Abstract: From measurements of the flux of 8B solar neutrinos, the Sudbury Neutrino Observatory has now made significant contributions to solar and neutrino physics from both the initial 'pure D2O' and second 'salt' phases. A summary of results to date will be provided along with some details of the experimental procedures utilized. A description of detector calibration and systematic uncertainty evaluations for the salt phase will be given including energy, reconstruction, and background evaluations and with some emphasis placed on the differences between neutron response in the first and second phases of data taking. The impact of SNO results will be discussed with particular focus placed on the impact of the flux results on neutrino parameters. A brief account of the current phase of operation and future expectations will conclude the session.
