The increasing appreciation of the small-scale (sub-mm) heterogeneity of biogeochemical
processes in sediments, wetlands and soils has led to the development of several methods …

Although recent studies indicate that fluvial systems can be accumulation areas for
microplastics (MPs), the common perception still treats rivers and streams primarily as pure …

The microbial community composition and biogeochemical dynamics of coastal permeable
(sand) sediments differs from cohesive (mud) sediments. Tide-and wave-driven …

The hyporheic zone, defined by shallow subsurface pathways through river beds and banks
beginning and ending at the river, is an integral and unique component of fluvial systems. It …

In eutrophic lakes, the decay of settled algal biomass generates organic carbon and
consumes oxygen, favoring sediment nitrogen loss via denitrification. However, persistent …

Recent observations reveal a paradox of anaerobic respiration occurring in seemingly oxic‐
saturated sediments. Here we demonstrate a residence time‐based explanation for this …

Hyporheic exchange induced by periodic river fluctuations leads to important
biogeochemical processes, particularly nitrogen cycling, in riparian zones (RZs) where …

The balance between estuarine denitrification and dissimilatory nitrate reduction to
ammonium (DNRA) is critical for determining nitrogen loads received by oceans from inland …

The hyporheic zone is the interface beneath and adjacent to streams and rivers where
surface water and groundwater interact. The hyporheic zone presents unique conditions for …

Permeable (sandy) sediments cover half of the continental margin and are major regulators
of oceanic carbon cycling. The microbial communities within these highly dynamic …
