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.

该奖项是根据2021年《美国救援计划法》的全部或部分资助的（公共法117-2）。北极海洋正受到持续的气候变暖驱动的重大环境变化的影响。但是，由于我们在那里的海洋，生物学和化学状况的信息有限，因此预测未来的变化，评估可能已经发生了多少生态系统变化，或者知道这些变化是否在整个北极海洋中发生。国际科学家正在共同努力开发发品弧形调查（SAS）计划，以应对这一挑战。 SAS合作者正在对多次科学探险进行采样北极海洋的物理，生物学和化学状态。他们正在将这些新测量结果与现有数据合成，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，在北极研究方面延续了美国，并着重于阿拉斯加附近的美国北极和北部的加拿大盆地。多种教育，培训和外展活动集中于早期职业科学家，K-12学生，土著人民，本科生和研究生以及阿拉斯加当地的沿海社区。 国际努力的发现将指导对人类社区所必需的生态系统资源的预测和管理，包括当地和土著北极居民，以及大规模的商业渔业和其他经济活动。该项目将量化物理，生物学和生物地球化学在夏季范围内的量化过程中的量化量的现状，从而量化了夏季范围内的量化量的量化，以量化夏季的多个量化范围，以在夏季进行多种多样的群体之间的变化。相邻的架子，斜坡和深盆地，并提供当代基线，可以将未来的变化进行比较以检测对气候驱动因素的反应。 SAS已经组织了三个主要的研究领域：（1）对生态系统和碳周期的重要性驱动因素，（2）生态系统反应，以及（3）碳循环本身，与总体问题联系在一起：北极洋系统的当前状态是什么，什么是什么？该提案在这个总体的保护伞下提出了特定的，集中的研究问题，这将直接推进我们对这个知之甚少的地区的基本理解，同时还提供了观察性和实验数据，这将有助于更广泛的SAS目标。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，并鼓励并招募其他美国补充建议加入该项目。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来进行评估的。
