Steven R. Emerson has been a professor of Oceanography at the University of Washington for about 40 years. He taught Chemical Oceanography for most of this period while being the major advisor to 12 Ph.D. students and an equal number of post-docs. His research focuses on fluxes at the air-sea interface and the sediment-ocean interface. He is a fellow of the American Geophysical Union and the Geochemical Society.
Roberta C. Hamme is an associate professor in the School of Earth and Ocean Sciences at the University of Victoria, and holds a Canada Research Chair in Ocean Carbon Dynamics. She has taught upper-level undergraduate Chemical Oceanography since 2007. Her research focuses on understanding and quantifying the natural mechanisms that transport carbon from the surface ocean to the deep. Her main tools are measurements of dissolved gases, both bioactive gases such as oxygen and inert gases such as neon, argon, and krypton.
