The sedimentary sequence from lakes containing annual laminations provides a powerful tool for the interpretation of paleoclimate history. These sediments often contain a high resolutiol record of paleoclimate and paleoecological change. Lakes containing such a record are rare in western North America. This SGER award will focus on the retrieval of a sediment core from a lake with laminated sediments in Yosemite National Park, California. The successful retrieval of such a core has great potential for linking terrestrial, marine and ecological histories with regional climate variations over the last 15,000 years.***

含有年度纹层的湖泊的沉积序列为解释古气候历史提供了强有力的工具。这些沉积物往往包含高分辨率的古气候和古生态变化记录。包含这种记录的湖泊在北美西部很少见。该SGER奖将集中于从加利福尼亚州约塞米蒂国家公园的一个湖泊中提取沉积物岩芯。成功地取回这样一个岩芯具有巨大的潜力，可以将陆地、海洋和生态历史与过去15,000年来的区域气候变化联系起来。
