Roberta Hamme

Roberta Hamme is a Professor and Graduate Advisor in the Department of Earth and Ocean Sciences at the University of Victoria's Faculty of Science. She holds a BA from Pomona College and MSc/PhD from the University of Washington. Her research focuses on chemical oceanography, dissolved gases, ocean carbon cycling, and marine productivity using advanced techniques like mass spectrometry and BGC-Argo floats.

Her research investigates fundamental ocean processes including air-sea gas exchange, water mass formation, denitrification, and ocean carbon sequestration. She employs geochemical tracers and autonomous platforms to understand biogeochemical cycles in diverse environments from the subarctic Pacific to Arctic regions.

Analysis of Dr. Hamme's recent publications reveals consistent focus on ocean deoxygenation, carbon flux quantification, and climate impacts on marine systems. Her work utilizes innovative approaches including neural networks for CO2 estimation, noble gas tracers for ventilation studies, and integrated ship-autonomous observation systems. Research spans from coastal zones to open ocean, addressing pressing climate-related changes in ocean chemistry.
