By 1931 it had long been suspected that there were differences in the chemical properties of
the isotopes of an element, but it was the discovery of the rare heavy isotopes of the light …

Dimethyl sulphide (DMS) is the dominant sulphur gas found in surface marine waters and
there is compelling evidence that it is formed biologically in these environments. In all areas …

Salinity is a fundamental property of watermasses that is useful in paleoenvironmental and
paleoecological studies, yet the theory of application of geochemical proxies to paleosalinity …

The interdisciplinary nature of limnology requires lucid and well-integrated coverage of

The extent of marine influence on the Paleogene Bohai Bay Basin in northeastern China,
which accumulated mainly continental (eg, fluvial and lacustrine) facies, remains under …

XRF core scanners, with their rapid and non-destructive analytical capability, have now
been used for two decades in the analysis of marine sediments. Initially they were used to …

Sulfate is taken up by algae and plants and then reduced and incorporated into organosulfur
compounds. Marine algae produce dimethylsulfonium propionate (DMSP), which has an …

The observed stability of Earth's climate over millions of years is thought to depend on the
