Research Interests
His research explores the intersection of isotope geochemistry and climate science, particularly through the development of analytical techniques like femtosecond laser ablation for boron isotope analysis in marine carbonates. He investigates paleo-pH reconstruction in corals, isotopic fractionation in alkenones, and carbon cycling in peat bogs. His work bridges analytical chemistry, marine ecology, and paleoclimate modeling.

Publication Trends
His publications span 2023–2008, emphasizing isotopic analysis (δ11B, δ13C), paleoceanographic proxies, and climate dynamics. Key subfields include alkenone-pCO2 methods, coral-based reconstructions, and sediment geochemistry.

Collaborative Networks
Dr. Benthien frequently collaborates with institutions like the European Association of Geochemistry and co-authors such as G. Steinhoefel, J. Bijma, and M. T. J. Van der Meer on projects involving mass spectrometry, paleo-pH studies, and carbon cycling.
