项目摘要

Ocean waters are infiltrating and influencing freshwater-dependent coastal landscapes due to a combination of human and natural factors. By the end of this century, lower-lying parts of the outer edge of the Southern U.S. coastal plain will be largely inundated by saltwater due to gradual sea level rise. The salinization of surface waters and adjacent lands may lead to significant reductions in crop and timber yields in managed ecosystems, significant declines in ecosystem carbon sequestration in unmanaged ecosystems, and degradation of coastal water quality due to extraction of soil nutrients by seasalts. This project will enhance understanding of the coupled human and natural processes influencing salinization of surface waters and adjacent lands. Investigators will build and engage a coalition of expert stakeholders, including members of state and local governments, regional planning groups, landowners and advocacy organizations. Partnerships with stakeholders will help investigators define the current status of coastal ecosystems, identify critical knowledge gaps, share new research findings, and develop and explore future land use and climate scenarios. This project will yield outcomes with predictive value in coastal systems that are easily understood by stakeholders while representing complex interactions between climate, hydrology, land use, and ecological processes and identify pathways by which outcomes could be used to enhance coastal sustainability. Together, these activities will help guide sustainable management of this region and similarly affected regions over the next several decades to centuries. Additional broader impacts include training four Ph.D. students in interdisciplinary research that spans natural and social sciences, engaging undergraduate students in mentored research experiences, and broadening participation of underrepresented groups in the sciences by supporting early career investigators and working to recruit students from underrepresented groups. This project is supported as part of the National Science Foundation's Coastal Science, Engineering, and Education for Sustainability program - Coastal SEES.This project focuses on saltwater intrusion, the landward movement of salinity from the coast onto the coastal plain. A team of investigators representing four disciplines (hydrology, biogeochemistry, community ecology, regional planning) will integrate social, hydrological, climate and ecological data into model scenarios to examine not only how human decisions affect ecosystems but also how information about those ecological impacts in turn affect human decisions. This project will facilitate development, validation and refinement of a saltwater intrusion vulnerability index (SIVI) for the Albemarle-Pamlico peninsula of North Carolina that accounts for physical environmental processes influencing the movement of water and solutes across the landscape as well as the extensive networks of canals, ditches, roads and pump stations that fundamentally alter the flow of water across the region. The index will be used, along with extensive and repeated ground-based surveys of surface water, soil and vegetation conditions across a range of vulnerable landscapes within the region, to better understand ecological impacts of saltwater intrusion. Through workshops and surveys for landowners, managers and other stakeholders in the region, the project will reveal the likely impact of land-use decisions on saltwater intrusion under scenarios of climate change.
由于人为和自然因素的共同作用,海水正在渗透并影响依赖淡水的沿海景观。到本世纪末,由于海平面逐渐上升,美国南部沿海平原外缘的低洼地区将大部分被咸水淹没。地表水和邻近土地的盐化可能导致受管理的生态系统中农作物和木材产量大幅下降,未受管理的生态系统中生态系统碳固存显着下降,以及由于海盐提取土壤养分而导致沿海水质恶化。 该项目将加深对影响地表水和邻近土地盐化的人类和自然过程的了解。调查人员将建立并吸引专家利益相关者联盟,包括州和地方政府成员、区域规划团体、土地所有者和倡导组织。与利益相关者的合作将帮助研究人员确定沿海生态系统的现状,确定关键的知识差距,分享新的研究成果,并开发和探索未来的土地利用和气候情景。该项目将在沿海系统中产生具有预测价值的成果,这些成果易于被利益相关者理解,同时代表气候、水文、土地利用和生态过程之间复杂的相互作用,并确定可利用成果来增强沿海可持续性的途径。 这些活动将共同帮助指导该地区和类似受影响地区在未来几十年到几个世纪的可持续管理。 其他更广泛的影响包括培训四名博士。学生参与自然科学和社会科学的跨学科研究,让本科生参与指导性的研究经历,并通过支持早期职业调查人员和努力从代表性不足的群体中招募学生来扩大代表性不足的群体在科学领域的参与。 该项目是国家科学基金会沿海科学、工程和可持续发展教育计划 - 沿海 SEES 的一部分。该项目的重点是咸水入侵,即盐度从海岸向陆地移动到沿海平原。代表四个学科(水文学、生物地球化学、群落生态学、区域规划)的研究小组将把社会、水文、气候和生态数据整合到模型场景中,不仅研究人类决策如何影响生态系统,而且研究有关这些生态影响的信息又如何影响人类的决定。 该项目将促进北卡罗来纳州阿尔伯马尔-帕姆利科半岛咸水入侵脆弱性指数(SIVI)的开发、验证和完善,该指数考虑了影响水和溶质在整个景观中的运动以及广泛的海水入侵网络的物理环境过程。运河、沟渠、道路和泵站从根本上改变了该地区的水流。 该指数将与对该地区一系列脆弱景观的地表水、土壤和植被条件进行广泛和重复的地面调查一起使用,以更好地了解咸水入侵的生态影响。 通过为该地区的土地所有者、管理者和其他利益相关者举办研讨会和调查,该项目将揭示气候变化情景下土地利用决策对盐水入侵可能产生的影响。
