The second grant, titled “Collaborative Research: Spatial variability in eroded sediment size and geomorphic processes inferred from detrital thermochronometry and cosmogenic nuclides”, will support groundbreaking work on combining cosmogenic nuclides and detrital thermochronometry and help fund PhD student Claire Lukens. The third grant, entitled “NSF Workshop: Drilling, Sampling and Imaging the Depths of the Critical Zone” will support an international workshop in Denver, Colorado, from October 24-26, 2013. Outcomes from two of the three grants will leverage contributions from the new Wyoming Center for Environmental Hydrology and Geophysics (WyCEHG).
