In addition, marine sediment archives offer opportunities for application of multiple proxies representing different climatic and oceanographic systems. Click the View full text link to bypass dynamically loaded article content. This is caused by a number of factors, including variations in solar radiation, magnetic storms, and internal geophysical factors. Precision and accuracy in glacial geology. It gives an Exposure Age : that is, how long the rock has been exposed to cosmic radiation. Photo of the Day. If this is not possible then the cores should be covered in plastic wrap with all of the air removed. The radiation emanates from radioactive grains within the sediment, such as zircons.
