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

open access: yes, 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.

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

open access: yes, 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

open access: yesRevista 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.

An investigation of the basement complex aquifer system in Lofa county, Liberia, for the purpose of siting boreholes [PDF]

open access: yes, 2014
Liberia is recovering from a 14 year civil war and only 51% of the rural population has access to safe drinking water. Little hydrogeological knowledge survives in Liberia, increasing the difficulty in successfully siting new boreholes.

Influence of variables related to soil weathering on the geomechanical performance of tropical soils

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
This paper presents an experimental and analytical investigation of the influence of variables related to soil weathering on the geomechanical performance of sand-silt mixtures containing lateritic soils, i.e.

Organic carbon transport and C/N ratio variations in a large tropical river: Godavari as a case study, India [PDF]

open access: yes, 2005
This study gives an insight into the source of organic carbon and nitrogen in the Godavari river and its tributaries, the yield of organic carbon from the catchment, seasonal variability in their concentration and the ultimate flux of organic and ...

Temperature and Farm Labor in Nigeria

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

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

open access: yesGeophysical 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]

open access: yesOceanography, 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 ...
