A Site-Specific Index Based on Weathering Forms Visible in Central Oxford, UK

open access: yesGeosciences, 2012
The authenticity of much of the stone-work along Queen’s Lane in central Oxford, UK presented an opportunity to produce a photographic survey from which a weathering index could be established.

Enhanced chemical weathering of rocks during the last glacial maximum: a sink for atmospheric CO2? [PDF]

open access: yes, 1999
It has been proposed that increased rates of chemical weathering and the related drawdown of atmospheric CO2 on the continents may have at least partly contributed to the low CO2 concentrations during the last glacial maximum LGM..

Effect of weathering on Surface properties of HDPE-based wood plastic composites [PDF]

open access: yesIranian Journal of Wood and Paper Industries, 2018
In this study, Effect of weathering on Surface properties of HDPE-based wood plastic composites was investigated. The variable factors were titanium dioxide nanoparticles content (0, 1, 2 and 3%), raw material type (heat treated wood and untreated wood ...

WEATHER INDEX- THE BASIS OF WEATHER DERIVATIVES [PDF]

open access: yesAnnals of the University of Oradea: Economic Science, 2011
This paper approaches the subject of Weather Derivatives, more exactly their basic element the weather index. The weather index has two forms, the Heating Degree Day (HDD) and the Cooling Degree Day (CDD). We will try to explain their origin, use and the relationship between the two forms of the index.

Impact of nitrogenous fertilizers on carbonate dissolution in small agricultural catchments: Implications for weathering CO2 uptake at regional and global scales [PDF]

open access: yes, 2008
The goal of this study was to highlight the occurrence of an additional proton-promoted weathering pathway of carbonate rocks in agricultural areas where N-fertilizers are extensively spread, and to estimate its consequences on riverine alkalinity and ...

The optimal drought index for designing weather index insurance

open access: yesEuropean Review of Agricultural Economics, 2020
AbstractClimate change increases the need for better insurance solutions that enable farmers to cope with drought risks. We design weather index insurance using drought indices based on precipitation, soil moisture and evapotranspiration as underlying drought index and compare their risk-reducing potential for winter wheat producers in Eastern Germany.

Modeling the evolution of natural cliffs subject to weathering. 2, Discrete element approach [PDF]

open access: yes, 2011
The evolution of slopes subjected to weathering has been modeled by assuming Mohr-Coulomb behavior and by using a numerical approach based on the discrete element method (DEM).

Geochemical characterisation of mangrove sediments in Tiko (SW, Cameroon, West Africa): Implication for provenance, paleoweathering and sediment maturity

open access: yesSolid Earth Sciences, 2023
Geochemistry was performed on clastic core sediments from the Tiko Mangroves estuary, South western region of Cameroon, to categorise the rock source composition, tectonic setting, past weathering intensity of the source area in relation to past climate ...
