We present spectrally and specially resolved ALMA observations of 13CO and C18O 3-2 and 6-5 in the protoplanetary disk TW Hya. These observations provide a measurement of the surface CO snowline at ~30 AU and constrain the likely location of the midplane CO snowline to 17-23 AU. Additionally, the 3-2 maps show evidence for an outer ring of CO centered at 53 AU. Using these observations, combined with previous observations, we have estimated the azimuthally averaged gas temperature, CO, and H2 gas surface density profiles. These represent the first resolved estimates of the abundance of a major volatile in a young planet forming disk. We find that the abundance of CO is depleted in the gas by two orders of magnitude relative to the expected value, based on abundance in the interstellar medium. This depletion is observed from our resolution limit of 10 AU out to the edge of the detected emission at 60 AU. Furthermore, we will present additional lines of evidence which demonstrate the missing carbon is likely locked up in the midplane as ices coating pebbles and perhaps even cometesimals. This traces the beginnings of the implantation of key volatiles into the solids.
