PhD Opportunities in Geochemistry in Luxembourg

[Competition-funded dual award scheme; applicants are instructed to enter “Dual award funding” in the application form. The advert notes that not all advertised projects will necessarily offer a place on the programme.] This PhD project explores mineral–fluid–rock interactions in subsurface geological formations and how these coupled processes shape the performance and integrity of technologies central to the energy transition. The research is set against applications such as geothermal energy e...

The University of Cologne’s Institute of Geography is offering an interdisciplinary PhD project on the Rhine floodplain as a biogeochemically coupled system under stress. The project examines how altered hydrology shapes floodplain sediment dynamics and the wider ecosystem response, linking physical and geochemical processes with biodiversity, food webs, microbial activity, and greenhouse gas emissions. The doctoral researcher will contribute to a collaborative project with other PhD students an...

This funded PhD project investigates what happens on land when temperatures exceed 1.5°C and examines the long-term consequences of climate “overshoot.” The research will combine geochemical datasets with climate model simulations to determine how land systems respond to past, present and future warming. By connecting evidence from different climate periods with modelled future conditions, the project will contribute to improved assessments of the environmental consequences of exceeding 1.5°C of...

This PhD project at Delft University of Technology focuses on extracting new mineral-exploration value from legacy geophysical datasets originally acquired for petroleum work. You will investigate the thin Kupferschiefer horizon beneath the Netherlands and the North Sea, combining well logs, seismic reflection data, basin analysis, geochemistry and mineralogical information to characterise the target and its mineral potential. The research is strongly interdisciplinary and sits at the intersecti...

This fully funded PhD project investigates how human impacts affect the growth of juvenile fishes during their first summer in dynamic, wave-swept sandy beach environments. The research will combine laboratory trials at Brixham Laboratory with extensive field sampling on beaches in Devon and Cornwall. The project will bring together biochemical, physiological and geochemical techniques to examine how warmer temperatures and high levels of beach visitation influence fish growth and the functionin...

Linnaeus University is recruiting a motivated PhD student for research on the impacts of glacial meltwater on biogeochemical cycling in northern Greenland’s fjords. The project will investigate how glacial meltwater influences the transport and transformation of iron, manganese, phosphorus, and organic carbon within Arctic fjord environments. The research sits at the intersection of environmental geochemistry , Arctic research , and biogeochemistry , with a focus on understanding chemical proces...

This PhD project in environmental science focuses on environmental geochemistry in Arctic fjord-shelf systems , with Greenland’s northern coast as the central study area. The project addresses how rapidly increasing meltwater from the Greenland Ice Sheet influences the transport, transformation, and interaction of iron (Fe), manganese (Mn), phosphorus (P), and carbon (C) in downstream marine environments. The doctoral student will work with an extensive sample set collected during the GEOEO Nort...

This PhD Research Fellow position in marine geomicrobiology is based at the Department of Earth Science , University of Bergen , and is linked to the Centre for Deep Sea Research and the Geochemistry and Geobiology research group. The project addresses how rapid Arctic Ocean change affects the carbon flux from surface waters to the seafloor, and how that shift influences the microorganisms living in Arctic sediments. The successful candidate will investigate the short- and long-term effects of v...

The University of Göttingen offers a doctoral programme in Geoscience built around three major research foci in the faculty. The programme explores coupled processes across the geosphere, hydrosphere, atmosphere, and biosphere, with attention to geological, mineralogical, crystallographic, and biological processes involved in mineral and rock formation. It also covers the dynamics and transport processes of the lithosphere, including the physical and chemical evolution of melts in magma reservoi...
