The first results! I received carbon isotope data of dissolved organic carbon (DOC) from Susan Lang (ETH Zurich) and sulfur isotope data of sulfate from Tim Heaton (British Geological Survey). There are definitely clear differences in the stream water chemistry of the two streams. Although a full interpretation will have to await the results of the rest of the chemical analysis, an initial overview is presented in a report submitted in conjunction with receiving the Arctic Field Grant which can be found below.
