INTEGRATING CONTINUOUS SENSOR DATA WITH OBSERVATIONAL SAMPLING AT A CONTINENTAL SCALE TO ENABLE ESTIMATES OF CARBON FLUX, REAERATION AND METABOLISM IN STREAMS
The National Ecological Observatory Network (NEON) deploys instrumentation and collects samples on a continental scale in atmospheric, terrestrial, and aquatic systems. Measurement collocation across these components allows for linking and comparing data related to ecological parameters across air, land, and freshwaters. The NEON aquatic program will enable quantifying the impacts of climate change, land use, and biological invasions on freshwater populations and processes. Data processing of NEON measurements is standardized, quality-controlled, and freely available through a publicly accessible online data portal (data.neonscience.org). Samples are collected bi-weekly from 24 streams and 3 rivers and monthly from 7 lakes for dissolved greenhouse gas concentrations (CO2, N2O, and CH4) and water chemistry, including dissolved organic carbon concentrations and alkalinity. At the same time, sensors collect data at aleast every 5 minutes for dissolved oxygen, pressure (water level), temperature, PAR, and fDOM, a DOC proxy. At stream sites, reaeration tracer experiments (simultaneous conservative and gas tracer injection) are performed 6 times per year. Dissolved gas concentrations, physical parameters, continuous discharge, and inorganic and organic carbon concentrations derived from the NEON dataset enable estimates of metabolism and carbon fluxes in streams.
