The first year of the project "Ecolological aspects of deepsea mining" was dedicated to field sampling campaigns in the polymetallic nodule areas of the Eastern Equatorial research expeditions focused on investigating different types of seafloor disturbances in the deep sea that were created from a few days and months up to almost 40 years ago.
Dec 17, 2016· Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend.
As terrestrial mineral deposits are either depleting or of low grade, minerals from the deepsea like the polymetallic nodules, cobalt rich crusts and polymetallicsulfides are considered as alternative sources for metals such as Cu, Ni, Co, Mn, Fe, that could be exploited in future by developing suitable technologies for mining as well as extracting metals from them.

Apr 25, 2017· What Is The Environmental Impact Of The Mining Industry? Water pollution, loss of biodiversity, soil erosion and pollution, and formation of sink holes are among the worst effects of the mining industry on the environment.
• Deepsea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.
Deep sea mining is a mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean''s surface.

The beginning : Oceanography was still an amateur science when the HMS Challenger (left) set sail in December 1872. She returned in May 1876 with vast information that laid the solid foundation of oceanography. The first discovery of Polymetallic nodules also begins with this historic voyage of Challenger; on the 7th March 1873 the dredge hauled up on its deck ''several peculiar black oval ...
Mining on the ocean floor could do irreversible damage to deep sea ecosystems, says a new study of seabed mining proposals around the world. The deep sea (depths below 200m) covers about half of the Earth''s surface and is home to a vast range of species.
