From an ecological perspective, seal dust plays a crucial role in nutrient cycling within marine environments. The organic matter released into the ecosystem can serve as a food source for various microorganisms, subsequently supporting the entire food web. Phytoplankton, the primary producers of marine environments, benefit from the nutrients in seal dust, which can enhance their growth and, in turn, bolster the populations of herbivorous marine organisms.
