Widespread deployment of sensors that measure river nitrate (NO3−) concentrations has led
to many recent publications in water resources journals including review papers focused on …

New scientific understanding is catalyzed by novel technologies that enhance measurement
precision, resolution or type, and that provide new tools to test and develop theory. Over the …

Sensors and enabling technologies are becoming increasingly important tools for water
quality monitoring and associated water resource management decisions. In particular …

Microfluidic-based chemical sensors take laboratory analytical protocols and miniaturize
them into field-deployable systems for in situ monitoring of water chemistry. Here, we …

Most freshwater aquatic studies rely on Eulerian monitoring, ie, water quality and quantity
are monitored using grab samples or semi-continuous sensors deployed at fixed cross …

We describe a new approach that couples hydrograph separation with high‐frequency
nitrate data to quantify time‐variable groundwater and runoff loading of nitrate to streams …

Instream biogeochemical process measurements are often short-term and localized. Here
we use in situ sensors to quantify the net effects of biogeochemical processes on seasonal …

Biota imprint their stoichiometry on relative rates of elemental cycling in the environment.
Despite this coupling, producer‐driven diel solute variation in rivers and streams is more …

Abstract The Mississippi River and other large rivers have the potential to regulate nitrogen
export from terrestrial landscapes, and thus mitigate eutrophication in downstream aquatic …

River networks exhibit a globally important capacity to retain and process nitrogen. However
direct measurement of in‐stream removal in higher order streams and rivers has been …
