9321556 Van der Veen This award is for support for a study on the mechanics of Columbia Glacier, Alaska, USA during its current rapid retreat. The extensive data set of surface elevations and velocities obtained from many repeat aerial photogrammetries of the glacier will be analyzed in order to identify the sites of, and magnitudes of mechanical controls on the lower part of the glacier. This data will also provide information to help determine whether the ongoing retreat is associated with a major change in flow style, and to test various calving relations at each phase of retreat of the ice front. The understanding of the controls of the collapse of the Columbia Glacier, obtained from these data, will be very helpful in understanding major collapses of other glaciers. ***

9321556货车德维恩这个奖项是为了支持对哥伦比亚冰川，阿拉斯加，美国在其目前的快速撤退力学研究。 将分析从冰川的许多重复航空摄影测量中获得的大量表面高程和速度数据集，以确定冰川下部机械控制的位置和大小。 这些数据还将提供信息，以帮助确定正在进行的撤退是否与流动风格的重大变化，并测试各种产犊关系在每个阶段的退缩的冰锋。 从这些数据中了解哥伦比亚冰川崩塌的控制因素，将对了解其他冰川的重大崩塌非常有帮助。 ***
