What are economic resources which can be extracted from the oceans ?
MINERAL RESOURCES OCEAN RESOURCES Marine resources include biotic, mineral and energy resources. The fertility of the sea is determined by oceanic circulation, biological processes of uptake and mineralization, settling of organic debris and regeneration of nutrients, migration of animals and the nutrient supply from land. The deep water of the Pacific and Indian Ocean is three times higher in nutrients than the Atlantic. The circulation of the north Pacific forms a trap for nutrients. The flora and fauna of the sea are immensely varied although they represent 16% of all species in the world. ” The phytoplankton are the minute plants on which all the other marine creatures depend for their living. Many of them are diatoms. Fertility based only on nutrient supply would be expected to be low and constant in the Tropics, low in summer but high in winter at 40 degrees and considerably higher all through the year at 60 degrees. Zoo plankton depends for its food on the phytoplankton. Two br
