Methane cycling in the carbonate critical zone

A Oberhelman, JB Martin, MK Flint - Science of The Total Environment, 2023 - Elsevier
The carbonate critical zone (CZ) is characterized by extensive groundwater-surface water
exchange that leads to highly variable redox states of groundwater. Changes in redox …

Groundwater–surface-water interactions: current research directions

ST Larned, MN Gooseff, AI Packman… - Freshwater …, 2015 - journals.uchicago.edu

River Corridor Sources Dominate CO2 Emissions From a Lowland River Network

L Kirk, MJ Cohen - Journal of Geophysical Research …, 2023 - Wiley Online Library
Rivers and streams are control points for CO2 emission to the air (fCO2), with emission rates
often exceeding internal metabolism (net ecosystem production, NEP). The difference is …

Climate control of decadal-scale increases in apparent ages of eogenetic karst spring water

JB Martin, MJ Kurz, MB Khadka - Journal of Hydrology, 2016 - Elsevier
Water quantity and quality in karst aquifers may depend on decadal-scale variations in
recharge or withdrawal, which we hypothesize could be assessed through time-series …

Synoptic estimates of diffuse groundwater seepage to a spring-fed karst river at high spatial resolution using an automated radon measurement technique

MB Khadka, JB Martin, MJ Kurz - Journal of Hydrology, 2017 - Elsevier
Groundwater (GW) seepage can provide a major source of water, solutes, and contaminants
to rivers, but identifying magnitudes, directions and locations of seepage is complicated by …

Hydraulic effects on nitrogen removal in a tidal spring‐fed river

RT Hensley, MJ Cohen… - Water Resources …, 2015 - Wiley Online Library
Hydraulic properties such as stage and residence time are important controls on riverine N
