项目摘要

The Arctic is warming faster than any other place on Earth, with sea ice declining rapidly and sources of sea spray and aerosol emissions derived from living organisms (biogenic) are consequently changing. Utqiagvik is at the forefront of this change, abutting one of the largest areas of sea ice loss. These atmospheric aerosols could have far-reaching impacts to both the climate, environment and resident community. Because this change has happened largely in the last decade, now is an important time to document changes and continue a data record that will allow for a characterization of the New Arctic. The longest and most complete record of airborne fine particles (or “aerosol”) and their properties in the American Arctic is that of Utqiagvik, where NSF, the National Oceanic and Atmospheric Administration and the Department of Energy have contributed to making this unique location serve as a regional record of changes in atmospheric aerosol properties. That record has served as the basis for hundreds of publications on questions from atmospheric chemistry to climate science to ecology and biodiversity conservation, which clearly demonstrate the broad, cross-disciplinary scientific value of these measurements.This research will extend the baseline measurements of this Arctic aerosol record, including a continuation of the 15-year record of submicron inorganic components, re-instituting the 2-year record of organic components collected a decade ago, enhancing the chemical analysis with sulfur isotopes to improve interpretation of emission sources, continuing particle number size distribution measurements, and re-starting cloud condensation nuclei measurements. Re-starting sampling for organic components provides a comparison to that of 2008-2010, documenting the myriad of source changes in the last decade. Observations for continuing size distribution records and re-starting cloud condensation nuclei measurements provides the link from the chemical record of sources to the physical impacts on climate and the environment. This project will also allow analysis and archiving of the last 7 years of inorganic filters that were collected and the next 5 years, extending the inorganic aerosol composition record to almost 30 years. In addition to making the data widely available for a breadth of research, a journalist will publish articles in local news media to broaden the awareness of Utqiagvik’s historic role as an Arctic observatory.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.
北极变暖的速度比地球上任何其他地方都快,海冰迅速减少,海洋喷雾和生物体(生物源)产生的气溶胶排放源也因此发生变化。乌特恰格维克处于这一变化的前沿,毗邻海冰损失最大的地区之一。这些大气气溶胶可能对气候、环境和居民社区产生深远的影响。由于这种变化主要发生在过去十年中,现在是记录变化并继续记录数据的重要时刻,这将有助于描述新北极的特征。关于美国北极地区空气中细颗粒物(或“气溶胶”)及其特性的最长和最完整的记录是乌特恰格维克,美国国家科学基金会、国家海洋和大气管理局以及能源部为使这一独特的地点成为大气气溶胶特性变化的区域记录做出了贡献。这一记录已成为数百份出版物的基础,涉及从大气化学到气候科学,再到生态学和生物多样性保护等问题,清楚地表明了这些测量的广泛、跨学科的科学价值。这项研究将扩展这一北极气溶胶记录的基线测量,包括延续15年来对亚微米无机成分的记录,重新建立十年前收集的有机成分的两年记录,加强硫同位素的化学分析,以改善对排放源的解释,继续进行颗粒数量大小分布测量,并重新开始云凝结核测量。重新开始对有机成分进行采样,与2008-2010年的采样进行了比较,记录了过去十年中源的无数变化。观测持续的大小分布记录和重新开始云凝结核测量提供了从源的化学记录到对气候和环境的物理影响的联系。该项目还将允许对过去7年和未来5年收集的无机过滤器进行分析和存档,将无机气溶胶成分记录延长至近30年。除了广泛提供数据用于广泛的研究之外,一名记者还将在当地新闻媒体上发表文章,以扩大人们对乌特恰格维克作为北极观测站的历史作用的认识。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。
