International Research Workshop: Peatland Archives of Holocene Climate Variability

泥炭地沉积物构成了全新世气候变化和变率的宝贵档案。这些泥炭地广泛分布在北半球和南半球的中高纬度地区，以及低纬度地区的高海拔地区，包括热带山区。它们的沉积物包含多种微化石、宏观化石、地球化学和稳定同位素的温度和水文代用物，记录对次百年至次年代用气候变化明显敏感。这项拨款将支持于2009年5月举行的国际研讨会，该研讨会将召集36名顶尖研究人员，确定关键的研究需求和优先事项，制定全面的科学议程，以推进泥炭地古气气学，并启动全新世泥炭地记录全球网络的规划。参与者将包括具有泥炭地古气候学、水文学和生物地球化学专业知识的科学家，以及具有建模和统计分析专业知识的古气候学家，以及其他全新世晚期档案（如树木年轮、洞穴主题、湖泊沉积物）。知识价值：研讨会将促进利用泥炭地档案进行古气候研究，并将其与其他高分辨率档案相结合，从而推动全新世古气候学的发展。研讨会产品将包括摘要文章、研究合作，以及向北美（包括美国国家科学基金会）、欧洲和其他地方的科学机构提出的衍生建议。更广泛的影响：研讨会将促进古气候学方面的国际科学合作和协作。至少25%的参与者将来自北美和西欧以外的地区（亚洲、南美、前苏联集团），至少15%的参与者将是早期职业科学家，主要是研究生和博士后。

Sediments of Sphagnum-dominated peatlands constitute a valuable archive of Holocene climate change and variability. These peatlands are broadly distributed at mid to high latitudes in both the Northern and Southern Hemispheres, and at high elevations at lower latitudes, including tropical mountains. Their sediments contain a variety of microfossil, macrofossil, geochemical, and stable-isotope proxies of temperature and hydrology, and records are demonstrably sensitive to subcentennial to subdecadal climate variation.This grant supports an international workshop to take place in May 2009, assembling 36 leading researchers to identify critical research needs and priorities, develop a comprehensive science agenda to advance peatland paleoclimatology, and initiate planning for a global network of Holocene peatland records. Participants will include scientists with expertise in peatland paleoclimatology, hydrology, and biogeochemistry, as well as paleoclimatologists with expertise in modeling, and statistical analysis, and other late Holocene archives (e.g., tree rings, speleothems, lake sediments).Intellectual Merit:The workshop will advance the science of Holocene paleoclimatology by fostering paleoclimate studies using peatland archives and integrating them with other high-resolution archives. Workshop products will include summary articles, research collaborations, and spinoff proposals to scientific agencies in North America (including NSF), Europe, and elsewhere.Broader Impacts:The workshop will foster international scientific cooperation and collaboration in paleoclimatology. At least 25% of the participants will be from outside North America and western Europe (Asia, South America, former Soviet Bloc), and at least 15% of the participants will be early-career scientists, primarily graduate students and post-docs.
