The decrease in the fpe/fce ratio results from the decrease in the cold electron density (erosion of the plasmasphere).
Climate influences the growth of trees and corals, the abundance and geographic distribution of plant and animal species, the chemistry of oceans and lakes, the accumulation of ice in cold regions, and the erosion and deposition of materials on Earth's surface.
A filtering procedure applied to cold and transitional state erosion rates of the Middle and Late Pleistocene yielded peak values between 66 and 77 mm/ka, up to three times higher than the modern rate or the rate of warm-state episodes.
Long-term rates of subaerial and episodic subglacial erosion by predominately cold-based ice cover are determined for tors on weathered plateaus on Cumberland Peninsula.
However, such an accumulated CO2 atmosphere should have been lost since about 4 Gyr ago by solar wind erosion (ion pick up, cold ion outflow), sputtering and photochemical hot atom escape after the martian magnetic dynamo stopped working.
By measuring terrestrial cosmogenic nuclide concentrations in differentially weathered surfaces on a given tor, we reconstruct the complex exposure and erosion history involving recurring cold-based ice cover.
A mere five to seven years later, however, it became clear that the 1960s, far from establishing an American hegemony, had in fact wrought a diffusion of world power and an erosion of the formerly rigid Cold War blocs.
The researchers found that the cold glacial ice protected the mountain from erosion, rather than promoting it.
Measurements of local tube erosion were carried out in a cold pressurized bed with horizontal tubes.
Using innovative new instruments, geochemist Jennifer Lamp and colleagues are measuring erosion of rocks in Antarctica's cold, windy McMurdo Dry Valleys, Earth's best analog to Mars.
