Travel Support for US Participation in the Interim Assemblies of IUGG

年轻的美国科学家和学生将参加国际地磁与航空协会（IAGA）的科学大会；国际大地测量学会（IAG）；以及国际水文科学协会（IAHS）。这些大会将为全球各大会所涵盖学科的科学家提供机会，就最近的科学成就或最近的研究交流信息；确定未来研究的需要和优先次序；并建立工作关系的基础，以计划和开展研究，以满足这些需求。IAGA涵盖古磁学、岩石磁学、行星磁学和电磁感应等科学领域；中大气、电离层、中间层和极地大气的航空学；磁性层的流程;太阳风;地磁观测，包括模型、数据和指数的开发。国际地质小组促进发展一系列地球科学应用的参考框架；大地测量学与地球动力学；监测地球的重力场和自转，地球表面（包括海洋和冰）的变形，与全球大地测量观测系统（GGOS）的相互作用，特别是在陆地、海洋和大气过程和特征的定位和遥感方面。IAHS涵盖地表水和地下水等领域；水质量;水资源;冰雪水文；大气、土壤和植被之间的相互作用；以及大陆侵蚀。本次大会感兴趣的具体议题是地表水和地下水依赖生态系统的生态水文学；承压含水层地下水的可持续性；综合利用地表水和地下水资源。

Young U.S. scientists and students will participate in the Scientific Assemblies of the International Association of Geomagnetism and Aeronomy (IAGA); the International Association of Geodesy (IAG); and the International Association of Hydrological Sciences (IAHS). These Assemblies will provide an opportunity for scientists across the globe in the disciplines covered by each Assembly to exchange information on the most recent scientific accomplishments of recent research; to identify needs and priorities for future research; and to develop a basis for working relationships to plan and conduct research to meet these needs.The IAGA covers scientific areas such as paleomagnetism, rock magnetism, planetary magnetism, and electromagnetic induction; aeronomy of the middle atmosphere, ionosphere, mesosphere, and Polar atmosphere; magnetospheric processes; solar winds; and geomagnetic observatories, including development of models, data and indices. The IAG promotes development of a reference frame for a range of geosciences applications; geodesy and geodynamics; monitoring the gravity field and rotation of the Earth, the deformation of the Earth surface including ocean and ice, interaction with the Global Geodetic Observing System (GGOS), especially with respect to positioning and remote sensing of land, oceanic and atmospheric processes and features. The IAHS covers such areas as surface and ground water; water quality; water resources; snow and ice hydrology; interactions between the atmosphere, soil and vegetation; and continental erosion. Specific topics of interest at this Assembly are the ecohydrology of surface and groundwater dependent ecosystems; sustainability of groundwater in stressed aquifers; and integrated approaches to surface and groundwater resources.
