SGER: Paleoclimatic Research in Lake Titicaca

杜克大学Baker， Paul a .标题：SGER：的的喀喀湖的古气候研究该奖项是为探索性研究（SGER）提供的小额资助。的的喀喀湖（秘鲁/玻利维亚）可能包含了南美洲热带地区第四纪气候变化的最重要的沉积记录。以前对该湖的古气候研究只涉及对浅水岩心的分析。这是因为从湖泊中部部分地区回收沉积物是一项重大任务，需要一艘足够大的船只来应对湖泊的恶劣海况。作为这项研究的一部分，还应进行广泛的地震反射剖面分析，以帮助选择岩心地点，并作为识别断层和沉积相的一种手段。在为到的的喀喀湖的重大考察申请资金之前，与秘鲁和玻利维亚的政府官员和科学家进行个人接触，以确保未来研究工作的成功，是适当和谨慎的。该奖项支持前往秘鲁和玻利维亚的旅行，以便：(1)联系政府官员，以获得批准研究游轮的保证；(2)亲自与南美的科学同事沟通，确保他们适当地参与这项研究；(3)确定技术设施和物资的可用性。

Abstract ATM-9414733 Baker, Paul A. Duke University Title: SGER: Paleoclimatic Research in Lake Titicaca This award is in support of a Small Grant for Exploratory Research (SGER). Lake Titicaca (Peru/Bolivia) may contain the most important sedimentary record of Quaternary climatic change in tropical South America. Previous paleoclimatic studies in the lake have only involved analysis of shallow-water cores. This is because the recovery of sediments from central, portions of the lake is a major undertaking, involving a sufficiently large vessel for the rough sea conditions of the lake. Extensive seismic reflection profiling should also be done as part of this study as an aid to core site selection and as a means for identification of hiatuses and sedimentary facies. Prior to requesting funds for a major expedition to Lake Titicaca, it is appropriate and prudent to make personal contact with government officials and scientists in Peru and Bolivia to ensure the success of future research efforts. This award supports travel to Peru and Bolivia in order to: (1) contact government officials to obtain assurances that research cruises will be approved; (2) communicate personally with South American scientific colleagues to ensure that they will be properly involved in this research; and (3) determine the availability of technical facilities and supplies.
