The global sediment cycle is a fundamental feature of the Earth system, balancing
competing factors such as orogeny, physical–chemical erosion and human action. In this …

Soil organic matter (SOM) anchors global terrestrial productivity and food and fiber supply.
SOM retains water and soil nutrients and stores more global carbon than do plants and the …

Rivers support indispensable ecological functions and human health and infrastructure. Yet
limited river sampling hinders our understanding of consequential changes to river systems …

The element silicon (Si) is required for the growth of silicified organisms in marine
environments, such as diatoms. These organisms consume vast amounts of Si together with …

Assessments of the implications of soil erosion require quantification of soil erosion rates
(SE) and sediment yield (SSY) at regional scales under present and future climate and land …

Here we provide global estimates of the seasonal flux of sediment, on a river-by-river basis,
under modern and prehuman conditions. Humans have simultaneously increased the …

Deltas are resource rich, low-lying areas where vulnerability toflooding is exacerbated by
natural and anthropogenically induced subsidence and geocentric sea-level rise …

Much work has been undertaken quantifying the abundance of phyllosilicate clay minerals
in soils, sediments and rocks of Earth's crust. However, no detailed global compilation of …

Data and computer simulations are reviewed to help better define the timing and magnitude
of human influence on sediment flux—the Anthropocene epoch. Impacts on the Earth …

Land–ocean transfer of sediment by rivers is a key pathway for material transfer on Earth.
Contemporary data on the sediment loads of rivers provide clear evidence of significant …
