Radon (222 Rn) is a colourless, odourless, inert, and radioactive noble gas (t 1/2= 3.8 days)
that emanates from rocks and soils as a result of the alpha decay of its parent, radium (226 …

The naturally occurring isotope radon-222 (222 Rn) is widely employed as a tracer for
groundwater discharge to lakes, lagoons, rivers, estuaries, and coastal oceans. Owing to the …

Groundwater is projected to become an increasing source of freshwater and nutrients to the
Arctic Ocean as permafrost thaws, yet few studies have quantified groundwater inputs to …

Lake eutrophication is a large and growing problem in many parts of the world, commonly
due to anthropogenic sources of nutrients. Improved quantification of nutrient inputs is …

Lateral CH4 inputs to Arctic lakes through groundwater discharge could be substantial and
constitute an important pathway that links CH4 production in thawing permafrost to …

Quantifying groundwater discharge remains a challenge due to its large temporal and
spatial variability. Here, we quantify groundwater discharge into a small estuary using radon …

Many coal mining subsidence lakes have formed in eastern China due to underground coal
mining. Lacustrine groundwater discharge (LGD) is of great importance to the hydrological …

More than 75 years after its introduction, the seepage meter remains the only device for
directly quantifying exchange across the sediment-water interface between groundwater …

Groundwater seepage influences the temperature of streams and rivers by providing a
relatively cool input in summer and warm input in winter. Because of this, groundwater …

Identifying interactions among river water, groundwater and salt lake brine is important for
sustainable exploitation of brine mineral resources. In this study, we investigated the water …
