Soilscapes of the Western US: Perspectives on Change
Driven by curiosity about the Critical Zone, especially with regard to its sensitivity and vulnerability to global change impacts, the soil-landscape paradigm (once almost solely the rational construct for pedology) has become a major focus of attention for Earth and biological scientists. This interest was largely developed through the needs and contributions of pedologists exploring and positing key hypotheses relating the flow of water, biological activity (including nutrient cycling), and landscape evolution. This symposium will provide an overview of current research efforts in this arena. The Oral Session, scheduled for Monday morning, will consist of talks organized to define and exemplify approaches as well as provide forum for discussions on near-future research needs and methods. The Poster Session, scheduled for Monday afternoon, will consist of volunteer poster presentations which will be organized to center on detailed examples of Western soilscape studies.
