项目摘要

Long-term annual to decadal variability of water supply in the Great Basin region of North America is not well understood. Predictions of water supply and groundwater recharge under future warming scenarios can be improved by providing more accurate representations of past climatic changes derived from multi-century-long tree-ring records. Latewood-width and false-ring chronologies have been linked to summertime precipitation, and therefore can provide a record of warm-season moisture over several centuries. This project will exploit a unique potential for reconstructing past variability of the North American Monsoon System (NAMS), one of the key mechanisms for warm-season moisture delivery to the southern Great Basin. New ring-width chronologies combined with anatomical and stable isotopic analyses of conifer species in southern Nevada will be used to reconstruct the northern extension of the NAMS. Cellular-level dendroclimatology is an evolving area of research, and detailed studies of wood formation will complement existing projects in the NAMS region. The project will help clarify the connection between summertime circulation patterns and the El Niño Southern Oscillation (ENSO), as well as the contribution of seasonal moisture regimes during prolonged drought episodes. Expected research results will refine predictions of future differences in water availability between the American Southwest, the Great Basin/Mojave Deserts, and the Four-Corners Region.This research is motivated by the pressing need to quantify the environmental controls of wood formation and the mechanisms underlying dendroclimatic proxies. The project, a collaboration between the University of Nevada, Reno, and the Université du Québec à Chicoutimi, builds on state-of-the-art instrumental transects recently established across two mountain ranges in the Great Basin. Specific research goals are: (1) to mechanistically determine the climatic drivers for earlywood/latewood and false-ring formation in populations of ponderosa pine located at the northwestern limit of the NAMS; and (2) to reconstruct summer monsoon influences on tree growth in this NAMS boundary region as an index of NAMS extension, and its interannual variability, over the past few centuries. Field sampling will take place in the Sheep Range, where the "Nevada Climate-ecohydrological Assessment Network" (NevCAN) provides measurements of atmospheric, pedologic, and vegetational variables along a valley-to-mountain-top transect. Detailed calibration of ponderosa pine tree-ring records will be achieved by combining wood anatomical measurements with stable isotopic analyses of oxygen and carbon from tree rings. Stable oxygen isotopes will also be measured from soil water, atmospheric water vapor, and precipitation to better calibrate the tree ring isotope measurements. Funding supports training of a postdoctoral researcher and a graduate student. The research results will be integrated into graduate and undergraduate level courses at the University of Nevada, Reno, a campus whose student population is constantly increasing in number and diversity.
北美大盆地地区水供应的长期年度至十年变化还没有得到很好的理解。通过提供来自多世纪之久的树木年轮记录的过去气候变化的更准确的描述,可以改善未来变暖情景下的供水和地下水补给预测。晚材宽度和假年轮年表与夏季降水有关,因此可以提供几个世纪以来暖季湿度的记录。该项目将利用重建北美季风系统(NAMS)的过去变化的独特潜力,这是暖季水分输送到南部大盆地的关键机制之一。新的年轮宽度年表结合解剖和稳定同位素分析的针叶树种在内华达州南部将被用来重建北方延伸的NAMS。细胞层次的树木气候学是一个不断发展的研究领域,对木材形成的详细研究将补充NAMS地区的现有项目。该项目将有助于澄清夏季环流模式与厄尔尼诺/南方涛动之间的联系,以及在长期干旱期间季节性湿度状况的作用。预期的研究结果将完善预测未来的差异,美国西南部,大盆地/莫哈韦沙漠,和四角Region.This研究的动机是迫切需要量化的木材形成的环境控制和机制的树木气候代理之间的水资源。该项目是内华达州大学、里诺大学和魁北克大学-希库蒂米分校之间的合作项目,其基础是最近在大盆地的两个山脉上建立的最先进的仪器样带。具体的研究目标是:(1)从机制上确定位于NAMS西北边界的黄松种群早材/晚材和假年轮形成的气候驱动因素;(2)重建夏季风对该NAMS边界区域树木生长的影响,作为NAMS扩展及其年际变化的指标,在过去的几个世纪里。实地采样将在绵羊岭进行,“内华达州气候-生态水文评估网络”(NevCAN)提供沿沿着山谷至山顶样带的大气、土壤和植被变量的测量结果。通过结合木材解剖测量和树木年轮中氧和碳的稳定同位素分析,将实现对黄松年轮记录的详细校准。还将从土壤水、大气水蒸气和降水中测量稳定的氧同位素,以更好地校准树木年轮同位素测量。资金用于培训一名博士后研究员和一名研究生。研究成果将被整合到内华达州大学里诺分校的研究生和本科生课程中,该校区的学生人数和多样性不断增加。
