Collaborative Research: Ideal Paleoclimate Studies on Lake Victoria

9304962 Kelts 该奖项支持在东非湖泊国际十年 (IDEAL) 的支持下对维多利亚湖进行古环境调查。 将进行地震反射和侧扫声纳勘测，以描绘现代沉积环境，确定以前的低位海岸线，定位和测量厚沉积层序，并确定有希望恢复 20 米沉积物岩心的岩心位置。 主要目标是重建维多利亚湖及其周边地区过去 15,000 年的详细环境和气候历史，并在显示十年和一个世纪规模的快速气候变化的区域和全球站点网络中比较该记录。 这项工作将为维多利亚湖系统对气候变化的响应和敏感性提供按时间顺序排列的稳健、高分辨率、多代理绘图。 这项工作将与非洲科学界密切合作进行。 ***

9304962 Kelts This award supports a paleoenvironmental investigation of Lake Victoria under the auspices of the International Decade for the East African Lakes (IDEAL). A seismic reflection and side-scan sonar survey will be conducted to delineate modern sedimentary environments, determine previous lowstand shorelines, locate and measure thick sedimentary sequences, and identify promising core sites for the recovery of 20 meter sediment cores. The primary objective is to reconstruct a detailed environmental and climatic history of Lake Victoria and its environs over the last 15,000 years, and compare that record within the regional and global network of sites showing decadal and century-scale rapid climate change. This work will provide a chronologically robust, high resolution, multi-proxy mapping of the Lake Victoria system's response and sensitivity to climate variation. This work will be undertaken in close collaboration with the African scientific community. ***
