Air clear spring water takes on an orange hue as a fluorescent water tracing dye (“Rhodamine WT”) swirls throughout Silver Spring in Florida. Dr. Erin White, a hydrogeologist, snorkels in the center of the swirl of Rhodamine WT. She and about a half dozen other graduate students, scientific divers, volunteers, and fellow lab-mates in Dr. David Kaplan’s Watershed Ecology Lab at the University of Florida joined forces to perform a series of these studies at freshwater springs throughout Florida. After the dye is released, they measure its concentration downstream with devices called fluorometers. This work helps them understand how the water moves and mixes and calculate the amount of time it spends in the river channel as it flows downstream from the headspring.
