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 …

Submarine groundwater discharge (SGD) is a global and well-studied geological process by
which groundwater of varying salinities enters coastal waters. SGD is known to transport …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

In cold regions where soils freeze and thaw annually, the ground surface deforms due to the
density difference between groundwater and ground ice. Here we mapped thaw subsidence …

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 …

Peatland open‐water pools can be net carbon (C) emitters within heterogeneous peatland
ecosystems that are generally net C sinks. However, the intra‐and inter‐regional patterns …

Rapidly, increasing air temperatures across the Arctic are thawing permafrost and exposing
vast quantities of organic carbon, nitrogen, and phosphorus to microbial processing. Shifts in …

Groundwater rich in dissolved methane is often overlooked in the global or regional carbon
cycle. Considering the knowledge gap in understanding the biogeochemical behavior of …

The magnitude of Alaska (AK) inland waters carbon (C) fluxes is likely to change in the
future due to amplified climate warming impacts on the hydrology and biogeochemical …

Lakes are conduits of greenhouse gases to the atmosphere; however, most efflux estimates
for individual lakes are based on extrapolations from a limited number of locations. Within …
