This thanks to Joe Decker @ FB and his link to a blog post about Blood Falls, location of sulfur lifecycle critters.


* January 14, 2002 http://uanews.org/node/5745 About similar research in the Dry Valley area of Antartica. Note Taylor glacier flows off the plateau into Taylor valley (dry). http://en.wikipedia.org/wiki/File:Mcmurdo_sound_USGS_map.jpg

* Received 16 June 2006/ Accepted 13 April 2007 http://aem.asm.org/cgi/content/abstract/73/12/4029 DNA sequencing results "The bacterial 16S rRNA gene clone library was dominated by a phylotype that had 99% sequence identity with Thiomicrospira arctica (46% of the library), a psychrophilic marine autotrophic sulfur oxidizer. The remainder of the library contained phylotypes related to the classes Betaproteobacteria, Deltaproteobacteria, and Gammaproteobacteria and the division Bacteroidetes and included clones whose closest cultured relatives metabolize iron and sulfur compounds.

* 17 April 2009 http://astrobiology.nasa.gov/articles/life-at-blood-falls/ points to http://www.sciencemag.org/cgi/content/abstract/324/5925/397 Mikucki, J. A., Pearson, A., Johnston, D. T., Turchyn, A. V., Farquhar, J., Schrag, D. P., Anbar, A. D., Priscu, J. C., Lee, P. A. (2009). A Contemporary Microbially Maintained Subglacial Ferrous "Ocean". Science 324: 397-400 -- "These metabolic pathways result from a limited organic carbon supply because of the absence of contemporary photosynthesis, yielding a subglacial ferrous brine that is anoxic but not sulfidic.
