GEOLOGICAL SCIENCES AT BROWN UNIVERSITY
Wayland Collegium Faculty Seminar Series
Dear Colleagues, Faculty and Students:
Osvaldo Sala, Director of the Environmental Change Initiative, and I hope that the Wayland Seminars will enhance the interdisciplinary and intradepartmental research and education efforts (especially within the Environmental Change Initiative) that are directed toward understanding environmental processes on a variety of time and space scales. The Seminar is designed to acquaint Brown faculty and students in the life, physical and social sciences with the diversity of studies that use natural stable isotopic systems to identify and quantify the processes and history of environmental change and also to acquaint them with the current Environmental Isotope Lab facilities here at Brown.
We will be posting the schedule for Spring 2007 soon. Please visit this site again for more details.
We encourage all faculty and students to attend and participate in future seminar discussions.
We look forward to seeing you!

November 2006: "The coupled N and O isotopes of nitrate in the ocean" and "Polar ocean stratification during the last ice age: New data, physical mechanisms, and a deglacial hypothesis." Daniel M. Sigman, from Princeton University, studies the cycles of biologically important elements and their interaction with changing environmental conditions through the course of Earth history. His current research activities include the development of stable isotope methods by which to track the marine nitrogen cycle, today and in the past, and the construction of simple geochemical models for paleoceanographic and Earth history studies.
Carol is a distinguished stable isotope hydrologist from the US Geological Survey in Menlo Park, California. Carol has used stable isotopes as tracers in a wide variety of research areas, including hydrology, nutrient cycling, sources, and transport, and trophic levels in various ecosystems.
Coupling of Marine Nitrogen Biogeochemistry and Climate Change from Sediment N Isotopic Records. Mark is a Professor at the University of Massachusetts-Dartmouth. Mark is an expert on Nitrogen Isotope Biogeochemistry and especially its use to understand environmental responses to climate change. His work ranges from the global ocean to Long Island Sound and uses both water column and sediment samples.
