AB A 200,000-yr interval of extreme global warming marked the start of the Eocene epoch about 55 million years ago. Neg. carbon- and oxygen-isotope excursions in marine and terrestrial sediments show that this event was linked to a massive and rapid (.apprx.10,000 yr) input of isotopically depleted carbon. It has been suggested previously that extensive melting of gas hydrates buried in marine sediments may represent the carbon source and has caused the global climate change.
Large-scale hydrate melting, however, requires a hitherto unknown triggering mechanism. The authors present evidence for the presence of thousands of hydrothermal vent complexes identified on seismic reflection profiles from the Voring and More basins in the Norwegian Sea. The intrusion of voluminous mantle-derived melts into carbon-rich sedimentary strata in the northeast Atlantic may have caused an explosive release of methane - transported to the ocean or atm. through the vent complexes - close to the Paleocene/Eocene boundary.
Similar volcanic and metamorphic processes may explain climate events assocd. with other large igneous provinces such as the Siberian Traps (.apprx.250 million years ago) and the Karoo Igneous Province (.apprx.183 million years ago).

TITLE: Enrichment in volatiles in the giant planets of the Solar System

AB We propose an interpretation for the enrichments in volatiles obsd. in the four giant planets with respect to the solar abundance. It is based on the assumption that volatiles were trapped in the form of solid clathrate hydrates and incorporated in planetesimals embedded in the feeding zones of each of the four giant planets. The mass of trapped volatiles is then held const. with time.
The mass of hydrogen and of not trapped gaseous species continuously decreased with time until the formation of the planet was completed, resulting in an increase in the ratio of the mass of trapped volatiles to the mass of hydrogen. The efficiency of the clathration depends upon the amt. of ice available in the early feeding zone.
The quasi-uniform enrichment in Ar, Kr, Xe, C, N, and S obsd. in Jupiter is reproduced because all volatiles were trapped. The non-uniform enrichment obsd. in C, N and S in Saturn is due to the fact that CH4, NH3, and H2S were trapped but not CO and N2. The non-uniform enrichment in C, N and S in Uranus and Neptune results from the trapping of CH4, CO, NH3 and H2S, while N2 was not trapped.
Our scenario permits us to interpret the strongly over solar sulfur abundance inferred by various modelers to be present in Saturn, Uranus and Neptune for reproducing the microwave spectra of the three planets. Abundances of Ar, Kr and Xe in these three are also predicted. Only Xe is expected to be substantially oversolar. The large enrichment in oxygen in Neptune with respect to the solar abundance, calcd. by Lodders and Fegley (Icarus 112 (1994) 368) from the detection of CO in the upper troposphere of the planet, is consistent with the trapping of volatiles by clathration. The upper limit of CO in Uranus does not exclude that this process also occurred in Uranus.
Yup, that's him, playing the "thoughtful" Klingon, Maltz... the only one to survive Star Trek III.
And yes, that's Reverend Jim...
John Larroquette as the Klingon crewman Maltz on Star Trek III: the Search for Spock.
Thanks. I just lost $1. Funny watching him freak when I said "No he did'nt". Like it mattered or something.
See #23
It would be funny if the ST3 DVD had Chris Lloyd outtakes of him doing the Klingon as Rev. Jim.

From Uranus?
I saw "Blacksheep" on the History Channel. "Oh s***, that's DAN FIELDING!"
If you want to win your buck back (and provided he's not reading over your shoulder)
Ask him if he knows-
What was Spock's mothers name (Amanda)
or
How many bathrooms does the NCC-1701D have?(answer 1)
LOL Touched a nerve I see! I meant in the greater scheme of things "matter", not "your're a dork even though I'm a sci-fi junkie and total frickin hypocrite" matter. I'm a total 'Dune' freak. Star Wars is pretty cool too. I'm in a major Alternate History phase right now.
That brings to mind the old joke:
What does the star ship Enterprise have in common with a roll of toilet paper?
They both circle Uranus looking for Klingons.
They both circle Uranus looking for wiping out Klingons.
Soooo....... you're the one! ;9) LOL!
