Center for Isotope Geochemistry

Core Capabilities
People

MassSpec-Kennedy-CIG

The Center for Isotope Geochemistry (CIG) is a joint-institution research center, with labs both at LBNL and UC Berkeley. This state-of-the-art analytical facility was established in 1988 to measure the concentrations and isotopic compositions of elements in rocks, minerals, and fluids in the earth’s crust, atmosphere, and oceans. CIG has a community of roughly 25 people—scientists, research lab staff, postdoctoral researchers, graduate students, and administrative/computer support staff. It is directed by Donald J. DePaolo, (Associate Lab Director for Energy Sciences) at Lawrence Berkeley National Lab, and Class of 1951 Professor of Geochemistry, Department of Earth and Planetary Science, UC Berkeley.

New Report Explores Revolutionary Environmental Artificial Intelligence Infrastructure

January 10, 2023

In a collaborative effort between the U.S. Department of Energy’s (DOE) Office of Biological and Environmental Research (BER) and DOE’s Advanced Scientific Computing Research (ASCR) program, as well as with community experts, the Artificial Intelligence for Earth System Predictability (AI4ESP) workshop was held from October through December 2021. BER developed the process as the Model-Experiment paradigm, or ModEx, and a report released this fall outlines the key takeaways of last year’s event.
