The role of savannas in the terrestrial Si cycle: A case-study from Lamto, Ivory Coast
TL;DR: In this paper, a steady-state Si cycle was established for a tropical humid savanna (Lamto, Ivory Coast) that developed on a ferruginous soil and is subjected to annual fires.
Journal ArticleDOI
Anthropogenic influences on riverine fluxes of dissolved inorganic carbon to the oceans
TL;DR: In this article, a review summarizes controls on the production of HCO3− from chemical weathering and its transport into river systems, showing that the availability of minerals and weathering agents (carbonic, sulfuric, and nitric acids) in the weathering zone interact to control HCO− production, and water throughput controls HCO-3− transport into rivers.

Quaternary Glacial-Interglacial Climate Cycles in Hawaii
TL;DR: The upper kilometer of the Hawaiian Scientific Drilling Program core consists of lavas that were emplaced subaerially, burying paleosols and were used to construct a ∼330kyr Quaternary climate record, indicating that tropical regions such as Hawaii have responded to the same global climate forcings as have higher latitude areas during at least the past three glacial interglacial cycles.

Covariation of climate and long-term erosion rates across a steep rainfall gradient on the Hawaiian island of Kaua'i
Ken L. Ferrier,J. Taylor Perron,Sujoy Mukhopadhyay,Matt Rosener,Jonathan D. Stock,Kimberly Huppert,Michelle Slosberg +6 more
TL;DR: In this paper, the authors present new measurements of erosion rates over 5 yr to 5 m.y. timescales on the Hawaiian island of Kaua'i, across which mean annual precipitation ranges from 0.5 to 9.5 m/yr.
Journal ArticleDOI
Tropical weathering of the Taconic orogeny as a driver for Ordovician cooling
TL;DR: Swanson-Hysell et al. as mentioned in this paper used the paleomagnetic data from well-dated volcanic rocks in the accreting terranes to constrain Laurentia's position given that the Appalachian margin was at, or equatorward of, the paleolatitude of these terrains.

Global silicate weathering and CO2 consumption rates deduced from the chemistry of large rivers
TL;DR: In this article, newly compiled data on the 60 largest rivers of the world are used to calculate the contribution of main lithologies, rain and atmosphere to river dissolved loads, and the relationship between the chemical weathering rates of silicates and the possible controlling parameters are explored.

The carbonate-silicate geochemical cycle and its effect on atmospheric carbon dioxide over the past 100 million years
TL;DR: In this article, a computer model has been constructed that considers the effects on the CO/sub 2/ level of the atmosphere, and the Ca, Mg, and HCO/sub 3/ levels of the ocean, of the following processes: weathering on the continents of calcite, dolomite, and calcium-and-magnesium-containing silicates; biogenic precipitation and removal of CaCO 3/from the ocean; removal of Mg from the ocean via volcanic-seawater reaction; and the metamorphic-magmatic decarbon

Tectonic forcing of late Cenozoic climate
TL;DR: In particular, tectonically driven increases in chemical weathering may have resulted in a decrease of atmospheric C02 concentration over the past 40 Myr as discussed by the authors. But this was not shown to be the case for the uplift of the Tibetan plateau and positive feedbacks initiated by this event.

Geocarb III: A Revised Model of Atmospheric CO2 over Phanerozoic Time
TL;DR: In this article, the GEOCARB model has been updated with an emphasis on factors affecting CO2 uptake by continental weathering, including the role of plants in chemical weathering and the application of GCMs to study the long-term carbon cycle.

A negative feedback mechanism for the long‐term stabilization of Earth's surface temperature
TL;DR: In this article, it is suggested that the partial pressure of carbon dioxide in the atmosphere is buffered, over geological time scales, by a negative feedback mechanism, in which the rate of weathering of silicate minerals (followed by deposition of carbonate minerals) depends on surface temperature, which in turn depends on the carbon dioxide partial pressure through the greenhouse effect.
