项目摘要
The overflow of dense water across the Greenland-Scotland Ridge (GSR), and its subsequent entrainment, is a fundamental component of the Atlantic Meridional Overturning Circulation (AMOC) which helps maintain Earth’s climate. It is critically important to determine the mechanisms, forcing, and variability of the AMOC. The proposed collaborative program, including a mooring array, hydrographic surveys and modeling, will provide a major contribution towards this goal. This project will determine where the densest water is formed in the Nordic Seas, how this water progresses to the GSR, and how it is modified along the way, including the role of atmospheric forcing. This in turn will provide a better understanding of the means by which the warming climate may impact the AMOC. The project is part of a separately funded large international program. It will fund a post-doctoral investigator and two part-time guest graduate students. An outreach program will be undertaken that includes a project website and a host of activities engaging the public in the fieldwork. A professional photographer/filmmaker/illustrator/writer will participate on one of the shipboard surveys. This project would maintain a one year high-resolution mooring array to measure the Iceland-Faroe Slope Jet, which appears to be the main source of dense water feeding the Faroe Bank Channel overflow, and which in turn accounts for roughly half of the total overflow transport across the Greenland Scotland Ridge. Accompanying shipboard hydrographic/velocity surveys will trace the flow upstream to its source region(s), and also document its downstream evolution to where it overflows in the Faroe Bank Channel. The use of a Global Climate Model, idealized model, and simple theory will put the observations into a dynamical context.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.
稠密水越过格陵兰-苏格兰海脊(GSR)的溢出及其随后的夹带,是大西洋经向翻转环流(AMOC)的基本组成部分,有助于维持地球的气候。确定AMOC的机制、强迫和变化是至关重要的。拟议的合作计划,包括一个系泊阵列,水文调查和建模,将为实现这一目标作出重大贡献。该项目将确定北欧海中密度水的形成位置,这些水如何进入海硅渣,以及它如何在沿着发生变化,包括大气强迫的作用。这反过来又将使人们更好地了解气候变暖可能影响AMOC的方式。该项目是一个单独资助的大型国际项目的一部分。它将资助一名博士后研究员和两名兼职客座研究生。将开展一项外联方案,其中包括一个项目网站和一系列让公众参与实地工作的活动。一名专业摄影师/电影制片人/插画家/作家将参加其中一次船上调查。该项目将维持一年的高分辨率系泊阵列,以测量冰岛-法罗群岛斜坡急流,这似乎是法罗群岛银行渠道溢流的主要密集水来源,而这又占格陵兰苏格兰海脊总溢流量的大约一半。伴随的船上水文/流速调查将追踪上游的水流至其来源区域,并记录其下游演变至法罗银行海峡的溢流处。该奖项反映了NSF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。
