Marine resources encompass minerals and other materials of economic or intrinsic value found in oceans and on the seafloor, including dissolved salts and minerals in seawater, placer deposits like sand, gravel, gold, and diamonds on the seabed, manganese nodules, and hydrothermal deposits such as ferromanganese and massive sulfides containing valuable metals.
The mineral resources of the sea are important but at the same time they represent a risk to the environment due to their growing demand.
