Poised at the interface of rivers, ocean, atmosphere and dense human settlement, estuaries are driven by a large array of natural and anthropogenic forces. Long-term study of San Francisco Bay illustrates responses to five common agents of change

In the McMurdo Dry Valleys of Antarctica (MDV), streams are an important source of water and hydrologic connectivity between glaciers and lakes across the valleys, however, these streams only run for a few weeks to a few months out of the year.

Zinc concentrations before and after the implementation of remediation strategies were examined in three sub-watersheds in southwestern Colorado. Three tributaries to the Animas River (Cement Creek, Mineral Creek, and the Upper Animas River) were

Much is still unknown about the current permafrost and hydrological conditions of the Gates of the Arctic National Park and Preserve. This study addresses the question of how thermal and hydrogeologic properties of the subsurface may affect active

Machine learning algorithms are gaining popularity in the hydrologic sciences. These algorithms often require tuning hyperparameters to tailor their performance to a specific purpose. Often these hyperparameters are selected based on prior

The Greenland Ice Sheet (GrIS) rapid mass loss is primarily driven by an increase in meltwater runoff, which highlights the importance of understanding the formation, evolution and impact of meltwater features on the ice sheet. Buried lakes are

In the McMurdo Dry Valleys [MDV], Antarctica, little is known about concentration-discharge (C-q) relationships for biological solutes such as DOC. Because MDV streams are low in organic carbon and experience large diel fluctuations in discharge (q

Groundwater supports streamflow and ecosystems in semi-arid, montane catchments, which are environments considered particularly sensitive to climate change. Despite its importance, the relationship between groundwater and streamflow is not well

Reservoirs are typically considered too young and dynamic to validate paleolimnological analysis (Filstrup et al. 2010). Using biological and mineralogical proxies, three shifts were identified in the history of Possum Kingdom Lake, successfully

Tracer experiments have been used to study the exchanges of channel waters with groundwater in streams and their impacts on ecosystem function and water quality are well documented (Bencala & Walters, 1983; Mulholland et al., 1997). However,
