William M. Berelson’s research involves studies of biogenic material fluxes to the sea floor and across this boundary. Capturing fluxes through the water column involves the use of sediment traps and measurements of water column profiles (solutes and suspended particles) and modeling; fluxes across the sea floor involves the use of benthic chambers and pore water diagenetic models. Analysis of the solid phase helps link oceanographic biogeochemistry with the sedimentary rock record. Fluxes and reactions involving O, C, N, P, CaCO3, bSi, Fe and S (and their isotopes) are among those that he works on.
Most of his students have an opportunity to join an oceanographic research cruise and/or participate in various forms of field research. Recent field study areas include: Eastern Tropical North and South Pacific Ocean; Western Tropical North Atlantic Ocean within the Amazon River plume; Eastern North Pacific (between Hawaii and Alaska); Gulf of Mexico zone of hypoxia; San Pedro/Santa Monica Basin OMZ; Yellowstone National Park Hot Springs; Mono Lake, CA; Monterey Formation, CA; Green River Formation, WY and the T-J boundary rocks (Pucara Group) in central Peru.
He is affiliated with many groups at USC, including the Geobiology, Geochemistry and Climate programs in the Department of Earth Sciences and the Marine and Environmental Biology Section of the Department of Biological Sciences; the Molecular and Computational Biology Section of the Department of Biological Sciences; and is faculty appointed in the Environmental Studies Program. He also is affiliated with the USC Wrigley Institute for Environmental Studies.
He is part of an interdisciplinary USC team leading the USC Urban Trees Initiative, partnering with the City of Los Angeles to develop an urban forest of shade trees in the community surrounding the USC Health Sciences campus. In this project he leads an effort to define how trees accumulate pollutants, how much, which trees etc. He also leads the Carbon Census group, a program to study hyperlocal distributions of CO2 and other air constituents in Los Angeles neighborhoods.
Berelson received the USC Dornsife College Raubenheimer Award in 2018, recognizing outstanding performance in teaching, scholarship and service within the university.
