Silicate rock weathering and atmospheric/soil CO2 uptake in the Amazon basin estimated from river water geochemistry: seasonal and spatial variations [PDF]

open access: yes, 2003
Using the data of the CAMREX project (1982–1984) on the water geochemistry of the Amazon river and its main tributaries, it was possible to assess the silicate rock weathering processes and the associated consumption of atmospheric/soil CO2, taking into

A revised model of global silicate weathering considering the influence of vegetation cover on erosion rate [PDF]

open access: yesGeoscientific Model Development
Silicate weathering, which is of great importance in regulating the global carbon cycle, has been found to be affected by complicated factors, including climate, tectonics and vegetation. However, the exact transfer function between these factors and the

Atmospheric CO2 consumption by continental erosion : present-day controls and implications for the last glacial maximum [PDF]

open access: yes, 1998
The export of carbon from land to sea by rivers represents a major link in the global carbon cycle. For all principal carbon forms, the main factors that control the present-day fluxes at the global scale have been determined in order to establish global

Sensitivity of the global carbonate weathering carbon-sink flux to climate and land-use changes [PDF]

open access: yes, 2019
The response of carbonate weathering carbon-sink flux (CCSF) to its environmental drivers is still not well understood on the global scale. This hinders understanding of the terrestrial carbon cycle.

The importance of terrestrial weathering changes in multimillennial recovery of the global carbon cycle: a two-dimensional perspective [PDF]

open access: yesEarth System Dynamics, 2017
In this paper, we describe the development and application of a new spatially explicit weathering scheme within the University of Victoria Earth System Climate Model (UVic ESCM).

Old carbon contributes to aquatic emissions of carbon dioxide in the Amazon [PDF]

open access: yes, 2014
Knowing the rate at which carbon is cycled is crucial to understanding the dynamics of carbon transfer pathways. Recent technical developments now support measurement of the <sup>14</sup>C age of evaded CO<sub>2</sub> from fluvial

Variation of Soil Aggregation along the Weathering Gradient: Comparison of Grain Size Distribution under Different Disruptive Forces. [PDF]

open access: yesPLoS ONE, 2016
The formation and stabilization of soil aggregates play a key role in soil functions. To date, few studies have been performed on the variation of soil aggregation with increasing soil weathering degree. Here, soil aggregation and its influencing factors
