项目摘要
The GreenFjord-FIBER project is a scientific study that uses high-tech measurements to understand how Greenlandic glaciers flowing into the ocean change between winter and summer. The investigators are focusing on the points where the ice meets the ocean. With special sensors measuring vibrations and temperature, the investigators aim to measure where and when icebergs detach from the glacier and fall into the ocean. The investigators also want to find out where warm ocean water is melting the ice and if there is a connection to the speed at which the glacier flows into the ocean. The measurements will help us learn more about how Greenland's glaciers will change in the future and what that might mean for sea levels around the world. In collaboration with a local Greenlandic teacher-trainee, the scientific results of the study and their implications for local communities will be disseminated in Greenland’s classrooms.The proposal aims to test the hypothesis that a regime change in melt source regions occurs during the spring-to-summer transition period, shifting from temperature-dominated melt and calving to sub-glacial discharge-dominated processes. To test this hypothesis, the investigators will deploy a new optical fiber instrument at the calving front of the Qajuuttap Sermia tidewater glacier in Greenland. This instrument will measure acoustic and temperature data to better understand the effect of sub-glacial melt and discharge on calving. The project will generate novel measurements from Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) systems, making a compelling proof-of-concept for glacier-ocean interface observations, an environment that is notoriously treacherous for equipment and personnel. The inclusion of broadband instruments on land, seismometers on the ocean bottom, and conductivity, temperature, and depth (CTD) casts from boats will provide important benchmarks against the measurements from DTS/DAS. The project will support two early-career researchers, one postdoc, and an undergraduate in a University of Washington hosted summer research program. In collaboration with a local Greenlandic teacher-trainee, the scientific results of the study and their implications for local communities will be disseminated in Greenland’s classrooms.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
GreenFjord-FIBER项目是一项科学研究,它使用高科技测量来了解流入海洋的格陵兰冰川在冬季和夏季之间的变化。调查人员将重点放在冰层与海洋交汇的地方。通过测量振动和温度的特殊传感器,调查人员的目标是测量冰山何时何地从冰川分离并落入海洋。调查人员还想找出温暖的海水在哪里融化了冰,以及冰川流入海洋的速度是否与此有关。这些测量将帮助我们更多地了解格陵兰冰川未来将如何变化,以及这对世界各地海平面的影响。在与一名当地的格陵兰实习教师合作下,这项研究的科学结果及其对当地社区的影响将在格陵兰的教室中传播。该提案旨在验证这样一种假设,即在春夏过渡期间,融冰源区域的状态发生了变化,从温度主导的融冰和产犊过程转变为冰下流量主导的过程。为了验证这一假设,研究人员将在格陵兰卡尤塔普塞尔米亚潮汐冰川的产冰前沿部署一种新的光纤仪器。该仪器将测量声波和温度数据,以更好地了解冰下融化和流量对冰裂的影响。该项目将从分布式温度传感(DTS)和分布式声学传感(DAS)系统中产生新的测量结果,为冰川-海洋界面观测提供引人注目的概念验证,这是一个众所周知的对设备和人员危险的环境。陆地上的宽带仪器、海底的地震仪以及船上的电导率、温度和深度(CTD)模型将为DTS/DAS的测量提供重要的基准。该项目将支持两名早期职业研究人员,一名博士后和一名华盛顿大学主持的暑期研究项目的本科生。在与一名当地的格陵兰实习教师合作下,这项研究的科学结果及其对当地社区的影响将在格陵兰的教室中传播。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
