Infragravity (hereafter IG) waves are surface ocean waves with frequencies below those of
wind-generated “short waves”(typically below 0.04 Hz). Here we focus on the most common …

Redox-driven biogeochemical element cycles play a central role in converting organic
matter in aquatic ecosystems. They also perform key functions such as removing nitrate …

Submarine groundwater discharge (SGD) is now recognized as an important process of the
hydrological cycle worldwide and plays a major role as a conveyor of dissolved compounds …

Despite the relevance of submarine groundwater discharge (SGD) for ocean
biogeochemistry, the microbial dimension of SGD remains poorly understood. SGD can …

Intrusion of saltwater into freshwater coastal aquifers poisons an essential resource. Such
intrusions are occurring along coastlines worldwide due largely to the over-pum** of …

Coastal ecosystem is an important zone of mercury (Hg) storage and hotspot of neurotoxic
methylmercury (MMHg) production and bioaccumulation. The releases of Hg from coastal …

Subsurface environments host most of the fresh water on Earth as well as diverse
microorganisms that may constitute a significant part of the biosphere. However, the …

Trace metals in the groundwater of coastal sandy aquifers significantly influence the coastal
ecosystem, yet the spatiotemporal controls of these metals remain unclear. In this paper, we …

The Zetaproteobacteria are a class of bacteria typically associated with marine Fe (II)-
oxidizing environments. First discovered in the hydrothermal vents at Loihi Seamount …

The interplay between mixing and reactive processes plays a pivotal role in a range of
biogeochemical processes controlling the transport, transformation and turnover of chemical …
