<span style="color:black">Many processes in our environment are governed by physics: the seasonal overturning of a lake, the breaking of waves over coral reefs, and even the waving of wheat in a farmer’s field. In this presentation I will focus on two problems
in environmental fluid mechanics, and how we study them in an idealized laboratory environment. First, I will discuss remote characterization of seagrass beds by studying the overlying water surface; and second, I will address the role of stratification and
interfacial surface tension in subsurface trapping of oil spills. I will demonstrate the laboratory tools we use, and how results obtained in a tank in the lab can be applied to their associated real-world setting. Through these two case studies, I hope the
audience will gain an appreciation of the utility of idealized fluid mechanics experiments in isolating, studying, and furthering our understanding of the physics of our environment.</span></p>

<b><span style="color:black">Bio: </span></b><span style="color:black">Tracy Mandel received her B.S. in Environmental Engineering from Cornell University in 2012, and an M.S. and Ph.D. in Environmental Fluid Mechanics and Hydrology from Stanford University
in 2013 and 2018. She is currently a postdoctoral scholar at UC Merced in Physics and Applied Math, where her research focuses on the dynamics of oil plumes rising in stratified fluids. Her broader research interests include coastal hydrodynamics, experimental
methods in fluid dynamics, ecological fluid-structure interactions, and terrestrial canopy flows. She is also an enthusiast of puns involving fluid mechanics and vegetables.</span></p>
