Methane hydrates.
The interest in methane hydrates is worldwide.
Methane hydrates tend to underlie permafrost or continental margin sediments.
The workshop also had the benefit of presentations on other potential resources,such as methane hydrates.
Lastly, methane hydrates are being studied for future possibilities of exploitation.
It is estimated that the volume of energy trapped in methane hydrates exceeds the volume of all known conventional gas resources.
Methane hydrates are also receiving more attention among the climate research community.
Solid compounds of methane with water- methane hydrates- are found in significant amounts on the vast areas of the bottom.
Methane hydrates are estimated to contain nearly 30 times the amount of carbon dioxide in the atmosphere.
Bearing in mind the limitations of data and the problems associated with recoverability,the estimates of resources contained in methane hydrates are enormous.
With time, as conventional oil and gas reserves decline, methane hydrates are expected to become an economically important source of hydrocarbons.
As methane hydrates were sometimes found as deposits within sediments, as opposed to the rock strata of oil and gas wells, extraction could be a problem.
There does not yet exist a deeper-water marine mining industry involving polymetallic nodules, polymetallic sulphides,cobalt-rich crusts or methane hydrates.
Methane hydrates were formed in cold temperatures(4° C) and moderately high pressure zones 200 to 300 metres below land surface or at 400 metres of water depth.
We call on the Authority to consider placing other newly discovered resources-- such as sulphides,genetic resources and methane hydrates-- under the scope of its activities.
Extraction could present a problem, insofar as methane hydrates are sometimes found as deposits within sediments, as opposed to the rock strata of oil and gas wells.
At the same time, several delegations welcomed the Secretary-General's proposal to convene a workshop during 2000 on resources other than hydrothermal polymetallic nodules,including polymetallic sulphides, methane hydrates and cobalt-bearing crusts.
Scientists have estimated that the amount of organic carbon bound up in ocean-floor methane hydrates is twice that found in all recoverable and non-recoverable oil, gas and coal deposits on earth.
Methane hydrates, solid ice-like substances composed of water and natural gas(methane), occur in areas of the world's oceans where appropriate conditions of temperature and pressure cause water and methane to combine to form a solid.
According to some estimates the global amount of carbon stored in methane hydrates is estimated at 10,000 gigatonnes, which is nearly double the amount of carbon stored in all known fossil fuel deposits.
Current international concerns which have implications for the regime established in the Convention and the Agreement include the conservation and management of genetic resources in the international seabed area,the development of resources such as methane hydrates and the establishment of protected areas on the high seas.
Scientists have estimated that the amount of organic carbon bound up in ocean-floor methane hydrates is twice that found in all recoverable and non-recoverable oil, gas and coal deposits on earth.
Scientific studies of the economic geology of methane hydrates andpreliminary studies on the economic feasibility of methane hydrate production indicate that deposits spread in a thin layer across large areas may be less economically productive than thick vertically stacked deposits limited to smaller areas.
(2008) estimate that not less than 1,400 gigatonnes of carbon is presently locked up as methane and methane hydrates under the Arctic submarine permafrost, and 5-10% of that area is subject to puncturing by open taliks.
At the national level,at the United States Congressional hearings in July 2001, the Methane Hydrates Research and Development Act of 2000(Public Law 106-193) was considered to be"a good first step that should prove very beneficial now and in the years to come for evaluating investments in the[United States] ocean and energy future".99.
Some of the areas for which requests were received included: general information on the current activities and the functions of the Authority; law of the sea conferences; rights to the Arctic; fishing and navigation in the north-west passage;sustainable mining of sea floor massive sulphide deposits; methane hydrates and the work of the Authority in this area; the establishment of the Enterprise; and general information on sea floor massive sulphide deposits.
Relevance of the work is the need for the establishment of technical systems for the development of deepwater hydrocarbon energy(gas hydrates, methane hydrates), huge amounts of which are open Ukrainian geologists in the deep regions of the Black Sea and the oceans.
It was estimated that the methane hydrate fields could contain up to twice the amount of energy of the world's known hydrocarbon deposits oil, natural gas and coal.
The locations of all known mineral resources of the Area phosphorite, seafloor massive sulphides, polymetallic nodules,hydrocarbons and methane hydrate deposits.
Location of all known mineral resources, including placers, phosphorites, evaporates, polymetallic sulphides, manganese nodules,hydrocarbons and methane hydrate deposits.
