First reported in the 1960s, offshore freshened groundwater (OFG) has now been
documented in most continental margins around the world. In this review we compile a …

Groundwater Age is the first book of its kind that incorporates and synthesizes the state-of-
the-art knowledge about the business of groundwater dating-including historical …

Atmospheric methane (CH4) concentrations have more than doubled in the past~ 250 yr,
although the sources of this potent greenhouse gas remain poorly constrained. Freshwaters …

In well-studied aquatic systems such as surface waters and groundwater, noble gases are
used extensively as natural tracers to reconstruct palaeoenvironmental conditions, to study …

Despite their great importance in low-temperature geochemistry, diffusion coefficients of
noble gas isotopes in liquid water (D) have been measured only for the major isotopes of …

The 4He/U-Th dating method can be used to estimate the residence time of pore waters in
low-permeable rocks and consolidated sediments, serving as a proxy for sediment …

The release of gas bubbles from lacustrine or oceanic sediments into the overlying water
(ebullition) is a major mechanism for the discharge of biogenic or geogenic gases into the …

To identify reactive processes in diffusion dominated water-saturated systems using
compound-specific isotope analysis (CSIA), the effect of the diffusive transport process on …

In closed-basin lakes, sediment porewater salinity can potentially be used as a conservative
tracer to reconstruct past fluctuations in lake level. However, until now, porewater salinity …

Aquatic sediments represent a key component for understanding CH4 dynamics and
emission to the atmosphere. Once produced in the sediments, CH4 is released either by …
