项目摘要

This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).The Arctic Ocean is being affected by major environmental changes, such as sea ice loss, driven by ongoing climate warming. However, since we have limited information on oceanic, biological, and chemical conditions there, it is challenging to predict future changes, to evaluate how much ecosystem change may already have occurred, or to know if these changes are occurring over the entire Arctic Ocean. International scientists are working together to develop the Synoptic Arctic Survey (SAS) program to address this challenge. SAS collaborators are sampling the physical, biological, and chemical status of the Arctic Ocean on multiple scientific expeditions. They are synthesizing these new measurements with existing data, and projecting future changes via modeling. This project is the core of a US contribution to the international SAS program, continuing US prominence in Arctic research, and focuses on the US Arctic near Alaska and in the Canadian Basin to the north. Multiple educational, training, and outreach activities are focusing on early career scientists, K-12 students, Indigenous peoples, undergraduate and graduate students, and local Alaskan coastal communities. Findings from the international effort will guide predictions and management of ecosystem resources that are essential to human communities, including local and Indigenous Arctic residents, and large-scale commercial fisheries and other economic activities.This project will quantify the current state of the physical, biological, and biogeochemical marine systems of the Canadian Basin during a multidisciplinary cruise in late summer to detect changes through comparisons with historical data, to quantify linkages between the adjacent shelves, slopes, and deep basins, and to provide a contemporary baseline against which future changes can be compared to detect responses to climate drivers. The SAS has organized around three major research areas: (1) physical drivers of importance to the ecosystem and carbon cycle, (2) the ecosystem response, and (3) the carbon cycle itself, linked with the overarching question: What is the present state and what are the major ongoing transformations of the Arctic marine system? This proposal poses specific, focused research questions under this overarching umbrella that will directly advance our basic understanding of this poorly understood region, while also providing observational and experimental data that will contribute to the broader SAS objectives. A Project Coordination Office will facilitate coordination of US project components with international research activities and will encourage and recruit additional US complementary proposals to join the project.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.
该奖项的全部或部分资金来自《2021年美国救援计划法案》(公法117-2)。北冰洋正受到持续气候变暖导致的重大环境变化的影响,例如海冰消失。然而,由于我们对那里的海洋、生物和化学条件的信息有限,因此很难预测未来的变化,评估生态系统可能已经发生了多少变化,或者知道这些变化是否正在整个北冰洋发生。国际科学家正在共同努力开发北极天气调查(SAS)计划,以应对这一挑战。SAS的合作者们正在对北冰洋的物理、生物和化学状况进行多次科学考察。他们正在将这些新的测量数据与现有数据相结合,并通过建模预测未来的变化。该项目是美国对国际SAS计划的贡献的核心,继续保持美国在北极研究中的突出地位,重点放在阿拉斯加附近的美国北极和北部的加拿大盆地。多项教育、培训和外联活动的重点是早期职业科学家、K-12学生、土著人民、本科生和研究生以及阿拉斯加沿海当地社区。这一国际努力的结果将指导对人类社区(包括北极当地和土著居民)以及大规模商业渔业和其他经济活动至关重要的生态系统资源的预测和管理。该项目将量化加拿大盆地在夏末一次多学科巡航期间的物理、生物和生物地球化学海洋系统的现状,通过与历史数据的比较来发现变化,量化相邻大陆架、斜坡和深盆地之间的联系,并提供一个当代基线,可以将未来的变化与之进行比较,以检测对气候驱动因素的反应。SAS围绕三个主要研究领域进行了组织:(1)对生态系统和碳循环具有重要意义的物理驱动因素,(2)生态系统响应,以及(3)碳循环本身,与首要问题相关:北极海洋系统的现状是什么,正在发生的主要变化是什么?这一建议在这一总体框架下提出了具体的、有重点的研究问题,将直接促进我们对这一知之甚少的地区的基本理解,同时也提供了有助于更广泛的SAS目标的观测和实验数据。项目协调办公室将促进美国项目组成部分与国际研究活动的协调,并将鼓励和招募更多的美国补充性建议加入该项目。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
