CoPe EAGER: Multi-Scale Exploration of Nutrient Cycles and its Socio-Economic Impacts in Coastal Areas

表层和海洋沃茨中过量的营养物导致营养物污染，这是美国60%以上的沿海河流、海湾和海洋水质退化的原因。随着营养物的持续供应，某些浮游植物物种在独特的环境条件下会变得不成比例地丰富，形成通常所称的“赤潮”。据估计，美国每年赤潮造成的经济影响至少为数千万美元。当务之急是减少赤潮风险，提高沿海社区的相关复原力。该项目的研究成果将通过与公众的联系以及与县、州和联邦机构的研究人员、从业人员和决策者的合作，向多个社区的广大受众传播。该项目将支持两名本科生和一名博士后研究员，他们将从科学界代表性不足的群体中招募。该项目将跨越陆地和海洋系统之间的海岸线界限，以及地球科学、自然科学和社会科学之间的学科界限，开展创新的跨学科研究。本项目将探索能量亿级地球系统模型（E3SM），用于模拟从陆地系统到海洋系统的营养盐通量，并将E3SM模拟的营养盐通量与赤潮发生联系起来，以支持社会经济影响评估。本项目的目标是探索E3SM是否可以作为一种新的软件，用于模拟多尺度的营养盐通量，以估计赤潮的发展和持续性，并评估各种环境和管理情景下的赤潮的社会经济影响。此外，研究小组还将评估E3SM是否可以作为促进沿海管理的社区工具。佛罗里达州已被选为该项目的主要研究地点，但该模型可用于沿着美国海岸线。E3SM及其在营养物污染研究和社会经济影响评估中的应用可以成为沿海研究人员、决策者、从业者和利益相关者解决沿海营养物污染问题的新兴软件基础设施。该奖项反映了NSF的法定使命，并被认为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来支持。

Excessive nutrients in surface and ocean waters cause nutrient pollution, which is responsible for water quality degradation in more than 60% of coastal rivers, bays, and seas in the U.S. With a continuous nutrient supply, certain phytoplankton species can become disproportionately abundant under distinctive environmental conditions, forming what is commonly known as "red tides". The economic impacts of red tides in the U.S. are estimated to be at least tens of million dollars per year. It is imperative to reduce the risk of red tides and to increase the associated resilience of coastal communities. Research results of this project will be disseminated to a broad audience in multiple communities through outreach to the public and by collaborating with researchers, practitioners, and decision-makers in county, state and federal agencies. This project will support two undergraduate students and one postdoctoral researcher who will be recruited from underrepresented groups in science. The PIs will incorporate the research results into their classroom teaching and curriculum development.This project will conduct innovative interdisciplinary research across the coastline boundary between terrestrial and ocean systems and across the disciplinary boundaries between geosciences, natural, and social sciences. This project will explore the Energy Exascale Earth System Model (E3SM) for simulating nutrient fluxes from a terrestrial system to an ocean system and for linking E3SM-simulated nutrient fluxes to red tide occurrence in support of socio-economic impact assessment. The goal of this project is to explore whether E3SM can be used as a new software to simulate nutrient fluxes at multiple scales for estimating red tide development and persistence and for assessing socio-economic impacts of red tides under various environmental and management scenarios. Additionally, the research team will evaluate whether E3SM can be used as a community tool to facilitate coastal management. The State of Florida has been chosen as the primary study site for this project, yet the model can be used along the US coastline. E3SM and its uses for nutrient pollution study and socio-economic impact assessment can be an emerging software infrastructure for coastal researchers, decision-makers, practitioners, and stakeholders to address coastal nutrient pollution problems.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.
