项目摘要

9981488CochranThis three-year award for U.S.-France collaboration in environmental geochemistry involves J. Kirk Cochran of the State University of New York at Stony Brook and Alain Veron of the Centre Europeen de Recherche et d'Enseignement de Geosciences (CEREGE) in Marseilles, France. The investigators will determine the history of input rates and sources of stable lead to coastal areas. Archived samples from salt marshes in the northeastern United States, and from Italy will be analyzed for isotopes of lead to determine their sources. Previous research by the U.S. investigator has established chronologies of accumulation and lead flux for each site. These samples will be complemented by the collection of two cores from salt marshes located in the Rhone Delta in Southern France. Chronologies and stable lead concentrations from these sites will be analyzed at CEREGE. The U.S. investigator brings to this collaboration expertise in geochronology and use of natural radionuclides as tracers. This will be complemented by French expertise in lead isotopes. The project will advance understanding of sources of coastal atmospheric pollution. This award represents the U.S. side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the U.S. investigator to collect samples, work on the analyses of lead, and present a short course in France. The CNRS will support the visits of the French researchers to the United States.

9981488 Cochranthis在环境地球化学方面的三年合作奖涉及纽约州立大学的Stony Brook的J. Kirk Cochran和Marseilles，France Marseilles的Eureopeen de Recherche et d'Enseignement de Geosciences（Cerege）的Europeen de Recherche et d'Enseignement de Enseignement eyopeen de Recherche等人的Alain Veron。调查人员将确定投入率的历史和稳定的稳定来源导致沿海地区。将分析来自美国东北部盐沼的存档样品，并将分析来自意大利的铅的同位素，以确定其来源。美国研究人员的先前研究已经确定了每个站点积累和铅通量的时间表。这些样品将通过位于法国南部Rhone Delta的盐沼中收集的两个核心来补充。这些位点的时间顺序和稳定的铅浓度将在Cerege进行分析。美国的研究者将这种合作学方面的合作知识和使用自然放射性核素作为示踪剂的使用。法国铅同位素方面的专业知识将得到补充。该项目将进一步了解沿海大气污染的来源。该奖项代表了NSF和法国国家科学研究中心（CNRS）的联合提案的美国。 NSF将为美国调查员收集样品，进行铅分析并在法国提供短期课程，以供美国调查员收集样品，从事旅行资金和生活费用。中枢神经系统将支持法国研究人员对美国的访问。
