Talk Title:  From Microbial to Global: What Mercury Stable Isotopes Can Tell us about Mercury Bioaccumulation

Abstract:  Mercury (Hg) stable isotopes have become a standard approach to study Hg sources and processes in the environment. Despite the power of these tools, applying Hg isotopes to understand source to receptor relationships can be difficult due to the myriad of...

Title: Influence of fluid-assisted healing on fault permeability structure

Abstract:
Micro-cracks in fault damage zones can heal through diffusive mass transfer controlled by temperature and pressure. The diffusion of pore fluid pressure in fault damage zones...

Dr. Anna M. Michalak is a faculty member in the Department of Global Ecology of the Carnegie Institution for Science and a professor in the Department of Earth System Science at Stanford University. She studies the cycling and emissions of greenhouse gases at urban to global scales – scales directly relevant to informing climate and policy – primarily through the use of atmospheric observations. She also explores climate change impacts on freshwater and coastal water quality via influences on nutrient delivery to, and on conditions within, water bodies. Her approach is focused on the...
