2003) studied long-term weathering rates in the Sierra Nevada (California) and Puerto Rico, using geochemical mass balances and estimates of physical denudation rates based on cosmogenic
The resulting changes in solar radiation changes the temperature and this may be detected by changes in the ratios of cosmogenic
isotopes in ice cores.

Isotopes, and Theological Implications," 59:2, 136, J 2007.
About the time metaphysics was cast from the charmed circle of academic philosophy into the outer shadows where it has lurked since, American founder of Pragmatism Peirce (1839-1914) was proposing a reconstruction of metaphysics from an ontological or religious endeavor into a scientific or cosmogenic
nuclide chronology of millennial-scale glacial advances during O-isotope stage 2 in Patagonia.
Charles Jencks, pictured, was born in Baltimore in 1939 and now designs landscape, sculpture and writes on cosmogenic
On the other hand, the kind of cosmogenic
art that interests me engages the mind and makes claim on deep truths that are revealed at a certain time and place.
nuclide insights on the interaction between local ice caps and Laurentide Ice in northern Labrador
Accelerator mass spectrometry measurements of cosmogenic
The naturally-derived nuclides include uranium and thorium decay series nuclides that, because of their long half-lives, are found ubiquitously throughout the environment and cosmogenic
radionuclides, such as carbon-14 and tritium (3H), which are produced in the upper atmosphere.
Breakthroughs in new techniques are described in Section 1, including detrital zircon geochronology, cosmogenic
nuclide dating, magnetostratigraphy, 3-D seismic, and basin modelling.
As an alternative to magnetization, changes in geomagnetic intensity can be reconstructed from the production of cosmogenic
A proxy for sunspot activity prior to the start of telescope observations in 1610 can be reconstructed from the abundance of cosmogenic
(10) Be in ice cores from Antarctica and Greenland (Miletsky et al.
In his research, Muscheler worked to reconstruct previous changes in solar activity by studying how cosmogenic
isotopes, for example of beryllium-10 and carbon-14, have been stored in both ice cores and annual rings in trees.
There are several age estimations from mineral samples (using thermoluminescence, optically stimulated luminescence and cosmogenic
