Implications of the riverine response to enhanced weathering for CO2 removal in the UK

Autor: Harrington, KJ, Hilton, RG, Henderson, GM

Enhanced silicate weathering, the application of crushed calcium and magnesium-rich rocks to arable cropland, has been proposed as a potential negative emissions technology for the drawdown of atmospheric CO2. Previous estimates have suggested that e

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a ∼9‰ increase during the Cenozoic interpreted as reflecting either a change in continental silicate weathering rate or weathering feedback strength, associated with t

Geomorphic control on the δ15N of mountain forest

Autor: Hilton, RG, Galy, A, West, AJ, Hovius, N, Roberts, GG

Mountain forests are subject to high rates of physical erosion which can export particulate nitrogen from ecosystems. However, the impact of geomorphic processes on nitrogen budgets remains poorly constrained. We have used the elemental and isotopic
