9302122 WARE, Randolph H. 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 is 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).

9302122 WARE，兰多夫H. 该计划将利用全球定位系统监测印度-澳大利亚板块和太平洋板块之间的板块边界复合体的地壳运动。 这一复合体包括赫布里底群岛弧、斐济高原、劳盆地和汤加弧，其特点是板块聚合和弧后扩张速度非常快。 通过使用全球定位系统建立跨越该区域许多主要构造单元的岛间基线，通过对这些基线的反复观测，将有可能直接观察板块会聚、弧内应变和弧后扩张的运动学。 将进行这项实验的联合体包括北卡罗来纳州州立大学、康奈尔大学、得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）。
