Abstract : During the austral summer, the snowmelt runoff at McMurdo Station is quite unique and variable. As the temperature gradually warms up, McMurdo staff clears winter snow and ice accumulation in the drainage channels to accommodate the incoming snowmelt runoff. This ephemeral flow is observed as diurnal daily fluctuation throughout the austral season and varies depending on the air temperature and many other factors. In addition, the runoff mobilizes sediment that is washed into these channels and transports contaminants into to Winter Quarters Bay and McMurdo Sound. The overall goal of this document is to provide guidance for operation and maintenance of in-town roads and the drainage system. The processes and steps referred to in this document require further verification to incorporate lessons learned and to promote appropriate best practices.
