HAPPY EARTH SCIENCE WEEK
Every year, AGI (American Geosciences Institute) organizes Earth Science Week "help the public gain a better understanding and appreciation for the Earth sciences and to encourage stewardship of the Earth." (AGI Earth Science Week). This year Earth Science Week is Oct. 14th-Oct. 20th and holds the theme of "Earth as an Inspiration". It is a celebration of the different areas of Earth science and how the Earth inspires us everyday.
Check out the newest audioEARTH podcast where hosts Joe and Railey speak with Sally Jewell about how geoscience impacts our daily lives, how young people can get involved with geoscience, and how the Earth inspires us each and every day.

The Influence of Multiple Scales in Fractured Media on Flow and Transport Properties
Dr. Jeffrey Hyman is a research scientist in the Computational Earth Science group at Los Alamos National Laboratory. His research combines applied mathematics, high performance computing, and subsurface hydrology to advance our understanding of complex subsurface hydrological systems. He received his PhD in Applied Mathematics with a PhD Minor in Hydrology and Water Resources from the University of Arizona in 2014. His current research focuses on discrete fracture networks modelling and what insights they can bring to a better understanding of flow and transport in fractured media.
Abstract: In low-permeability fractured media, such as granites and shales, flow and the associated transport of dissolved solutes is controlled primarily by fractures embedded within the rock matrix. The geometry of individual fractures, size and aperture, as well as the network structure determine the structure of the fluid flow field. However, the relevant lengths scales within a fracture network range several orders of magnitude and it is unclear which features of the network influence which flow and transport properties. One tool to investigate the interplay and influence of these multiple scales are discrete fracture network (DFN) models. In this talk, I’ll discuss recent studies that use high-fidelity DFN models that attempt to link flow and transport attributes to physical structures of a fracture network ranging in-fracture aperture variability to network-scale connectivity.
