Harald Strauss

Harald Strauss is a Professor in the Faculty of Geosciences at the University of Münster, Germany, with over 235 publications and an h-index of 59. His research focuses on isotope geochemistry applied to marine sedimentary systems, hydrothermal environments, and early Earth processes. Current affiliations include active collaborations with research teams in Spain (Central Iberian Zone), South China Sea methane seep studies, and Oman Drilling Project investigations.

Professor Strauss's research interests center on biogeochemical cycling, particularly sulfur and iron isotope systematics in modern and ancient environments. His work examines methane seep systems, hydrothermal vents, and Archean-Eoarchean geological records to understand Earth's evolution. Key methodologies include SIMS analysis of authigenic minerals, multi-isotope systematics, and experimental approaches to quantify environmental effects like sea spray on isotopic signatures.

Analysis of his 15 most recent publications reveals consistent focus on isotope geochemistry applied to paleoenvironmental reconstruction, with strong emphasis on sulfur cycling in diverse settings from modern hydrothermal systems to ancient sedimentary records. His work bridges field observations, laboratory analysis, and experimental approaches to address fundamental questions in Earth system evolution.

Scientific contributions include:

• Pioneering work on sulfur isotope patterns in ancient seep environments
• Insights into Eoarchean mantle processes through sulfur isotope evidence
• Quantification of sea spray effects on coastal isotope systems
• Development of pyrite trace element proxies for magmatic volatile influx
• Advancements in understanding hydrothermal sulfur cycling in arc/back-arc systems

Professor Strauss maintains an active research program with regular fieldwork in diverse geological settings and supervision of collaborative projects. His laboratory group employs advanced geochemical techniques to investigate Earth's biogeochemical cycles across geological time, with particular strength in integrating multiple isotope systems for paleoenvironmental reconstruction. Current projects include studies of Ediacaran-Cambrian transition records and modern analog systems for early Earth processes.
