Laminated Sediments in Swamp Lake, California

湖泊的沉积层序为解释古气候史提供了强有力的工具。这些沉积物通常含有古气候和古生态变化的高分辨率记录。拥有这样记录的湖泊在北美西部是罕见的。该SGER奖将侧重于从加利福尼亚州约塞米蒂国家公园的层状沉积物湖泊中提取沉积物岩心。这样一个核心的成功检索具有将过去15000年的陆地、海洋和生态历史与区域气候变化联系起来的巨大潜力

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.***
