Collaborative Research: A New Method of Observing Variability in Freshwater Discharge from Arctic and Antarctic Marine-Terminating Glaciers using Passive Acoustic Measurements

艾琳C佩蒂阿拉斯加费尔班克斯大学R O？来自阿拉斯加费尔班克斯大学、博尔德科罗拉多大学和华盛顿大学的研究人员已经获得了一笔资金，用于测试一种测量冰川下排放水的大小和变化的新方法。了解这种排放是我们对冰盖和冰川物质平衡知识的最大差距之一，但我们目前缺乏测量排放的方法。这些研究人员将使用来自湍流上升流、气泡形成和沉积物碰撞的声学信号来量化冰下淡水流量的大小和可变性。这项研究将由蒙大拿州立大学的一位电影制作人记录下来。科学与自然历史电影制作课程。

Understanding such discharges is one of the greatest gaps in our knowledge of ice sheet and glacier mass balance, but we currently lack a method of measuring the discharges. These investigators will use acoustic signals from turbulent upwelling, bubble formation, and sediment collisions to quantify the magnitude and variability of subglacial freshwater discharge. The research will be documented by a filmmaker from Montana State University?s Science and Natural History Filmmaking program.
