Influence of transient storage on stream nutrient uptake based on substrata manipulation

Creator:: Argerich, Alba, Marti, Eugenia, Sabater, Francesc, Haggerty, Roy, and Ribot, Miquel
Abstract:: Quantification of the transient storage zone (A[subscript s]) has become critical in stream biogeochemical studies addressed to examine factors controlling nutrient uptake. It is expected that higher A[subscript s] may enhance the interaction between nutrients and biota and thus, increase nutrient uptake. However, results from the literature are controversial. We...

A field comparison of multiple techniques to quantify groundwater–surface-water interactions

Creator:: González-Pinzón, Ricardo, Ward, Adam S., Hatch, Christine E., Wlostowski, Adam N., Singha, Kamini, Gooseff, Michael N., Haggerty, Roy, Harvey, Judson W., Cirpka, Olaf A., and Brock, James T.
Abstract:: Groundwater–surface-water (GW-SW) interactions in streams are difficult to quantify because of heterogeneity in hydraulic and reactive processes across a range of spatial and temporal scales. The challenge of quantifying these interactions has led to the development of several techniques, from centimeter-scale probes to whole-system tracers, including chemical, thermal, and electrical...

Defining and measuring the mean residence time of lateral surface transient storage zones in small streams

Creator:: Jackson, Tracie R., Haggerty, Roy, Apte, Sourabh V., Coleman, Anthony, and Drost, Kevin J.
Abstract:: Surface transient storage (STS) has functional significance in stream ecosystems because it increases solute interaction with sediments. After volume, mean residence time is the most important metric of STS, but it is unclear how this can be measured accurately or related to other timescales and field-measureable parameters. We studied mean...

Quantification of metabolically active transient storage (MATS) in two reaches with contrasting transient storage and ecosystem respiration

Creator:: Argerich, Alba, Haggerty, Roy, Marti, Eugenia, Sabater, Francesc, and Zarnetske, Jay
Abstract:: Water transient storage zones are hotspots for metabolic activity in streams although the contribution of different types of transient storage zones to the whole-reach metabolic activity is difficult to quantify. In this study we present a method to measure the fraction of the transient storage that is metabolically active (MATS)...

Development of a “smart” tracer for the assessment of microbiological activity and sediment-water interaction in natural waters: The resazurin-resorufin system

Creator:: Haggerty, Roy, Argerich, Alba, and Marti, Eugenia
Abstract:: A “smart” tracer is a tracer that provides, directly or through measurement of its concentration or in combination with another compound, at least one “bit” more of information about the environment through which it travels than a conservative tracer. In this study we propose and present the chemical compound resazurin...

Quantifying spatial differences in metabolism in headwater streams

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, and Argerich, Alba
Abstract:: Stream functioning includes simultaneous interaction among solute transport, nutrient processing, and metabolism. Metabolism is measured with methods that have limited spatial representativeness and are highly uncertain. These problems restrict development of methods for up-scaling biological processes that mediate nutrient processing. We used the resazurin–resorufin (Raz-Rru) tracer system to estimate metabolism...

Dynamics of nitrate production and removal as a function of residence time in the hyporheic zone

Creator:: Zarnetske, Jay P., Haggerty, Roy, Wondzell, Steven M., and Baker, Michelle A.
Abstract:: Biogeochemical reactions associated with stream nitrogen cycling, such as nitrification and denitrification, can be strongly controlled by water and solute residence times in the hyporheic zone (HZ). We used a whole‐stream steady state ¹⁵N‐labeled nitrate (¹⁵NO₃⁻) and conservative tracer (Cl⁻) addition to investigate the spatial and temporal physiochemical conditions controlling...

Labile dissolved organic carbon supply limits hyporheic denitrification

Creator:: Zarnetske, Jay P., Haggerty, Roy, Wondzell, Steven M., and Baker, Michelle A.
Abstract:: We used an in situ steady state ¹⁵N-labeled nitrate (¹⁵NO₃⁻) and acetate (AcO⁻) well-to-wells injection experiment to determine how the availability of labile dissolved organic carbon (DOC) as AcO⁻ influences microbial denitrification in the hyporheic zone of an upland (third-order) agricultural stream. The experimental wells receiving conservative (Cl⁻ and Br)...

Resazurin as a “smart” tracer for quantifying metabolically active transient storage in stream ecosystems

Creator:: Haggerty, Roy, Martí, Eugénia, Argerich, Alba, von Schiller, Daniel, and Grimm, Nancy B.
Abstract:: We propose the experimental use of resazurin (Raz) and develop a metabolically active transient storage (MATS) model to include processes that may provide additional information on transient storage from a biogeochemical perspective in stream ecosystems. Raz is a phenoxazine compound that reduces irreversibly to resorufin (Rru) in the presence of...

Abstract:: We investigated the response of hyporheic exchange flow (HEF) to wood removal in a small, low-gradient, gravel bed stream in southeast Alaska using a series of groundwater models built to simulate HEF for the initial conditions immediately after wood removal and 1 month, 2 years, 4 years, and 16 years...
