Cosmogenic Radionuclides In Ice Cores From West Antarctica, Zhijie Chen, Thomas Edward Woodruff, Marc W. Caffee
The Summer Undergraduate Research Fellowship (SURF) Symposium
Cosmogenic nuclides such as 10Be and 26Al are formed in the atmosphere by cosmic rays and come down to the ground through snow which became ice in Antarctica. The concentrations of 10Be and 26Al in ice cores can reveal important information about climate change, solar activity and geomagnetic change in the past. They can also be used to date very old ice. Since there is very little 26Al in the ice, its actual concentration is poorly known and the measured results don’t agree with each other. My research is focused on the measurement of the …

Time Scale Creator (TSCreator), a geological chart generator, displays any portion of Earth history including chemo- magneto-, and other aspects. TSCreator is used by many universities, petroleum companies, and international geological surveys. In order to improve the quality of Time Scale Creator, tools were developed to provide users with more friendly graphical user interfaces (GUIs), accurate scaling of specific isotope, internationalization of data input and output, and smart depth scaling in wells to age conversion. To implement such tools, research for algorithm and common methods was basically done by searching articles online and reading posts on forums for Java developers. …
