Postdoctoral Researcher in Stable-Isotope Nitrogen Ecology and Orbitrap Isotopologue Analysis Netherlands Institute of Ecology (NIOO-KNAW) in Netherlands

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...

Oak Ridge National Laboratory (ORNL) is recruiting a Postdoctoral Research Associate in Plant-Soil Interactions and Coastal Biogeochemistry within the Environmental Sciences Division. The project is part of the interdisciplinary Exploring Gulf Region Ecosystem Transitions (EGRET) collaboration, which studies disturbance-driven ecosystem transitions across the U.S. Gulf Coast using field observations, laboratory mesocosms, AI/ML, remote sensing, process-based modeling, and advanced analytical tec...

PhD position at the University of Amsterdam in deep-sea benthic ecology in the Arctic Ocean . The project is part of C-CONNECT (“Plumbing the biological pump: Linking missing carbon flows between pelagic and benthic ecosystems in a changing Arctic Ocean”) and focuses on how deep-sea life, benthic faunal communities, and carbon cycling interact under rapid Arctic climate change. You will work in an international team involving the University of Amsterdam, Naturalis Biodiversity Center , NIOZ Roya...

PhD opportunity in Environmental Analytical Chemistry at the University of Stuttgart , within the Research Facility for Subsurface Remediation (VEGAS-IWS) . The project is part of the DFG-funded IRIS-PFAS initiative and focuses on PFAS , stable isotopes , Orbitrap mass spectrometry , and environmental forensics . The successful candidate will develop novel Orbitrap-based stable isotope methods for PFAS source identification. This is a research-intensive position at the interface of analytical ch...

Wageningen University & Research is advertising a fully funded PhD on moss traits, bryophytes, fire ignitability, peatland, tundra, and vegetation-climate feedbacks . The project asks how moss functional traits influence fire ignition and fire dynamics in high-latitude ecosystems , including boreal peatlands and tundra, where warming, permafrost thaw, and increasing fire frequency are reshaping carbon storage and ecosystem functioning. The PhD is embedded in the Plant Ecology and Nature Conserva...
