Great looking results. But, I'm wondering how they relate to the original hypothesis: How does natural gas fracking contribute to air pollution? Also, the link under the "An Experiment project you backed has posted a new lab note!" is identical to the link with "How does natural gas fracking contribute to air pollution?" that is identical to the link "Maria's poster for upcoming workshop". My expectation was that these three links would lead to three different sets of data/perspective.

I need a little more information to make sense of this: 1) Why are nitrate isotopes processed differently by the sun?, 2) How do you calibrate this difference?, 3) What exactly is the point for measuring the difference between "normal" nitrates and "nitrate isotopes" in this process? That is: Why do you expect this to have a substantial impact on the outcome?, 4)How many different nitrate isotopes are you tracking?, 5) The dusty cap curve vs. the old curve makes total sense from an exposure point of view. Is there something really interesting about this?, 6) How different would the dusty cap curve be from the old curve if the only isotope of nitrate you looked at was the most common?, 7) If there is no difference, why are we even talking about isotopes - something that normally has no bearing in common chemistry? Thanks, and sorry for being a pain in the ass. -Ron

Make sure you obtain a comprehensive record of winds over the geographic location you are collecting snow so that you can rule out contaminants from areas far outside of your study area.
