9316162 Stuiver This award is for support of a two year program to obtain a high- resolution time series of cosmogenic Beryllium-10 (10Be) and Chlorine-36 (36Cl) from two shallow firn cores which have been retrieved from Taylor Dome and upper Taylor Glacier, East Antarctica. The work will complement the ice-core paleoclimate and glaciological studies already underway at Taylor Dome and should contribute to a better understanding of the atmospheric transport and depositional mechanisms of these isotopes. The 10Be and 36Cl time series will help to determine cosmogenic isotope production rates over annual to millennial time periods, which will provide information on solar and geomagnetic variability. ***

9316162 Stuiver该奖项是对一项为期两年的计划的支持，该计划旨在从从东南极泰勒穹顶和上泰勒冰川取回的两个浅积雪岩芯中获取宇宙成因铍-10(10Be)和氯-36(36Cl)的高分辨率时间序列。这项工作将补充泰勒穹顶已经在进行的冰芯古气候和冰川学研究，并应有助于更好地了解这些同位素的大气输送和沉积机制。10Be和36Cl时间序列将有助于确定每年至千年期间的宇宙成因同位素产生率，这将提供有关太阳和地磁变化的信息。***
