Terrestrial and fluvial carbon fluxes in a tropical watershed: Nyong basin, Cameroon [PDF]

, 2009
The Nyong watershed, with an area of 27 800 km2 and a mean annual discharge of 390 m3 s−1, is the second largest river in Cameroon. The Nyong watershed serves as an outstanding study area for the examination of carbon fluxes in humid tropical ...

Genesis and transformation of basic rock-derived soils with shiny ped faces under tropical conditions

Revista Brasileira de Ciência do Solo, 2022
Soil evolves in landscapes in a natural process in which soil properties are gradually transformed. However, the transformation of argic to ferralic horizons in basic rock-derived soils under tropical conditions is poorly understood.

Iron and phosphorus cycling in deep saprolite, Luquillo Mountains, Puerto Rico [PDF]

, 2010
Rapid weathering and erosion rates in mountainous tropical watersheds lead to highly variable soil and saprolite thicknesses which in turn impact nutrient fluxes and biological populations.

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Tectonics Modulated Long‐Term Weathering Inputs From the East Asian Continent and Tropical Island Arc to the South China Sea Since the Late Oligocene

Geophysical Research Letters
The chemical weathering of Earth's silicate rocks regulates the global climate. However, the exact role of continental weathering with orogenic building and island arc weathering with arc‐continent collisions remains unclear.

Was the Late Paleocene-Early Eocene Hot Because Earth Was Flat? An Ocean Lithium Isotope View of Mountain Building, Continental Weathering, Carbon Dioxide, and Earth's Cenozoic Climate [PDF]

Oceanography, 2014
Hothouse climates in Earth's geologic past, such as the Eocene epoch, are thought to have been caused by the release of large amounts of carbon dioxide and/or methane, which had been stored as carbon in biogenic gases and organic matter in sediments, to ...

Natural weathering on coated tropical woods

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Teak and pine are common wood species in Indonesia. The purpose of this research is to evaluate the performance of the coating layer in these wood species after six months natural weathering. The durability on natural weathering is evaluated due to microbial disfigurement (fungi or algae), checking and cracking, whereas ...
