      Deep-ocean polymetallic nodules (also known as manganese nodules) are composed of iron and manganese oxides that accrete around a nucleus on the vast abyssal plains of the global ocean .   Deep-sea mining has the potential to supply cobalt and other metals free from association with such social strife, and can reduce the raw material cost and carbon footprint of much-needed green technologies. On the other hand, concerned scientists have highlighted our limited knowledge of the deep-sea and its ecosystems.

    The industrialization of the deep sea is expanding worldwide. Increasing oil and gas exploration activities in the absence of sufficient baseline data in deep-sea ecosystems has made environmental management challenging. Here, we review the types of activities that are associated with global offshore oil and gas development in water depths over m, the typical impacts of these activities.   The deep sea, the largest ecosystem on Earth and one of the least studied, harbours high biodiversity and provides a wealth of resources. Although humans have used the oceans for millennia, technological developments now allow exploitation of fisheries resources, hydrocarbons and minerals below m depth.

    Made up of Member States, and the European Union, the International Seabed Authority is mandated under the UN Convention on the Law of the Sea to organize, regulate and control all mineral-related activities in the international seabed area for the benefit of mankind as a whole. Antarctica - Antarctica - Economic resources: The search for economic resources led to the first sustained human interaction in Antarctica. Most early Antarctic expeditions through the 19th century had either direct or indirect economic incentives. For some expeditions, the search for new trading routes was the objective; for others, the objective was the opening of new fur-sealing grounds or.

Exploration and exploitation of the deep-seas in search of marine minerals and genetic resources have over the past fifteen years received increased attention.

The articles in this issue explore the formation of deep-ocean mineral deposits; their inherent scientific value; and the geological, technical, environmental and economic challenges, as well as regulatory and philosophical questions, of extracting such mineral resources.

Deep-Ocean Mineral Deposits: Metal Resources and Windows into Earth Processes. Ferromanganese crusts, manganese nodules, phosphorites, and hydrothermal vent deposits, which occur in many deep ocean settings from the Arctic to the Antarctic, could be important sources of these metals and minerals.

Yet many economic, technological, and environmental challenges to deep ocean. The extraction of deep-sea mineral resources will have a significant impact on the marine environment, particularly its ecosystems. The scale and nature of these impacts remains uncertain and depends on the target resource and its associated ecosystems, and the technology used to extract the ore.

The Sustainable Exploitation of the Ocean’s Minerals and Resources. and the adverse effects of ocean acidification caused by increased absorption of carbon dioxide by the oceans, are among the biggest threats to the health of oceans and coastal areas.

Deep reductions in greenhouse gas emissions are. • Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 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. "The deep sea is the largest habitat on Earth, it is incredibly important to humans and it is facing a variety of stressors from increased human exploitation to impacts from climate change," said Andrew Thurber, an Oregon State University marine scientist and lead author on the study.

"As we embark upon greater exploitation of this vast. Ocean Economy. Inthe ocean-dependent economy generated $ billion or % of U.S. GDP; Coastal tourism & recreation dominated both employment and GDP in the ocean economy sectors with million jobs (75%) of employment and nearly $70 billion (51%) of GDP; Marine transportation had the second largest GDP, with $ billion, 20% of.

The world’s oceans are facing a “new industrial frontier” from a fledgling deep-sea mining industry as companies line up to extract metals and minerals from some of the most important.

A new report supports the creation of a compensation fund for nations that rely on. Framework for Deep Sea Minerals Exploration and Exploitation (‘the Framework’) presents key elements of the major topics discussed. 3 The Framework is designed to serve as a kind of “primer.

Unlocking the mysteries of deep-sea ecosystems can reveal new sources for medical drugs, food, energy resources, and other products.

Information from deep-ocean exploration can help predict earthquakes and tsunamis and help us understand how we are affecting and being affected by changes in Earth’s environment. Laws that protect exploitation and trade of deep sea minerals Due to geography and jurisdictional location of deep sea mining, the framework for financing and development of a deep sea mining project will include a complex set of agreements subject to various governing laws.

Deep sea mining is a mineral retrieval process that takes place on the ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1, to 3, metres (4, to 12, ft) below the ocean’s surface.

The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper. Rocks minerals and their exploitation (1) 1.
