Hi Folks, Bhaskar, this is what I was hoping to see. Your input is important. BTW, The diatom activity in the Gulf of Mexico (spill effected area) has just collapse by around 3,000 percent and I will forward a link as soon as I find it.
I am aware of the iron hypothosis and was hoping you would bring up that connection. I will be on Mt. Baker for the next week and will post more when I can. Thank you for your imput. PS. John, I have a few engineering ideas on how to farm these mats. Arctic conditions would not be included in the concepts. Also, I am trying to find any info on what troposperic sulfide injection would do to the AOM biota. I am suspectiong that any sulfide which precips out over a methane field will support the anaerobic food chain.
