Postdoctoral position: Rock weathering experiments with microbial ecosystems under Archean conditions Université Côte d'Azur in France

PhD fellowship in marine geomicrobiology at the University of Bergen , Department of Geosciences, linked to the Center for Deep Sea Research and the research group Geochemistry and Geobiology. The project focuses on how global warming and changing Arctic Ocean conditions affect carbon fluxes, microbial activity, and microbial diversity in Arctic sediments . The successful candidate will develop in-situ experimental setups and combine geochemical measurements with molecular microbiological method...

Two PhD opportunities are available at the University of Granada (UGR), Spain within the CARBONATE project: Carbonate Biosignatures and Origins in Natural Terrestrial Environments . The projects sit at the intersection of geomicrobiology , geochemistry , biomineralization , carbonate and evaporite mineralogy , and extreme environments . Research directions may include microbe–mineral interactions, gypsum-rich and hypersaline systems, experimental mineral formation, microscopy and spectroscopic c...

Postdoc opportunity at Utrecht University in ocean acidification and the marine phosphorus cycle. The project, PHOSFLUX, is an NWO-funded collaboration between Utrecht University and NIOZ that investigates how ocean acidification may alter CaCO3 fluxes, phosphorus cycling, ocean fertility, and CO2 uptake. The postdoctoral researcher will focus on biogeochemical modelling and develop a reactive-transport model for phosphorus dynamics in sinking and deposited marine snow. The work includes process...

Fully funded PhD opportunity in Toulouse, France, under the MSCA COFUND BEST programme. The project focuses on Sahara dust in the Pyrenees, using peat records and current monitoring services to reconstruct Saharan dust input over Spain and France. The research combines peat archives, atmospheric collectors, trace-metal geochemistry, and isotope geochemistry, making it a strong fit for students interested in Environmental Science, Earth Science, Geology, and Chemistry. The PhD will be hosted in T...
