Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

The silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …

Land to ocean transfer of material largely controls the chemical composition of seawater and
the global element cycles. Overall this transfer is dominated by the riverine transport of …

Rare earth element (REE) concentrations and neodymium isotopic composition (ɛNd) are
tracers for ocean circulation and biogeochemistry. Although models suggest that REE …

Over millions of years, the interaction of marine basalt with percolating seawater in low-
temperature ocean floor hydrothermal systems leads to the formation of calcite and …

Abstract Neodymium isotopic compositions (143 Nd/144 Nd or ε Nd) have been used as a
tracer of water masses and lithogenic inputs to the ocean. To further evaluate the …

Before submarine hydrothermal vents were discovered, the 87 Sr/86 Sr record of seawater
was interpreted as a mixture of unradiogenic basaltic and radiogenic granitic continental …

The stable strontium isotope system (δ 88/86 Sr) has recently been suggested to be a
suitable proxy for determining variations in the strength of the marine carbonate system, the …

The exchange of material between particulates and seawater along the continental margins,
a process commonly referred to as boundary exchange, is thought to play a significant role …

The isotopic composition of Phanerozoic marine sediments provides important information
about changes in seawater chemistry. In particular, the radiogenic strontium isotope (87 …
