Dear Colleagues,

Please consider submitting your AGU abstract to EP053 - Where things aren't: Understanding the role of porosity in the Critical Zone. Our goal is to being together researchers doing cross-disciplinary work to examine porosity structure and evolution in the critical zone. Description below.

Abstracts due tonight! We look forward to seeing you in New Orleans!

Best,

Nicole West, Jorden Hayes, Jay Austin

 

EP053 - Where things aren't: Understanding the role of porosity in the Critical Zone

Over a decade of Critical Zone research suggests that landscape evolution is controlled by processes ranging from tectonic forces to energy fluxes associated with solar radiation and precipitation. These processes drive the generation of porosity through fracturing, mineral dissolution, and bioturbation. Porosity is essential to many life sustaining features of the critical zone and functions to provide organisms access to key nutrients, pathways for throughflow of meteoric and subsurface water, exposes surface area for chemical dissolution and mineral weathering, and allows for the entrainment and transport of particulates. Variations in porosity dictate critical zone architecture both spatially (vertically and laterally) and temporally. Our session aims to bring together a cross section of scientists working to integrate measurements from geophysics, geochemistry, hydrology, and ecology to elucidate porosity structure in the critical zone, and its correlation with physical, chemical, and biological processes.
