TURBULENT MASS TRANSFER: AN INTRODUCTION TO SCALING, MEASUREMENT, AND IMPACTS

Interest in the physical processes that shape (literally and figuratively) the biology, geomorphology, and geochemistry of aquatic habitats has grown dramatically within the past two decades. Because turbulent water flow is the primary mechanism for the transport of biological and geochemical material over scales of mm to km, empirical and modeling studies of turbulent mass transport have been especially incisive in advancing our understanding of critical ecological (e.g. larval settlement), physiological (e.g. photosynthesis), and geochemical (e.g. mineralization) processes. Using examples from my own research in odor dispersal, suspension feeding, and nutrient transport I will introduce the topic of turbulent mass transfer, the scales over which turbulence is important, some methods for measuring water flow and material flux, and the impacts on biological and geochemical processes. The goal of this presentation is to highlight the varied research fields involved in studying turbulent transport processes and set the stage for the remainder of this session.
