A Robust, Low‐Cost Conductance Sensor for High Resolution Real‐Time Monitoring of Streambed Pore Water Dynamics

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The groundwater—surface‐water interface is an important regulator of many biogeochemical processes along river corridors. One of the main drivers of these processes is the pore water travel time along hyporheic flow paths. However, our understanding and ability to predict the spatial‐temporal dynamics of subsurface travel times are limited ...

Flushing of Subsurface Soil Nitrate as the Primary Cause of Increased Stream Nitrate During Storm Events

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract The export flux of nitrate from forested catchments via streams typically increases during storms due to simultaneous increases in the nitrate concentration and flow rate. Potential nitrate sources responsible for this increase include rainwater and soil nitrate.

Subglacial Lake Discharge Affects the Age and Concentration Distribution of Dissolved Organic Carbon in Ross Sea Surface Waters

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract The Ross Sea continental shelf plays a key role in the global carbon cycle. However, the sources and cycling of dissolved organic carbon (DOC) in the region are poorly understood. Here, we determined the radiocarbon (14C) and stable carbon isotope (13C) contents of DOC in addition to those of dissolved inorganic carbon (DIC) in the Little ...

Democratizing Hydroclimate Science for Just and Resilient Futures

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Hydroclimatic extremes are intensifying, escalating risks to ecosystems, infrastructure, and vulnerable communities. Rapid technological innovation and scientific discovery offer powerful tools to address these challenges, yet a gap remains between hydroclimate knowledge production and its use in decision‐making.
