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.

Anodizing
Anodizing cannot peel off. The coating is part of the metal. Anodizing gives aluminum a deeper, richer metallic appearance than is possible with organic coatings. This is because an anodized coating is translucent, and one can see the base metal underneath the coating. Anodizing provides a thin aluminum oxide layer, which will deteriorate over time. Depending on the thickness and quality of the anodization, the surface should last 10-20 years.
