A climate signal the global distribution copper deposits
2015/5/25
Climate helps drive the erosion process that exposes economically valuable copper deposits and shapes the pattern of their global distribution, according to a new study from researchers at the Univers...
Extracting a common high frequency signal from Northern Quebec black spruce tree-rings with a Bayesian hierarchical model
Northern Quebec black spruce tree-rings Bayesian hierarchical model
2009/12/3
One basic premise of dendroclimatology is that tree rings can be viewed as climate proxies, i.e. rings are assumed to contain some hidden information about past climate. From a statistical perspective...
Climate and CO2 modulate the C3/C4 balance and δ13C signal in simulated vegetation
Climate and CO2 modulate δ13C signal C3/C4 balance
2009/12/3
Climate and atmospheric CO2 effects on the balance between C3 and C4 plants have received conflicting interpretations based on the analysis of carbon isotopic fractionation (δ13C) in sediments. But, c...
Photolysis imprint in the nitrate stable isotope signal in snow and atmosphere of East Antarctica and implications for reactive nitrogen cycling
nitrate stable isotope signal snow atmosphere East Antarctica reactive nitrogen cycling
2009/11/19
The nitrogen (δ15N) and triple oxygen (δ17O and δ18O) isotopic composition of nitrate (NO3−) was measured year-round in the atmosphere and snow pits at Dome C, Antarctica (DC, 75.1° S, 123.3° E)...
