Warren L. PrellHenry L. Doherty Professor Emeritus of Oceanography, Professor of Earth, Environmental, and Planetary Sciences (Research)
I received a BA in 1966 with Honors from Hanover College, and a PhD in 1974 from Columbia University. I became director of oceanographic and geologic programs for the NYC Energy Research and Development Authority before being appointed as Assistant Professor in the Department of Geological Sciences at Brown in 1975. I was promoted to full professor in 1989, and was appointed to the Henry L. Doherty Chair in Oceanography in 1990.

I research global-scale paleoceanography and local-scale estuarine oceanography. I am interested in the paleoceanographic evolution of the Cenozoic climate-ocean system and the interaction between global tectonic and orbital forcing on the evolution of climate. I study changes on the modern annual cycle and on geologic time scales. My estuarine oceanography research is on distribution and causes of low dissolved oxygen in Narragansett Bay.
My research seeks to understand the evolution of the Cenozoic climate-ocean system and especially the evolution of the Indian-Asian monsoon system and how it is forced by interaction between regional tectonic changes, orbital forcing, and inter-hemisphere ocean feedbacks. A major thrust in my ongoing collaborative grant with Z. Liu (U. of Wisconsin) is the generation of time dependant GCM simulations of past climate that enable us to directly compare paleoceanographic timeseries to climate model results. This collaboration has already yielded several publications.
My estuarine oceanography research seeks to understand the dynamics of carbon and nitrogen cycling in Narragansett Bay as related to the recent and past environmental history of the Bay. Our NOAA CHRP grant and Brown seed money support have produced exciting results, which were presented at the Estuarine Research Foundation 19th Biennial Conference in Providence in fall 2008. Topics included the Episodic Summer-Time Hypoxia in Narragansett Bay (Narragansett Bay CHRP) (Prell WL, Murray DW, Orchardo JM, Deacutis C, Saarman E), Grain Size Patterns and Elemental Composition of Surface Sediments from Narragansett Bay (Murray, D.W., Rincon, C.E., and Prell, W.L), and Benthic foraminifers as proxies for the spatial and temporal extent of hypoxia (Narragansett Bay CHRP) (Martin, April H, Prell, Warren L, Murray, David, Heggie, Keira). These initial studies have set the foundation for new proposals on eutrophication and environmental history of the Bay. To help develop the critical mass of researchers here at Brown, I have worked closely with Jeremy Rich, a new appointment in CES, to develop the seed money proposal "Developing an Interdisciplinary Research Team: Narragansett Bay as a Model System". The past year's research has generated the data for several publications, which are in preparation. The dynamics of carbon/Nitrogen cycling related to estuarine processes is a hot topic and one that Brown researchers can carve out a niche.
