Formation of Marine Biological Thin Layers: Recruitment of Zooplankton
Abstract
Localized accumulations of planktonic organisms are well known as a result of physical and chemical oceanographic conditions. Since zooplankton are commonly endowed with effective sensory and locomotor apparatus, they also may aggregate or disperse on the basis of biological drives of many types. For example, mating aggregations or swarms may be guided by pheromones or bioluminescent signaling. Grazing and predation are also major influences on local distribution of organisms. It is likely that accumulations of organisms induced by physical or chemical states, for example, phytoplankton thin layers, might serve to influence accumulation or dispersal of zooplankton equipped to sense and orient to them. Our goal in this work is to train an ASSERT Fellow in the techniques of our several research units and apply them to this question of higher order orientation of zooplankton. The ASSERT Fellow is Ms. Christy Herren. She is scheduled to complete her PhD dissertation during this academic year.
