trace metals in the ocean

Trace metals in the ocean are small amounts of metal elements, like iron, copper, and zinc, that are crucial for marine life. Despite their low concentrations, these metals play vital roles in processes such as photosynthesis and respiration in ocean organisms. They originate from various sources, including rivers, dust, and oceanic vents. While essential, excess levels of some trace metals can be harmful, impacting ecosystems and human health. Understanding their distribution and behavior in ocean water helps scientists monitor ocean health and manage resources effectively.
