Untitled
This article doesn't tell us anything about the hydrogen cycle (if it exists). The external link is a lecture on the carbon cycle.
 * I've never heard of it, wikified the article slightly--Alex 10:39, 28 September 2006 (UTC)

Article Makeover
Hi all, I've been doing research on the H2 cycle and microorganisms that utilize atmospheric H2 for the past 1.5 years. I really want to improve this article because it is not doing the H2 cycle justice--especially considering that H2 is a secondary GHG. I'd of course like help along the way, so let's keep this discussion alive as the page improves! Please message me via this page or my user page. Wikisyzygy (talk) 03:26, 14 December 2012 (UTC)
 * Hi Wikisyzygy, I like the changes you made except that for the first sentences of the lead section which is now missing. I believe the article would not be compatible without that according to WP:BOLDTITLE, since the lead section is now very confusing. Are you going to add a brand new lead section or revert the old one? The Ocean (talk) 21:24, 30 December 2012 (UTC)

External links modified
Hello fellow Wikipedians,

I have just modified one external link on Hydrogen cycle. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
 * Added archive https://web.archive.org/web/20060919111100/http://whitman.myweb.uga.edu/coursedocs/mibo8610/de%20bok%20et%20al%2004.pdf to http://whitman.myweb.uga.edu/coursedocs/mibo8610/de%20bok%20et%20al%2004.pdf

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

Proposed hydrogen cycle updates
I would like to increase this page's coverage to include additional aspects relevant to the hydrogen cycle. While the elemental hydrogen page is robust and describes many processes related to the natural and anthropogenic fluxes of hydrogen on Earth, it only includes limited discussion biogeochemical reactions. I think this cycling-specific article should describe these processes and their interdependencies in greater detail. Currently, this page really only includes interspecies hydrogen transfer (IHT) as an example of a biologically mediated process, and I would like to expand it along the following draft framework over the coming weeks:


 * Introduction
 * More general introduction to terrestrial hydrogen cycling prior to IHT discussion
 * Links to the general hydrogen page should be established
 * Sources & Sinks
 * Elaborate on the current list, tie to microbial metabolisms (expanded on below) along with abiotic and anthropogenic activities (without duplicating similar information on the Hydrogen page). Include geologic scale processes, e.g. serpentinization, atmospheric escape
 * Relevant Metabolisms
 * flux of water / light reactions of photosynthesis. relate to carbon/hydrocarbon cycle
 * influences of sulfate reduction, hydrogen oxidation, methanogenesis on hydrogen cycle
 * Global Climate Implications
 * expand upon current section describing hydrogen and methane interaction in the atmosphere
 * Broader context
 * Link to Hydrothermal vent, Abiogenesis, redox discussions
 * Astrobiology: implications of evidence for the operation of a hydrogen cycle on other bodies warrants mentioning
 * References
 * Add inline citations to current research
 * Merge the duplicative references and bibliography sections
 * General: Improve article organization and flow. Improve relevance of 'see also' section and 'external links' sections.
