Marine minerals are naturally occurring substances found in the ocean, including salts, metals, and other elements. These minerals are essential for various biological processes and play a crucial role in maintaining the health of marine ecosystems. Common marine minerals include sodium chloride (table salt), magnesium, and calcium, which are vital for both marine life and human use. In addition to their biological importance, marine minerals are also valuable resources for industries. For example, manganese nodules and polymetallic sulfides found on the ocean floor contain precious metals like gold and silver. The extraction and sustainable management of these resources are important for economic development and environmental conservation.
