Thus, accumulating accurate data prior to the advent of satellite imagery might be difficult to achieve. This would negate our ability to properly assess the unforseen consequences of decades of soil conservation efforts and how it has deprived the oceans of critical nutrients. I would think there should be some detectable signal in ocean floor samples, like diatom rain, i.e. something like the icecore data. It's something I would like to look into when I get a little more time. I agree that there certainly is not much in the general media about it, other than the few attempts at iron seeding. The comments you posted about China and soil conservation were very interesting, as the is the sort of gotcha that can creep up without people thinking about it. The Sahara has some very significant wind storms which oddly enough blow westerly, and must put a lot of dust in the N.Atlantic (IIRC, the dust can reach the eastern USA at times) It would be interesting to compare plankton there vs areas which have seen a decrease due to land practice changes. I don't think the Sahara has had significant land use changes which would affect dust storms off of it.
