DOI: 10.1016/j.ecss.2018.12.019
Abstract: Abstract As an important component of the hydrological and biogeochemical cycle, porewater discharge represents a significant pathway for releasing chemical solutes into coastal zones, particularly in highly permeable aquifers. In this study, a 222Rn advection-diffusion… read more here.

DOI: 10.1021/acs.est.2c00312
Abstract: The freely dissolved concentration of hydrophobic pollutants in sediment porewater (Cpw) is a critical driver for exposure to aquatic organisms, bioaccumulation, toxicity, and flux across interfaces. In this research, we compared direct porewater extraction and… read more here.

DOI: 10.1021/acs.est.8b05390
Abstract: In flooded soils, soil–water interface (SWI) is the key zone controlling biogeochemical dynamics. Chemical species and concentrations vary greatly at micro- to cm-scales. Techniques able to track these changing element profiles both in space and… read more here.

DOI: 10.1038/s41598-021-02314-y
Abstract: Ecosystem feedbacks in response to ocean acidification can amplify or diminish diel pH oscillations in productive coastal waters. Benthic microalgae generate such oscillations in sediment porewater and here we ask how CO2 enrichment (acidification) of… read more here.
