Noise is the New Signal: Moving Beyond Zeroth-Order Geomorphology - 2010 Sharp Lecture

Explore the cutting-edge concepts in geomorphology presented in this AGU Fall Meeting Sharp Lecture. Delve into the idea that "Noise is the New Signal" as Douglas Jerolmack challenges traditional approaches to Earth surface processes. Examine geomorphic transport laws, scale dependence, and the importance of defining length scales and coefficients. Investigate key questions surrounding geomorphic transport walls, diffusion equations, avulsion, and random cluster growth. Discover how percolation theory applies to robust geomorphic patterns and sediment transport systems. Gain insights into current research directions and future prospects in the field of geomorphology, moving beyond zeroth-order understanding to embrace the complexity and variability inherent in Earth's surface processes.
