Sentences with phrase «marine gas hydrate»

U.S. scientists working on a research vessel in the Gulf of Mexico have made the most promising discovery so far of marine gas hydrate, a possible new energy source.

Our results stress the importance of external climatic forcing of the dynamics of the seafloor, and the role of the rapid warming following the Younger Dryas in pacing the marine gas hydrate reservoir.

Knowledge of the timescales of gas hydrate dissociation and subsequent methane release are critical in understanding the impact of marine gas hydrates on the ocean — atmosphere system, says Shyam Chand, researcher at NGU / CAGE.

Not exact matches

«You build up too much free gas, and then you have an overpressured column,» says Gerald Dickens, a marine geochemist at Rice University who went to Hydrate Ridge on a drill ship in 2002.

Given the vastness of the world's marine methane hydrate deposits — more than twice the carbon reserves of all other fossil fuels combined — it's not surprising that government agencies and the petroleum and natural gas industries have long been interested in harvesting this new energy supply.

He is marine geologist at the Geological Survey of Norway (NGU) and Centre for Arctic Gas Hydrate, Climate and Environment, UiT The Arctic Univeristy of Norway.

In the greater NZ region, we have undersea hot springs (hydrothermal vents of the Kermadecs), marine hydrocarbon seeps and gas hydrates (offshore eastern North Island — possible analogues for oceans on Icy Worlds), and terrestrial (on land) hot springs in the Taupo Volcanic Zone and elsewhere around the country.

# 33 — Gavin, one of the papers cited by Shakhova is Gas and Possible Gas Hydrates in the Permafrost of Bovanenkovo Gas Field, Yamal Peninsula, West Siberia by Evgeny M.Chuvilin, Vladimir S.Yakushev and Elena V.Perlova, Polarforschung 68: 215 — 219, 1998 (erschienen 2000) shows marine hydrates at depths of 60m Hydrates in the Permafrost of Bovanenkovo Gas Field, Yamal Peninsula, West Siberia by Evgeny M.Chuvilin, Vladimir S.Yakushev and Elena V.Perlova, Polarforschung 68: 215 — 219, 1998 (erschienen 2000) shows marine hydrates at depths of 60m hydrates at depths of 60m to 120m.

Warming destabilises permafrost and marine sediments of methane gas hydrates in some regions according to some model simulations (Denman et al., 2007 Section 7.4.1.2), as has been proposed as an explanation for the rapid warming that occurred during the Palaeocene / Eocene thermal maximum (Dickens, 2001; Archer and Buffett, 2005).

When hydrates are present below permafrost, on land and beneath shallow marine shelves, they are also thermally buffered by the latent heat energy needed to melt the permafrost and it could take thousands of years to destabilize the gas hydrates (Taylor et al 2005).

The project at the University of Texas at Austin will develop conceptual and numerical models to analyze conditions under which gas will be expelled from existing marine accumulations of gas hydrate into the ocean, which could potentially have a damaging effect to the ecosystem.
