Association of runoff risk with private well contamination in a fractured dolostone aquifer

Journal of Environmental Quality, Volume 55, Issue 6, November/December 2026.
Abstract In the United States, private well owners are responsible for monitoring and maintaining their drinking water but have little control over neighboring contamination sources and limited information about daily water quality. Potential for rapid contamination in karst settings exacerbates the challenge.

Titan’s refractory core evolution: Implications for organics in its subsurface ocean

International audienceAs an organic-rich world with a subsurface ocean, Titan is an object of great astrobiological interest. However, geological signs of surface-subsurface exchange are limited, and Titan’s thick icy crust may significantly impede ...

Terrestrial inputs and in‐lake processes shape dissolved organic matter along a permafrost gradient

Limnology and Oceanography, Volume 71, Issue 11, November 2026.
Abstract Northern permafrost landscapes store large amounts of organic carbon that can enter lakes as dissolved organic matter (DOM), but links among shoreline terrestrial sources, lake‐water DOM composition, and catchment configuration remain uncertain in low‐precipitation Shield landscapes. We combined shoreline soil‐porewater and lake‐water sampling

Hidden subsurface suspended sediment export from Greenland's marine‐terminating glaciers

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Runoff and calved ice volumes from the Greenland Ice Sheet are well constrained, but quantifying the associated suspended sediment flux remains challenging. Here we present near‐terminus observations from three glacierized fjords in southeast Greenland, combining full‐depth turbidity profiles and current velocity from summer 2024 to evaluate ...

Contrasting associations of sea‐ice meltwater and meteoric water with nitrogen uptake patterns in the summer Cosmonaut Sea, Antarctica

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Nitrogen uptake by phytoplankton influences Southern Ocean productivity and carbon export, but how source‐resolved meltwater is associated with nitrate and ammonium use remains unclear. Here, 15N tracer incubations and a δ18O‐salinity mixing model were combined to examine nitrogen uptake in the early‐summer Cosmonaut Sea.

Invasive saltmarsh removal linked to reduced geomorphic resilience of a tidal flat

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Large‐scale removal of the invasive saltmarsh plant Spartina alterniflora has become a major restoration intervention along China's coast, yet its biogeomorphic consequences remain unclear. Using pre‐removal in situ sediment dynamics observations and five annual topographic surveys spanning removal, we show that S.
