Topic description
L'Arctique se réchauffe rapidement, provoquant le dégel du pergélisol et la libération de grandes quantités d'azote, de carbone et de gaz réactifs tels que les composés organiques volatils (COV) et les oxydes d'azote (NOy) dans l'atmosphère. Ces émissions peuvent modifier la chimie atmosphérique, contribuer au changement climatique et influencer la formation d'aérosols, mais la compréhension actuelle reste limitée, notamment dans les régions reculées. Ce projet vise à étudier les mécanismes des émissions gazeuses réactives du pergélisol, en se concentrant sur l'activité microbienne et le couplage des émissions de COV et de NOy. La recherche comprendra des expériences en laboratoire, le développement de méthodes analytiques, des mesures de flux chimiques, des études mécanistiques et éventuellement de la modélisation. Le/la candidat(e) travaillera sur des échantillons de sol réels et utilisera des instruments analytiques avancés tels que la spectrométrie de masse haute résolution, la chimiluminescence et l'absorption UV-Vis.

The Arctic is warming rapidly, causing permafrost thaw and the release of large amounts of nitrogen, carbon, and reactive gases like volatile organic compounds (VOCs) and nitrogen oxides (NOy) into the atmosphere. These emissions can alter atmospheric chemistry, contribute to climate change, and affect aerosol formation, but current understanding is limited, especially in remote regions. This project aims to investigate the mechanisms behind reactive gas emissions from permafrost, focusing on microbial activity and the coupling of VOC and NOy emissions. The research involves laboratory experiments, analytical method development, chemical flux measurements, mechanistic studies, and possibly modeling. The candidate will work with real soil samples and advanced analytical instruments such as high-resolution mass spectrometry, chemiluminescence, and UV-Vis absorption.
