AbstractProposal: Collaborative Research: Marine microgels: A microlayer source of summer CCN in high Arctic open leadsP.I.:Erin C PettitUniversity of Alaska FairbanksShad R O?NeelUniversity of Colorado at BoulderJeffrey A NystuenUniversity of WashingtonProposal # 0806317 Investigators from the University of Alaska Fairbanks, the University of Colorado at Boulder, and the University of Washington have received funding to test a novel method for measuring the magnitude and variability of subglacially discharged water. 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.

摘要提案：合作研究：海洋微凝胶：北极高空开放引线中夏季 CCN 的微层来源PI：Erin C Pettit 阿拉斯加大学费尔班克斯分校Shad R O Neel 科罗拉多大学博尔德分校杰弗里 A Nystuen 华盛顿大学提案＃0806317 来自阿拉斯加大学费尔班克斯分校的研究人员，科罗拉多大学博尔德分校和华盛顿大学已获得测试资金一种测量冰下排放水量和变化的新方法。了解此类排放是我们对冰盖和冰川质量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。这些研究人员将利用来自湍流上升流、气泡形成和沉积物碰撞的声学信号来量化冰下淡水排放的幅度和变化。该研究将由蒙大拿州立大学科学与自然历史电影制作项目的电影制作人记录。
