CAREER: Integrating Research and Education to Advance the Use of Heat as a Tracer of Surface-Ground Water Interaction at Multiple Spatial and Temporal ScalesL. K. Lautz, State University of New York, College of Environmental Science and ForestryStream-groundwater (SW-GW) interaction is a critical component of a variety of water quality and quantity issues. It has proven difficult to accurately characterize SW-GW interactions, particularly in streams, and they are often ignored due to the challenges of spatial and temporal generalization of point-in-space or -time measurements. There has been a renewed interest in the use of heat as a tracer in hydrologic systems because heat transport has a number of advantages over traditional methods of characterizing SW-GW interaction. Despite recent technological and analytical developments in the application of heat as a tracer in hydrologic systems, much remains to be learned. The major objective of this proposal is to integrate research and teaching to advance the application of heat transport theory to characterize water flux between streams and groundwater and to relate those fluxes to changes in water quality over a variety of spatial and temporal scales. Proposed work includes: (1) Linking field observations of temperature with modeling to quantify SW-GW flux rates over different scales and (2) linking SW-GW interaction to geochemical variability. Research innovations in this proposal include scaling-up observations while maintaining fine-scale spatial resolution by using fiber optic distributed temperature sensor technology and thermal remote sensing. Innovations also include quantifying SW-GW fluxes over a range of temporal and spatial scales and developing procedures for integrating observations across scales into process-based models. The techniques developed and tested through this proposal will be of broad interest to a spectrum of researchers and professionals to inform stream restoration, contaminant remediation, nutrient dynamics and solute transport in streams. The results of this work will also have broad applicability for collaborators from industry and from non-profit organizations. This work will establish the foundation for a sustained and strengthened program to integrate the study of heat as a tracer of SW-GW interaction with educational opportunities for students enrolled in undergraduate, community college and graduate programs across a number of institutions. Mentoring relationships between undergraduate students, graduate students, faculty members, industry professionals and representatives of non-profit agencies will be formally developed to support the recruitment and success of underrepresented minority groups, including Native Americans, and women.Start Date: March 1st, 2008

职业：整合研究和教育，以促进在多个空间和时间尺度上使用热量作为地表-地下水相互作用的示踪剂。K. Lautz，纽约州立大学环境科学与林业学院河流-地下水（SW-GW）相互作用是各种水质和水量问题的关键组成部分。 已经证明难以准确地表征SW-GW相互作用，特别是在流中，并且由于空间或时间点测量的空间和时间概括的挑战，它们经常被忽略。 有一个新的兴趣在使用热作为示踪剂在水文系统中，因为热输运具有许多优势，超过传统的方法来表征SW GW的相互作用。 尽管最近的技术和分析的发展，在水文系统中的热作为示踪剂的应用，还有很多东西要学。 该提案的主要目标是整合研究和教学，以推进热传输理论的应用，以表征河流和地下水之间的水通量，并将这些通量与各种空间和时间尺度上的水质变化联系起来。 拟议的工作包括：（1）将温度的现场观测与建模联系起来，以量化不同尺度上的SW-GW通量率，以及（2）将SW-GW相互作用与地球化学变化联系起来。 该提案的研究创新包括通过使用光纤分布式温度传感器技术和热遥感来扩大观测，同时保持精细尺度的空间分辨率。 创新还包括在一系列时间和空间尺度上量化SW-GW通量，并开发将跨尺度观测整合到基于过程的模型中的程序。 通过该提案开发和测试的技术将引起研究人员和专业人员的广泛兴趣，以告知流恢复，污染物修复，营养动态和流中的溶质运移。 这项工作的结果也将广泛适用于工业界和非营利组织的合作者。 这项工作将为一个持续和加强的计划奠定基础，将热的研究作为SW-GW相互作用的示踪剂，为许多机构的本科生，社区学院和研究生课程的学生提供教育机会。 本科生、研究生、教职员工、行业专业人士和非营利机构代表之间的指导关系将正式发展，以支持招聘和代表性不足的少数群体，包括美洲原住民和妇女的成功。
