COLLABORATIVE RESEARCH: Monitoring Crustal Motion in the Southwest Pacific Using the Global Positioning System (GPS)

PI将使用全球定位系统（GPS）， 监测板块边界复合体的地壳运动， 印度-澳大利亚板块和太平洋板块 这个复杂的， 包括赫布里底群岛弧、斐济高原、劳盆地和 汤加岛弧的特点是极高的板块形成率 会聚和弧后扩张。 通过使用GPS来建立 跨越许多主要构造带的岛屿间基线 在该地区的元素，这将是可能的，通过重复 观察这些基线，直接观察 板块会聚、弧内应变和弧后运动学 蔓延 进行实验的财团 包括北卡罗来纳州州立大学、康奈尔大学、 德克萨斯大学奥斯汀分校、科罗拉多大学、 国家大地测量局、ORSTOM（新喀里多尼亚）和 新南威尔士大学（澳大利亚）

The PIs will use the Global Positioning System (GPS) to monitor crustal motion across a plate boundary complex between the Indo-Australian and Pacific plates. This complex, which includes the Hebrides arc, the Fiji Plateau, the Lau Basin and the Tonga arc, is characterized by very high rates of plate convergence and back-arc spreading. By using GPS to establish inter-island baselines that straddle many of the major tectonic elements in the region, it will be possible, by repeated observation of these baselines, to directly observe the kinematics of plate convergence, intra-arc strain and back-arc spreading. The consortium that will perform the experiment included North Carolina State University, Cornell University, the University of Texas at Austin, the University of Colorado, the National Geodetic Survey, ORSTOM (New Caledonia) and the University of New South Wales (Australia).
