| It conceals a multitude of information about temperature, solar radiation, greenhouse gases and precipitation. The group of researchers has specialized in the measurement of what are known as cosmogenic radioisotopes. |
| Age-control for former ice margins will be based on cosmogenic surface exposure dating of till sheets of purportedly different ages. |
| It is formed in the upper atmosphere by cosmogenic rays coming from the sun. |
| Many of these radionuclides exist only in trace amounts in nature, including all cosmogenic nuclides. |
| Surface exposure dating with cosmogenic nuclides is a valuable method for absolute dating of landforms as well as for constraining rates of landscape evolution. |
| As part of this effort, papers on OSL dating and cosmogenic radionuclide dating were published this year. |
