This core question is addressed by elucidating the interplay between physical, chemical and biological processes near the Earth’s surface, with a focus on the flows of energy (e.g., radiation), mass (e.g., sediments) and information (e.g., genes) across various spatiotemporal scales. The state, dynamics, and development of the Earth Surface System are controlled not only by gradual geologic, biologic and climatic processes, but also by sudden transitions that force cascading effects and feedbacks. NEXUS’s goal is to decipher, resolve, and constrain the mechanisms and effects of such transitions and their complex interplay within Earth Surface System and the human habitat it provides.
NEXUS: Earth Surface Dynamics seeks to:
