PhD Position: Examining the Thresholds in Past Atlantic Ocean Circulation Using Stalagmite Geochemistry

100%, Zurich, fixed-term

If you are intrigued by the study of past climate, enjoy working hands-on with samples in the lab, and generating new geochemical data, this PhD project may be an ideal fit for you. The Atlantic Meridional Overturning Circulation (AMOC) is a crucial component of global heat transport that significantly influences both European and global climate. It has weakened abruptly numerous times over the past several hundred thousand years and has subsequently recovered within centuries to millennia. This PhD position will enhance our ongoing research aimed at diagnosing the causes of these abrupt weakenings and understanding the factors that allowed AMOC to recover. The project involves generating new geochemical records from stalagmites found in coastal caves to reconstruct the timing of changes in North Atlantic salinity in relation to AMOC variations. We will interpret these records using process models and tracers in atmosphere-ocean general circulation experiments.

Job Description

• As a PhD student, you will plan, generate, and interpret new research data. You will present your findings to scientific colleagues in workshops and conferences and prepare your research for publication in scientific journals.
• You will collaborate with a research team at ETH and other institutions.
• Your research will require international travel for research stays focused on U/Th dating of stalagmites and training in model-data comparisons.
• You will enhance your skills by taking required courses (12KP) in disciplinary and transversal skills.
• Additionally, all PhD students are expected to dedicate up to 10% of their employment time to departmental service, typically by contributing to teaching activities, which also helps build communication and management skills.

Profile

• A Master's Degree relevant to paleoclimate studies (e.g., Earth Science, or Atmosphere and Climate studies in Physics or Geography).
• Prior coursework in paleoclimate.
• Research experience in geochemistry laboratory analysis, including generating isotopic or trace element data.
• Strong quantitative skills, comfort with coding, and good analytical thinking.
• A commitment to working in an interdisciplinary team that combines climate modeling, geochemical process models, and new geochemical data.
• Strong skills and a commitment to growth in academic writing.

Workplace

ETH Zurich offers a thriving environment for research and collaboration. As a PhD student, you will be part of a dynamic team, enhancing both your professional and personal development.
