Research Interests

Dr. Beaupré’s research constrains the ocean’s role in Earth’s climate system by examining the marine component of the global carbon cycle. Specifically, he investigates the provenance and reactivity of organic carbon in the sea by coupling radiocarbon dating with chemical analyses. His work has appeared in Nature Geoscience, Geophysical Research Letters, Nuclear Instruments and Methods in Physics Research, and Fusion: Journal of the American Scientific Glassblowers Society, and he has contributed several textbook chapters on carbon isotopes in the sea.

Isotope (14C, 13C) biogeochemistry of marine dissolved and particulate organic matter (DOM, POM), dissolved inorganic carbon (DIC), marine sediments, and terrestrial soils; Global distribution of DO14C

Isotope reaction analyses (photochemical, thermal, acid/base mineralization) and rapid characterization of complex mixtures (DOM, POM, sediments) with coarse chemical, isotopic, and kinetics spectra

Instrumental and methodological development; Continuous Flow 14C Accelerator Mass Spectrometry
