Abstract ATM-9814063 Johnson, Thomas C. University of Minnesota Title: Climate-sediment Linkages in Lake Malawi, Africa During ENSO This SGER award supports measurements of water temperature profiles and sediment particle flux to the floor of Lake Malawi at the southern end of the East African Rift Valley. It is critical that this be accomplished as the very strong El Nino-Southern Oscillation (ENSO) of 1997-1998 winds down. The project has a severe urgency with regard to being quick response research to a natural phenomenon. Circulation dynamics and sediment trap studies in Lake Malawi will have direct implication for high resolution studies of past climate change in tropical Africa, based on the analysis of varved sediments from Lake Malawi. This work will provide essential baseline information for the IDEAL project.

摘要ATM-9814063约翰逊，托马斯C. 明尼苏达大学题目：ENSO期间非洲马拉维湖的气候-沉积物联系 该SGER奖支持测量东非大裂谷南端马拉维湖的水温剖面和沉积物颗粒通量。 随着1997-1998年非常强烈的厄尔尼诺-南方涛动逐渐减弱，必须做到这一点。 该项目在对自然现象进行快速反应研究方面具有严重的紧迫性。 马拉维湖的环流动力学和沉积物捕集研究将对基于马拉维湖纹状沉积物分析的热带非洲过去气候变化的高分辨率研究产生直接影响。 这项工作将为IDEAL项目提供基本的基线资料。
