Gas exchange across the air–water boundary of streams and rivers is a globally large
biogeochemical flux. Gas exchange depends on the solubility of the gas of interest, the gas …

Expectations for continuous miniaturization in mass spectrometry are not declining for years.
Portable instruments are highly welcome by the industry, science, space agencies, forensic …

The estimation of whole stream metabolism, as determined by photosynthesis and
respiration, is critical to our understanding of carbon cycling and carbon subsidies to aquatic …

Lotic systems are a prominent ecohydrological interface within which complex, coupled
interactions occur between ecological, hydrological, and geochemical processes. This …

Labeling groundwater by injecting an artificial tracer is a standard and widely used method
to study groundwater flow systems. Noble gases dissolved in groundwater are potentially …

Urban groundwater management requires a thorough and robust scientific understanding of
flow and transport processes. 3 H/3 He apparent ages have been shown to efficiently help …

Abstract Surface water (SW)-groundwater (GW) interactions exhibit complex spatial and
temporal patterns often studied using tracers. However, most natural and artificial tracers …

Using continuous injections of helium coupled to in-situ continuous flow membrane inlet
mass spectrometry (CF-MIMS), we mapped the gas exchanges along two low-slope …

Gas exchange across the air–water interface is a key process determining the release of
greenhouse gases from surface waters and a fundamental component of gas dynamics in …

Lower‐order streams (first‐and second‐order) define the initial, landscape‐related,
chemical signature of stream water in catchments. To date, first‐order streams have been …
