The Arctic is warming at more than twice the rate as the rest of the planet with subsequent changes to the microbial population. The coastal community of Kotzebue is located 30 miles north of the Arctic Circle on the eastern shore of Kotzebue Sound, an embayment of the southeast Chukchi Sea, in northwest Alaska. Kotzebue Sound is commercially important to the community, which harvests on average 230,000 chum salmon, and the fish and marine mammals from the Sound provide up to 70% by weight of their annual food harvest. But, as important as the Sound is to the local community, there have been few comprehensive studies of phytoplankton - the microbes that make up the base of the food web in the Sound. Thus, knowledge of phytoplankton populations including that of Harmful Algal Blooms that could impact food security is also of immediate importance to the people who live here. This proposal initiates a year-round long-term observational program of phytoplankton populations, relevant physical characteristics, and nutrient concentrations in the waters around Kotzebue. This project will measure water column hydrography, nutrient concentrations, and phytoplankton populations at six sites using boats during the ice-free season and at two locations through the ice in the winter. In addition, a YSI Exo 2 sonde will be deployed to make measurements every 10 minutes during the ice-free season. Information about interannual and annual changes in an estuarine system produced here is not currently available through large scale programs like the Distributed Biological Observatory or the offshore research projects occurring in the adjacent Chukchi Sea and thus this project fills an important scientific and societally relevant gap. This project to set up a sustained observation program has been co-conceived and co-designed with coPI Whiting, the Environmental Program Director for the Native Village of Kotzebue. Given the importance of knowledge about changes in phytoplankton populations and cyanotoxins to food security, findings from this project will be presented to the community in a variety of ways including: reports to the Tribal Council, radio interviews, newsletters delivered to residents, evening presentations at the community center, presentations at the middle and high school, as well as social media such as Facebook and Instagram pages. Findings will also be presented to Alaska Harmful Algae Bloom Network run through the Alaska Ocean Observing System. Kotzebue middle and high school students will be provided a Planktoscope and the teachers will be trained to set up class projects for sampling waters around Kotzebue for the students to learn about local plankton.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.

由于地球的其余部分随后变化对微生物种群，北极的变暖是速率的两倍以上。 Kotzebue的沿海社区位于北极圈以北30英里处，位于Kotzebue Sound的东海岸，这是阿拉斯加西北部东南Chukchi Sea的嵌入。 Kotzebue Sound对社区来说在商业上很重要，该社区平均收获230,000个Chum鲑鱼，而来自声音的鱼类和海洋哺乳动物的年度食品收获的重量最高为70％。但是，就像声音对当地社区一样重要，几乎没有关于浮游植物的全面研究 - 构成声音中食物网的基础的微生物。因此，对可能影响粮食安全的有害藻类包括的浮游植物种群的知识对于居住在这里的人们而言也很重要。该提案启动了浮游植物种群，相关的身体特征和养分浓度的全年长期观察计划。 该项目将在无冰季节使用船只在六个地点和冬季的两个地点测量六个地点的水柱水文学，营养浓度和浮游植物种群。此外，将在无冰季节内每10分钟进行一次YSI EXO 2 SONDE进行测量。目前，有关此处生产的河口系统中年度和年度变化的信息目前尚未通过大规模计划（例如分布式生物天文台或邻近Chukchi Sea中发生的海上研究项目）获得，因此该项目填补了一个重要的科学和社会相关的差距。这个建立持续观察计划的项目已与本地村庄Kotzebue的环境计划总监Copi Whiting共同设计并共同设计。考虑到有关浮游植物种群变化和氰毒素变化对粮食安全的知识的重要性，该项目的发现将以各种方式向社区介绍，包括：向部落委员会的报告，广播访谈，新闻通讯，向居民发送给居民的通讯，在中间和高中的社区中心，以及社交媒体的介绍，以及Facebook Agragram和Instergagram页面和Insteragram页面。调查结果还将提交通过阿拉斯加海洋观察系统运行的阿拉斯加有害藻类网络。将为Kotzebue中学和高中生提供浮游生物镜，并将对老师进行培训，以建立课堂项目，以便在Kotzebue周围进行抽样，以便学生了解当地的Plankton。这一奖项反映了NSF的法定任务，并认为通过基金会的知识分子优点和广泛的影响来评估NSF的法定任务。
