Manganese nodules. Photograph of the floor of the North-East Atlantic Ocean,showing a large field of manganese nodules. Manganese nodules form when manganese and iron minerals are deposited on the surface of an object such as a tiny piece of bone. The minerals in the sea water deposit over a long time; a nodule grows by 1 centimetre in diameter in about 1 million years. Some fields of nodules,particularly in the Eastern Pacific,may one day be 'harvested' (mined) commercially. This photo was taken at a depth of 5350 metres using a purpose-built camera | |
