, deploying them at Concordia Station (Dome C, Antarctica) to obtain the first-ever winter measurements of water isotopes in Antarctica. They will combine these new isotopic measurements with weekly snow samples collected at Concordia Station to quantify post-deposition processes affecting the isotopic signals recorded in ice cores.
Activités
1) Deploy infrared spectroscopy instruments dedicated to the analysis of water isotopes in the Alps and Antarctica, along with the necessary peripherals for data analysis
2) Calibrate the data and analyze the results in order to understand post-deposition effects
3) Interpret the results and write scientific publications
Compétences
Knowledge:
• PhD (or expected to obtain it before starting the position) in a relevant field such as paleoclimatology, glaciology, infrared spectrometry, physics, or Earth sciences.
Skills:
• Hands-on laboratory experience in geochemistry or related measurement methods
• Strong experience in analytical and quantitative techniques, including infrared spectrometry for stable isotopes, atmospheric trace gas analysis, or related methods
• Proven ability to independently solve complex problems
• Experience in numerical data analysis (e.g., using Matlab or Python)
Interpersonal skills:
• Excellent written and oral communication skills in English
• Motivation to work effectively within a team
• Precision / reliability
Contexte de travail
The LSCE is a joint research unit (UMR 8212) between the French Alternative Energies and Atomic Energy Commission (CEA), the National Centre for Scientific Research (CNRS), and the University of Versailles Saint-Quentin (UVSQ), located at l'Orme des Merisiers. It is part of the Pierre Simon Laplace Institute (IPSL), a federation of nine climate and environmental research institutes in the Île-de-France region. LSCE comprises approximately 320 researchers, engineers, and administrative staff, including 150 permanent personnel from the three supervising institutions, and several dozen PhD students.
The selected candidate will work within the GLACIO team (Glaciers, Climate, and Stable Isotopes). The GLACIO team focuses on the study of climate and the hydrological cycle through the analysis of stable isotopes in water and atmospheric gases (nitrogen, oxygen, argon). Its main goal is to understand past (Quaternary) and present climate variability from tropical to polar regions in order to better characterize the coupling between climate and the atmospheric water cycle. The team includes around twenty members.
The position is part of the European project ERC SAMIR, and the candidate will work in close collaboration with Mathieu Casado (CNRS Researcher), Justin Chaillot (CEA Engineer), and the rest of the team.
