GPS Study of the Transition Between Subduction and Collision in Papua New Guinea: Equipment

9728749白银这笔拨款为购置一个大地测量全球定位卫星（GPS）接收器系统和五台用于主动构造野外研究的移动计算机提供部分费用支持。该提案是提交给地球物理（PH）计划（EAR-9725792）的配套研究提案的仪器和设施（IF）对应，该提案最近被推荐授予。研究的重点是通过GPS实地活动，确定在巴布亚新几内亚的汇聚边缘上的应变分布。PI将与UNITECH的巴布亚新几内亚合作者一道，于1998年6月和2000年6月在巴布亚新几内亚建立一个GPS网络，以测量基线。该仪器建议将提供一个单一的GPS接收器系统，该系统将被放置在巴布亚新几内亚，以便UNITECH的科学家可以在UC-Santa Cruz科学家进行的实地活动之间重新测量基线。因此，这种合作不仅为快速变形和潜在地震危险地区提供了额外的宝贵基线数据，而且还为巴布亚新几内亚的科学家及其学生提供了富有成效的技术转让。＊＊＊

9728749 Silver This grant provides partial support of the costs of acquiring a geodetic global positioning satellite (GPS) receiver system and five mobile computers for use in active tectonic field research. This proposal is the Instrumentation and Facilities (IF) counterpart of a companion research proposal submitted to the Geophysics (PH) program (EAR-9725792) which has recently been recommended for award. The research focus is to determine, via GPS field campaigns, the distribution of strain across the convergent margin in Papua New Guinea. The PI, together with Papua New Guinean collaborators from UNITECH, will establish a GPS network in Papua New Guinea in June 1998 and again in June 2000 to measure baselines. This instrumentation proposal will provide a single GPS receiver system that will be monumented and left in Papua New Guinea so that scientists from UNITECH can re- measure baselines between field campaigns conducted by UC-Santa Cruz scientists. Thus, this collaboration provides not only additional valuable baseline data in an area of rapid deformation and potential earthquake hazards, but also serves as a fruitful technology transfer to scientists within Papua New Guinea and their students. ***
