The oil coats aquatic life, impairing the gills of fish and the feathers of birds, which destroys their insulation and buoyancy. The interaction between the dispersant, the oil, and the water is complex, and the stability of the resulting micelles is a key factor in determining the overall success of the cleanup effort.
Oil on Water Density and Spreading Dynamics
However, this process trades a visible surface slick for potentially more damaging subsurface contamination. Since most oils are less dense than water, they do not sink but instead spread out to minimize their potential energy.
When white light hits the thin film, some of it reflects off the top surface of the oil, while the rest penetrates and reflects off the water-oil interface below. What appears as a shimmering, iridescent slick is actually a delicate balance of physical forces, where density differences are overcome by surface tension.
Oil on Water Density and Spreading Dynamics
This process, known as thin-film interference, amplifies certain wavelengths (colors) while canceling others, creating the brilliant blues, reds, and greens that change as the film thins or thickens. These chemicals reduce the surface tension of the water, allowing the oil to disperse more readily.
