Sentences with phrase «how methane hydrates»

«How methane hydrates behave can have a big impact on safety, environmental issues and climate change.»

Over the years, as researchers have returned to the place they named Hydrate Ridge, they have learned a lot about how methane hydrate is created there.

The School of Mines will conduct a series of laboratory experiments to determine how methane hydrate can be detected using seismic methods with the goal of increasing the reliability and accuracy of seismic readings in methane hydrates.

In a paper published in the 2 November edition of Nature Communications, corresponding author Zhang and his colleagues describe how they used a computer simulation of two types of methane hydrates, monocrystalline hydrates and polycrystalline hydrates, to see what would happen if they were compressed or if pressures on the hydrates were suddenly released.

But that study said it is uncertain how much hydrates contribute to the methane emissions, as opposed to other sources such as the decomposition of organic matter in permafrost as it thaws.

I have posted on RealClimate about 4 times in the past 5 years regarding the potential thaw of the methal hydrate deposits at the bottom of the oceans.I stated in my posts on your website that I believe firmly that those deposits are in quite a good bit of danger of melting from climate change feedback mechanisms.On Nov 8th, ScienceDaily posted a huge new study on the PETM boundary 55 million years ago, and some key data on how the methane at that point may very well have melted and contributed to the massive climate shift.I am an amateur who reads in the new a lot about climate change.I'd now like to say «I told you so!!!»

SkS: In your JGR paper from 2010 you state that methane hydrate in Siberia can occur at depths as shallow as 20 m. Have any such remarkably shallow methane hydrate deposits on the ESAS been directly observed / sampled and if so, how could methane hydrate have formed at such depths?

How would the volume of methane from the amount of hydrates in a hole that size (taking hydrate density into account) compare with the volume of methane you calculated?

Consider just how much commercial cred fracked gas & oil had 10 yrs ago, and then look at the current worldwide research efforts both on methane hydrates» extraction and also on coal - seam gasification.

Elsewhere in the same paper, Archer describes how this could come from the methane trapped in the ice being smoothed through «diffusion within the fern or heterogeneous bubble closure depth,» or simply through the methane sampling not being dense enough, where the maxima of release could be overlooked [Archer, Methane hydrate stability and anthropogenic climate change, Biogeosciences,methane trapped in the ice being smoothed through «diffusion within the fern or heterogeneous bubble closure depth,» or simply through the methane sampling not being dense enough, where the maxima of release could be overlooked [Archer, Methane hydrate stability and anthropogenic climate change, Biogeosciences,methane sampling not being dense enough, where the maxima of release could be overlooked [Archer, Methane hydrate stability and anthropogenic climate change, Biogeosciences,Methane hydrate stability and anthropogenic climate change, Biogeosciences, 2007].

How long will soils remain hydrated enough to produce methane over CO2?

What is concerning is the possibility that rapid global warming could occur faster than many people believe is possible, if global warming due to atmospheric carbon dioxide causes the Earth's atmosphere to warm enough to release enormous deposits of frozen methane (CH4) that are stored in the permafrost above the Arctic Circle and in frozen methane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane (CH4) that are stored in the permafrost above the Arctic Circle and in frozen methane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane ice, known as methane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human Extinmethane hydrate, underneath the floors of the oceans throughout the world (see: How Methane Gas Releases Due To Global Warming Could Cause Human ExtinMethane Gas Releases Due To Global Warming Could Cause Human Extinction).

It is also worth noting that the use of both modes of Geo - E in a Troika strategy can not entirely guarantee a benign outcome, however long the R&D period, since we have no firm information on how large the response the Methane Hydrates Melt feedback will be to the sum of ocean warming that is already penetrating the seabed plus that from the several decades of further warming as the natural sea temperatures are slowly restored.

Experiments to assess how large a rise in deep sea temperature would be required to gasify solid methane hydrate suggested that a rise of 5 °C would be sufficient.

The average methane clathrate hydrate composition is 1 mole of methane for every 5.75 moles of water, though this is dependent on how many methane molecules «fit» into the various cage structures of the water lattice.

The nominal methane clathrate hydrate composition is (CH4) 4 (H2O) 23, or 1 mole of methane for every 5.75 moles of water, corresponding to 13.4 % methane by mass, although the actual composition is dependent on how many methane molecules fit into the various cage structures of the water lattice.

The 12/12/2005 RC article on methane hydrate (I'm sorry but I don't know how to provide the url) refers to large hydrate deposits along the Oregon and Gulf coasts.

Most methane hydrate is far enough below the sea floor that sediments serve as an insulating layer, limiting how fast heat can spread downward.

But having made my point, I probably shouldn't hijack this interesting post about methane hydrates any further — I guess we should try to work out how to extract and burn them to avert the peak oil crisis risk of release: --RRB-
