High-Resoltuion Paleoclimatic Studies of Lake Turkana, Kenya

东非的古气候历史鲜为人知。 该地区的大陆裂谷作用产生了一系列大型 跨越许多气候系统的湖泊。 如果显示这些湖泊 包含有用的古气候记录，那么重要的是 关于地球气候历史的信息 得到了 本研究的目的是评估 肯尼亚图尔卡纳湖古气候潜力 重建。 这个湖里的沉积物正在积聚 以高速率，通常以反映年度周期的叠层 生产力和沉淀。 故湖有 重建气候历史的潜力 这一地区在过去5000年的年度到世纪的时间尺度上 年 这项研究很重要，因为它将提供一个高 研究气候过程的高分辨率气候记录 和改变

The history of paleoclimate in East Africa is poorly known. Continental rifting in this region has produced a series of large lakes that span many climate regimes. If these lakes are shown to contain useful paleoclimate records, then much important information about the history of earth's climate could be obtained. The purpose of this research is to evaluate the potential of Lake Turkana, Kenya, for paleoclimate reconstructions. Sediments in this lake are accumulating at high rates, often in laminations that reflect the annual cycle of productivity and sedimentation. Thus the lake has the potential of allowing reconstruction of the history of climate in this region on annual to century time scales for the last 5000 years. This research is important because it will provide a high resolution climate record from which to study climate processes and change.
