项目摘要

Climate warming is melting the Greenland Ice Sheet and contributing to global sea level rise. In order to understand how the Greenland Ice Sheet will behave in the future, we will look to the geologic past. Material recovered from the bottom of ice cores, such as sediment and bedrock, can contain evidence about the ecosystems and landscapes from past ice-free times in Greenland. Drilled through nearly 1400 m of ice during the 1960s, the Camp Century ice core recovered ~3.5 m of frozen sediment at its base that was lost for several decades in a freezer. In this project, we will conduct a comprehensive study of the sediment at the bottom of this ice core. We will use laboratory analyses to determine when and how many times the Greenland Ice Sheet melted in the past, to study the types of ecosystems that thrived during those times, and to understand how the ice sheet erodes the landscape. This new information will allow us to better understand how Greenland Ice Sheet responds to warming and its potential contribution to sea-level rise, as well as understand what types of ecosystems develop in Greenland when ice melts away. Our team includes a filmmaker who will engage with media outlets to tell a story about how ground-breaking research, both in the 1960s and today, has advanced our understanding of Earth’s climate and its polar regions. Along with videos, websites, and social media, we will develop K-12 curricula that tell the story of Camp Century and teach the process of scientific research. In order to understand how the Greenland Ice Sheet may respond to future climate warming, we look to the geologic past. Material recovered from the bottom of ice cores, such as sediment and bedrock, contains information from past times when the ice sheet was smaller and sea level was higher. In northwestern Greenland, the Camp Century ice core was drilled through 1400 m of ice and recovered ~3.5 m of frozen sediment at its base; however, this sediment was not fully studied and then misplaced for decades in a freezer. In this international collaborative project, we will conduct a comprehensive study of the sediment at the bottom of the Camp Century ice core by applying a range of biologic, isotopic, and geochemical analyses along a depth profile in the sediment. We will use a wide range of analyses to determine the timing and number of ice-free events in northwest Greenland, to fully characterize the ecosystems that emerged during those times, and to understand the erosional processes operating at the base of ice sheets. The new information will allow us to better understand the sensitivity of the Greenland Ice Sheet to climate warming, as well as what types of ecosystems may develop in Greenland as ice melts away. Our work will be a blueprint for future analyses of sediments recovered from beneath ice sheets. The climate information extracted from this ice core tells the exciting history of climate change and climate science over 50+ years. Our team includes a filmmaker who will engage with media outlets to tell a story about how ground-breaking research, both in the 1960s and today, has advanced our understanding of Earth’s climate and its polar regions, and to show the utility of science to society. Along with videos, websites, and social media, we will develop K-12 curricula that tell the story of Camp Century and teach the process of interdisciplinary science.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.
气候变暖正在融化格陵兰冰盖,导致全球海平面上升。为了了解格陵兰冰盖在未来的表现,我们将回顾过去的地质学。从冰芯底部回收的物质,如沉积物和基岩,可以包含格陵兰过去无冰时期生态系统和景观的证据。在20世纪60年代钻穿了近1400米的冰层,世纪营地冰芯在其底部恢复了约3.5米的冻结沉积物,这些沉积物在冰箱中丢失了几十年。在这个项目中,我们将对冰芯底部的沉积物进行全面研究。我们将使用实验室分析来确定格陵兰冰盖在过去何时融化以及融化了多少次,研究在这些时期蓬勃发展的生态系统类型,并了解冰盖如何侵蚀景观。这些新信息将使我们更好地了解格陵兰冰盖如何应对变暖及其对海平面上升的潜在贡献,以及了解当冰融化时格陵兰岛会发展出什么类型的生态系统。我们的团队包括一位电影制片人,他将与媒体合作,讲述一个关于20世纪60年代和今天的突破性研究如何增进我们对地球气候及其极地地区的了解的故事。沿着视频、网站和社交媒体,我们将开发K-12课程,讲述世纪营地的故事,并教授科学研究的过程。为了了解格陵兰冰盖如何应对未来的气候变暖,我们回顾了过去的地质学。从冰芯底部回收的物质,例如沉积物和基岩,包含过去冰盖较小、海平面较高时的信息。在格陵兰岛西北部,世纪营地冰芯钻穿了1400米的冰层,并在其底部回收了约3.5米的冻结沉积物;然而,这些沉积物没有得到充分研究,然后在冰箱里放了几十年。在这一国际合作项目中,我们将对世纪营冰芯底部的沉积物进行全面研究,方法是沿着沉积物的深度剖面进行一系列生物、同位素和地球化学分析。我们将使用广泛的分析来确定格陵兰西北部无冰事件的时间和数量,以充分描述在这些时间出现的生态系统,并了解冰盖底部的侵蚀过程。新的信息将使我们能够更好地了解格陵兰冰盖对气候变暖的敏感性,以及随着冰的融化,格陵兰岛可能会发展出什么类型的生态系统。我们的工作将成为未来分析冰盖下沉积物的蓝图。从冰芯中提取的气候信息讲述了50多年来气候变化和气候科学的令人兴奋的历史。我们的团队包括一位电影制片人,他将与媒体合作,讲述一个关于20世纪60年代和今天的突破性研究如何促进我们对地球气候及其极地地区的理解的故事,并展示科学对社会的效用。沿着视频、网站和社交媒体,我们将开发K-12课程,讲述世纪营的故事,教授跨学科科学的过程。该奖项反映了NSF的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
