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, these experiments are much more difficult in larger rivers due to higher flows...

Reduced human activity associated with lockdown protocols due to the Covid-19 pandemic have temporarily changed carbon emission patterns of urban ecosystems globally. Understanding how these changes anthropogenic activities contribute to the urban emissions offer the opportunity to better understand the carbon dynamics outside pandemic conditions. Here we explore how the...

STULTS , John 1 1 CU Boulder The last decade of oil and gas exploration in the United States has been characterized by a sharp increase in the amount of oil and gas acquired from low-permeability shale formations. These low-permeability formations are non-traditional oil and gas reservoirs, which require hydraulic...
