Why is there Heavy Metal in Our Oceans? Envirotech Online

The water contained mercury, which found its way into the food chain of the local fish, and by a process of bioaccumulation, the concentration of mercury in the fish increased to toxic levels — the fish were subsequently eaten by the residents of Minimata. Over 1700 people died of mercury poisoning and the effects are still being felt today.

Seafloor Minerals - USGS

The seafloor contains deposits of minerals that we we use in everyday life such as copper, zinc, nickel, gold, silver, and phosphorus. These deposits occur as crusts on volcanic and other rocks and as nodules on abyssal plain sediment that are typically about 3 to 10 centimeters (1 to 4 inches) in diameter.

Deep sea mining - Wikipedia

Deep sea mining is a growing subfield of experimental seabed mining that involves the retrieval of minerals and deposits from the ocean floor found at depths of 200 meters or greater. As of 2021, the majority of marine mining efforts are limited to shallow coastal waters only, where sand, tin and diamonds are more readily accessible. There are three types of deep sea mining that have generated ...
