Sediment archives in the terrestrial and marine realm are regularly analyzed to infer
changes in climate, tectonic, or anthropogenic boundary conditions of the past. However …

Publisher Summary This chapter summarizes the recent applications of U-series nuclides to
study weathering and river transport. The chapter focuses on the determination of time …

We report Li isotope composition (δ 7 Li) of river-borne dissolved and solid material in the
largest River system on Earth, the Amazon River basin, to characterize Li isotope …

Residual solid products of erosion display a wide range of size, density, shape, mineralogy,
and chemical composition and are hydrodynamically sorted in large river channels during …

Mobilization of Arctic permafrost carbon is expected to increase with warming-induced
thawing. However, this effect is challenging to assess due to the diverse processes …

The correlation between chemical weathering fluxes and denudation rates suggests that
tectonic activity can force variations in atmospheric pCO 2 by modulating weathering fluxes …

In order to reveal particulate organic carbon (POC) source and mode of transport in the
largest river basin on Earth, we sampled the main sediment-laden tributaries of the Amazon …

The interplay between the hydrologic processes that supply, store, and route water in
catchment systems and the chemical weathering reactions that add and remove solutes acts …

We use cosmogenic nuclide-derived denudation rates from in situ–produced 10Be in river
sediment to determine sediment production rates for the central Amazon River and its major …

The oxidation of organic carbon contained within sedimentary rocks (“petrogenic” carbon, or
hereafter OCpetro) emits nearly as much CO2 as is released by volcanism, thereby playing …
