SEABED MINING: WHAT YOU NEED TO KNOW
INTRODUCTION
Sea bed mining, also known as deep sea mining, is the process of obtaining precious minerals and commodities from the ocean floor. These resources include precious metals, minerals, and even rare earth elements. The objective of sea bed mining is to provide a new supply of valuable materials for human use, as traditional land-based mining activities grow increasingly difficult and expensive.
A brief history of sea bed mining may be traced back to the 1960s, when the United Nations Convention on the Law of the Sea was founded. This treaty allowed countries the right to explore and utilize the resources of the deep sea inside their Exclusive Economic Zones (EEZs) (EEZs). In recent years, breakthroughs in technology have made sea bed mining more economically possible, and the business is now starting to gain speed.
The current condition of the sea bed mining business is still in its early phases, with only a few experimental projects now active. However, it is likely to rise substantially in the next years, as demand for resources continues to climb and technology improves.
Forms of Sea Bed Mining:
There are various distinct types of sea bed mining, each with its own unique qualities.
Placer mining: This form of mining involves the extraction of minerals that have been deposited in riverbeds, beaches, or other coastal regions.
Polymetallic nodules mining: This form of mining involves the extraction of nodules, which are tiny, spherical balls of metal and minerals that may be discovered on the deep-sea floor.
Seafloor massive sulfides mining: This form of mining includes the extraction of massive sulfide deposits, which are rich in precious metals such as copper, zinc, and gold.
Cobalt-rich ferromanganese crusts mining: This form of mining involves the extraction of cobalt-rich ferromanganese crusts, which are located on the shallow sea floor and are rich in cobalt, nickel, and other precious metals.
Economic Potential:
Sea bed mining has great economic potential, since it provides a fresh supply of precious minerals and commodities that may be used in a wide range of sectors. The materials and resources that may be taken from the sea floor include precious metals, minerals, and rare earth elements. These materials have enormous economic value and may be employed in a wide range of sectors, including electronics, renewable energy, and transportation.
The present market value of these resources is considerable, and is likely to continue to climb as demand for them increases. For example, the price of cobalt, a major component in lithium-ion batteries used in electric vehicles, has more than quadrupled since 2016. Similarly, the price of rare earth elements, which are employed in a wide range of high-tech applications, has also been growing significantly in recent years.
Sea bed mining also has the potential to produce jobs in coastal towns, notably in the fields of mining, transportation, and processing. Additionally, sea bed mining has the potential to offer a considerable boost to the economy of nations where it takes place, particularly in underdeveloped countries that have significant quantities of deep-sea minerals.
However, it is crucial to emphasize that the sea bed mining sector is still in its early phases, and there are still many uncertainties and problems that need to be solved before it can fully fulfill its economic potential. The industry is capital-intensive and requires substantial investment. Additionally, the environmental and social implications of sea bed mining need to be thoroughly examined and mitigated to guarantee that it may be developed in a sustainable and responsible way.
Environmental Impact:
Sea bed mining has the potential to have negative effects on ecosystems and marine life, among other things.
The process of sea bed mining can physically harm the sea floor and the environment, which can harm or kill marine species that live in the region. This has an impact on marine life and ecosystems. Chemicals and heavy machinery use have the potential to be detrimental to marine life. For instance, the noise from mining operations can disturb marine mammals’ habits, including those of whales and dolphins, and the use of chemicals can harm or even cause the extinction of species that live on or close to the sea floor. Additionally, the removal of silt may cause changes in the ecosystems of the seafloor, which would reduce the biodiversity of the region.
Sea bed mining may release pollutants including silt, heavy metals, and other dangerous compounds into the ocean, which can have an impact on the quality of the water. This can harm or even kill local marine animals, as well as negatively affect the health of coastal communities that depend on fishing and other ocean-based industries for their survival. Dead zones in the ocean may also be created by the discharge of mining waste when the oxygen level is too low to support marine life.
Sea bed mining may also have a significant effect on coastal communities, especially those that depend on fishing and other ocean-based industries for their livelihoods. These individuals may find it difficult or impossible to fish or utilize other marine resources in the area due to the physical damage that mining operations have caused on the sea floor. The health of these communities and the marine organisms on which they depend can both be harmed by the release of toxins into the sea.
Oil leaks and other incidents are a possibility with sea bed mining, which might have serious negative effects on the ecosystem. For instance, an oil spill might harm or kill marine life and ruin the ecology of the ocean, and a chemical or mining disaster could cause a comparable amount of devastation. To reduce the likelihood of accidents and spills, it is essential to have a comprehensive accident management strategy in place and to ensure that safety procedures are followed.
In general, sea bed mining has the potential to have negative effects on the environment, particularly on marine life and ecosystems, water quality, coastal people, and the possibility of oil spills and other disasters. To ensure that sea bed mining is carried out in a sustainable and responsible manner, it is essential that these consequences be fully assessed and that standards and best practices are put into place.
The cumulative consequences of sea bed mining must also be taken into account since they might affect marine life and ecosystems broadly in addition to locally. For instance, the removal of silt and physical harm to the sea bottom can alter the ocean’s circulation and upset the food chain, which will result in a decrease in the region’s biodiversity. The effects of sea bed mining can go beyond the mining site and harm the ecology in ways that are yet not completely understood.
Furthermore, sea bed mining has the potential to harm the distinct, delicate, and little understood deep-sea ecosystems. The destruction of these habitats might result in the extinction of yet-to-be-discovered species since these ecosystems are home to a wide range of unusual creatures that have adapted to the harsh conditions of the deep sea.
A complete environmental impact assessment (EIA) must be carried out prior to the start of mining activities in order to reduce the environmental impact of sea bed mining. An evaluation of the possible effects on marine life and ecosystems, water quality, coastal communities, and the risk of oil spills and other incidents should be part of this. Mitigation strategies can be devised based on the EIA’s findings to lessen the environmental effect of mining.
The creation of laws and industry standards that guarantee sustainable and ethical sea bed mining is another crucial factor to take into account. In addition to developing standards for observing the environmental effect of mining activities, this also entails developing rules for the use of chemicals and large gear. In addition, it’s crucial to make sure that the sector develops transparently with the right level of stakeholder participation.
