Kerri and Kyle (Purdue Univ.) claim that their life at the Cake Eater Lab isn't exciting, but they are being modest! While at C.A.R.L. (Cake Eater Atmospheric Research Laboratory), I watched Kerri change the glass wool in the instrument halogen scrubber, take vertical profiles into the snow with the mass spectrometer, and clean the instrument inlet. We used a SWE (snow water equivalent probe) to bore a two inch diameter hole into the snow pack and put the insulated inlet tube down into the hole! Kerri constructed the insulated tube by nesting the regular teflon tube inside a copper pipe, coating it with heat tape, and making an outer layer of foam. We then used a fancy rigging of string and zip-ties to suspend it at our desired height. :) Measurements were taken at several heights above the snow and into the hole in the snow to investigate halogen activation from the snowpack.
