The CAESAR (Cellular Automaton Evolutionary Slope And River) model is used to simulate the Holocene development of a small upland catchment (4.2 km(2)) and the alluvial fan at its base. The model operates at a 3 m grid ...

Ice-free areas Antarctica reveal a multi-million year history of landscape evolution, but most attention up to now has focused on the Transantarctic Mountains. The Amery Oasis in the northern Prince Charles Mountains borders ...

Human activities have doubled the pre-Industrial supply of reactive nitrogen on Earth, and future rates of increase are expected to accelerate. Yet, little is known about the capacity of the biosphere to buffer elevated ...

Sheep Creek tephra (SCt) consists of inflated, rhyolitic pumice with abundant plagioclase and hornblende, lesser amounts of ferrian ilmenite and magnetite, and trace quantities of basaltic hornblende, augite, quartz, ...

For many years, the classification of forest communities and their associated species from airborne data (primarily aerial photography) has largely been through manual interpretation. With the development of digital imagery, ...

The temperature dependence, dose response and bleaching characteristics of the thermally transferred optically stimulated luminescence (TT-OSL) of sedimentary quartz were studied, in order to assess the potential of the ...

Avulsions are most characteristic of aggrading fluvial systems, but along the Klip River, subhumid eastern South Africa, abandonment and re-establishment of meander belts occurs under conditions of negligible vertical ...
