High-frequency water quality measurements in streams and rivers have expanded in scope
and sophistication during the last two decades. Existing technology allows in situ automated …

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 …

Science is often driven forward by the emergence of new measurements. Whenever one
makes observations at a scale, precision, or frequency that was previously unattainable, one …

High-frequency water quality sampling is all the rage, and rightly so. Kirchner et al.(2004)
show how fine-scale data open up new insights into data structures. They note that new …

Eighteen months of 7-hourly analyses of rainfall and stream water chemistry are presented,
spanning a wide range of chemical determinands and building on over 20years of weekly …

In agricultural catchments, diffuse nutrient fluxes (mainly nitrogen N and phosphorus P), are
observed to pollute receiving waters and cause eutrophication. Organic matter (OM) is …

Excessive riverine nutrient concentrations threaten aquatic ecosystem structure and
functioning and can pose substantial risks to human health. Robust monitoring strategies …

Effective nutrient pollution mitigation measures require in‐depth understanding of spatio‐
temporal controls on water quality which can be obtained by analyzing export regime and …

Characterizing spatial and temporal variability in the fluxes and stores of water and water
borne constituents is important in understanding the mechanisms and flow paths that carry …

Advanced sensor technology is widely used in aquatic monitoring and research. Most
applications focus on temporal variability, whereas spatial variability has been challenging …
