The National Ecological Observatory Network (NEON) is a National Science Foundation funded project designed to collect long-term, open-access data to better understand ecological change at continental scales. NEON includes 34 freshwater aquatic field sites spread across 19 different ecoclimatic regions, from Puerto Rico to Alaska. These sites are instrumented with an array of automated sensors collecting meteorological, hydrological and biogeochemical data at high-frequencies. This data is made publicly available to prospective users through the NEON data portal. This workshop will teach participants how access, interpret, manipulate and visualize this data; a basic familiarity with R is required.
