摘要

This project was conceived in response to NASA's stated goals to expand it's studies to global scales, and to focus on problems relevant to climate or other global change. As proposed, our research was for three years, for a geologic and remote-sensing study of the onset of glacial conditions between approximately 115 and 50 ka. We proposed to study the regionally extensive land surface record, rather than the temporally detailed record provided by stratigraphic cores. This approach is useful because it enables the depiction of fossil weather patterns, but it lacks the resolution and detail of the point studies. We intended to study transitions in desert soil types, rock coatings, and paleo ELA (equilibrium-line altitude) trend surfaces in Asia, western North America, and Australia. However, because of budgetary constraints, only 15 percent of the funding request was authorized, entailing a drastic downscape of the project. On the other hand, the project was augmented specifically to add a radar study of soil roughness and moisture in Queensland, Australia.
