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.
该奖项全部或部分由2021年美国救援计划法案(公法117-2)资助。北冰洋正在受到重大环境变化的影响,例如持续气候变暖导致的海冰损失。然而,由于我们对那里的海洋,生物和化学条件的信息有限,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,这是具有挑战性的。国际科学家正在共同努力开发天气北极调查(SAS)计划,以应对这一挑战。 SAS的合作者正在对北冰洋的物理,生物和化学状况进行多次科学考察。他们将这些新的测量结果与现有数据相结合,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,继续美国在北极研究中的突出地位,重点关注阿拉斯加附近的美国北极地区和北部的加拿大盆地。多种教育,培训和推广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,以及当地阿拉斯加沿海社区。 国际努力的结果将指导对人类社区至关重要的生态系统资源的预测和管理,包括当地和土著北极居民,以及大规模商业渔业和其他经济活动。该项目将量化北极地区的物理,生物,在夏末的多学科巡航期间,通过与历史数据的比较,数据,以量化相邻大陆架、斜坡和深盆地之间的联系,并提供一个当代基线,可与未来的变化进行比较,以检测对气候驱动因素的反应。该SAS组织围绕三个主要的研究领域:(1)重要的生态系统和碳循环的物理驱动因素,(2)生态系统的反应,(3)碳循环本身,与首要问题:什么是目前的状态,什么是北极海洋系统正在进行的主要转变?这项建议提出了具体的,重点研究问题,在这个总体保护伞下,将直接推进我们对这个知之甚少的地区的基本了解,同时也提供了观测和实验数据,将有助于更广泛的SAS目标。一个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建议加入该项目。该奖项反映了NSF的法定使命,并已被认为是值得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的支持。
