Gert de Lange

Prof. Dr. Gert de Lange is a Professor at Utrecht University's Department of Earth Sciences, specializing in Geochemistry within the Faculty of Geosciences. His research focuses on three Mediterranean-specific domains: (1) high-resolution paleoclimatology and paleoceanography across multiple timescales (0-1 million years), (2) biogeochemical processes in extreme environments like anoxic hypersaline lakes and mud volcanoes, and (3) geochemical characterization of deep-sourced geological materials such as gas hydrates and minerals.

• Primary Research Themes
  • Paleoclimate/paleoceanography proxy validation
  • Methane oxidation dynamics
  • Redox-controlled mineral formation
• Key Methodologies
  • Multi-proxy sediment analysis
  • Isotope geochemistry
  • Field studies in Mediterranean deep-sea and coastal zones

His recent publications (2024-2025) demonstrate expertise in barium geochemistry for environmental reconstruction, sapropel analysis for anoxia studies, and space telescope instrumentation development through collaborations on TES bolometers and SQUID multiplexers. Notable work includes studies of Mediterranean Outflow Water dynamics, Holocene hydroclimate variability, and microbial processes in organic-rich sediments.
