项目摘要

Understanding the intricate relationship between physical oceanography and marine ecosystems is crucial for predicting the impacts of climate variability and shifts on productive Arctic ecosystems. This research focuses on Greenland fjords and adjacent shelf seas, which are areas of immense ecological and socio-economic importance, particularly to Arctic Indigenous communities. These ecosystems, vital for local fisheries, are influenced by physical transport processes such as water circulation and mixing. In collaboration with scientists at the Greenland Institute of Natural Resources (GINR), the researchers will investigate the connections between physical oceanography and marine ecology in the fjord system around Greenland’s capital, Nuuk. By combining field observations with an advanced computer model of the fjord system, the researchers will examine how physical transport processes affect nutrient supply, primary productivity, and ultimately, the food supply for fish and marine mammals. This endeavor not only advances scientific understanding, but also addresses broader societal concerns by creating knowledge to inform sustainable management practices, thereby enhancing the resilience of local communities to climate-induced changes in marine resources. The project is led by early career scientists, including two who are women. The project will also train two postdoctoral fellows and will provide opportunities for the public in the U.S. and Greenland to engage with the project.The project involves targeted field campaigns in the fjord system around Nuuk, Greenland to collect hydrographic, turbulence, nutrient and benthic fauna samples near potential mixing hotspots such as sills, narrow straits or the steep fjord walls, and in winter conditions in close proximity to a glacier front. A coupled ocean, sea ice, and marine biogeochemistry model, constrained with observational data, will be used to elucidate the mechanisms through which physical transport influences ecological dynamics in the fjords. Specific objectives include assessing the role of lateral transport in spatial nutrient distribution, and evaluating the impact of vertical mixing on primary productivity. Based on the modeling framework and maps of distribution of benthic habitats derived from video surveys, as well as process-based links inferred from the collected observations, the researchers will link benthic habitat distribution with the variability of physical and biogeochemical fjord conditions. Simulations of future conditions will offer a framework for predicting ecosystem responses to environmental changes, a product that will aid in the assessment of the future of vital marine resources upon which local Indigenous communities depend. The project will host outreach events in Nuuk and Kapisillit, and a scientific workshop at the Greenland Institute of Natural Resources to discuss the utility of the data-constrained coupled physical-biogeochemistry model. These events will facilitate U.S.-Greenland research collaborations. Within the U.S., the project supports the career development of early-career scientists and will further develop a diverse STEM workforce through outreach events that encourage young women to pursue Arctic marine science.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.
了解物理海洋学和海洋生态系统之间的复杂关系对于预测气候变化和变化对生产性北极生态系统的影响至关重要。这项研究重点关注格陵兰峡湾和邻近的陆架海,这些地区具有极其重要的生态和社会经济意义。这些生态系统对当地渔业至关重要,受到水循环和混合等物理运输过程的影响,研究人员将与格陵兰自然资源研究所(GINR)的科学家合作,研究物理海洋学之间的联系。和海洋通过将实地观察与峡湾系统的先进计算机模型相结合,研究人员将研究格陵兰岛首府努克周围峡湾系统的生态,研究物理运输过程如何影响营养供应、初级生产力以及最终影响鱼类和海洋生物的食物供应。这项努力不仅增进了科学认识,还通过创造知识为可持续管理实践提供信息,解决了更广泛的社会问题,从而增强了当地社区对气候引起的海洋资源变化的适应能力。其中包括两名女性。该项目还将培训两名博士后研究员,并将为美国和格陵兰岛的公众提供参与该项目的机会。该项目涉及在格陵兰岛努克周围的峡湾系统进行有针对性的实地活动,以收集水文、湍流、营养物和底栖动物样本靠近潜在的混合热点,如岩台、狭窄的海峡或陡峭的峡湾壁,以及在冬季条件下靠近冰川前缘的海洋、海冰和海洋。受观测数据约束的生物地球化学模型将用于阐明物理运输影响峡湾生态的动态,具体目标包括评估横向运输在空间养分分布中的作用,以及评估垂直混合对初级生产力的影响。根据视频调查得出的海底栖息地分布的建模框架和地图,以及从收集的观测结果推断出的基于过程的联系,研究人员将把海底栖息地的分布与物理和生物多样性的变化联系起来。对未来条件的模拟将为预测生态系统对环境变化的反应提供一个框架,该产品将有助于评估当地土著社区所依赖的重要海洋资源的未来。该项目将在努克举办外展活动。和卡皮西利特,以及格陵兰自然资源研究所的科学研讨会,讨论数据受限的物理生物地球化学模型的实用性,这些活动将促进美国与格陵兰的研究合作。在美国,该项目支持早期职业科学家的职业发展,并将通过鼓励年轻女性追求北极海洋科学的外展活动培养多元化的 STEM 劳动力队伍。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准。
