Increasing salt production and use is shifting the natural balances of salt ions across Earth
systems, causing interrelated effects across biophysical systems collectively known as …

Catchments, generally understood as the drainage areas of low‐order streams, are often
regarded as closed hydrologic entities; that is, precipitation (P) minus evapotranspiration …

Strontium isotope ratios (87Sr/86Sr) are gaining considerable interest as a geolocation tool
and are now widely applied in archaeology, ecology, and forensic research. However, their …

Over geologic timescales, CO2 is emitted from the Earth's interior and is removed from the
atmosphere by silicate rock weathering and organic carbon burial. This balance is thought to …

Characterizing the lithology, age, and physical‐chemical properties of rocks and sediments
in the Earth's upper crust is necessary to fully assess energy, water, and mineral resources …

We have re-assessed the Sr isotopic budget of the modern ocean taking into account the
high erosion rates of volcanic islands, and especially of island arcs, emphasizing important …

Sedimentary rocks cover∼ 73% of the Earth's surface and metamorphic rocks account for
approximately 91% of the crust by volume. Understanding the average behavior and …

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 …

Laterites and bauxites are produced in tropical soils by weathering, which enriches iron (of
laterites) and alumina (of bauxites)—as well as trace elements such as nickel, gold …

Characterizing the elastic properties of carbonate rocks is a crucial parameter in
geotechnical and reservoir engineering. However, these natural materials exhibit a wide …
