9319698 Humphrey This award is for support of a Small Grant for Exploratory Research (SGER) to document and analyze a surge, which is in progress, on the Bering Glacier in Alaska. Surging is defined as periodic, very rapid movements of large quantities of ice within a glacier, alternating with much longer periods of near stagnation. The Bering Glacier is the longest (191 kilometers) and largest (5,173.5 square kilometers) glacier in North America. This study will monitor the basal hydrology of the surge, by monitoring outlet streams that emerge from the glacier at different elevations. Automated observations of water, suspended, and dissolved loads from glacial outlets will monitor the subglacial hydraulics which, according to present understanding, control the propagation of surges. ***

9319698 Humphrey该奖项是为了支持探索性研究（SGER）的小额赠款，以记录和分析阿拉斯加白令冰川正在进行的激增。 涌动被定义为冰川内大量冰的周期性、非常快速的运动，与更长时间的接近停滞交替。 白令冰川是北美最长（191公里）和最大（5，173.5平方公里）的冰川。 这项研究将通过监测从不同海拔的冰川流出的水流来监测涌浪的基础水文。 自动化观测水，悬浮和溶解负荷从冰川出口将监测冰下水力学，根据目前的理解，控制浪涌的传播。 ***
