Each night, animals (particularly crustaceans) swim out of the seabed into the water column, a phenomenon termed "emergence." The distribution of these optical and acoustic scatterers is not well known in time and space. The cues that trigger the behavior, the environmental factors that modulate it, and the underlying ecological mechanisms that drive it are just beginning to be elucidated. My long-term goal is to understand this phenomenon to the point that variation in space and time are predictable and mechanistically understood.
