Approximately 50% of the U.S. population lives within 80 km of a coast. As human populations proximal to coasts increase, demands for the natural resources and services that coastal ecosystems provide will also grow, further stressing these ecosystems. The Florida Coastal Everglades LTER (FCE) is an excellent laboratory for understanding how coastal ecosystem dynamics respond to, and influence, human activities. Oligotrophy is a defining characteristic of FCE, and the estuaries of the study area are biogeochemically upside down because the source of limiting nutrients is the ocean, not the watershed. The conceptual approach for FCE II is evolutionary, with emphases on oligohaline ecotone dynamics; hydrologic, climatological, and human drivers that affect those dynamics; and processes that regulate biophysical inputs to the ecotone from upstream freshwater Everglades marshes and the estuary proper. The overarching theme of FCE II follows this evolution of ideas: In the coastal Everglades landscape, population and ecosystem-level dynamics are controlled by the relative importance of water source, water residence time, and local biotic processes. This phenomenon is best exemplified in the oligohaline ecotone, where these factors interact most strongly and vary over many temporal and spatial scales. FCE will continue tracking the flow of water from canals to the ocean along two transects in Everglades National Park. Several new initiatives include new research hydrology (particularly groundwater hydrology) and human dimensions. Everglades Restoration is the experimental, BACI-style template for FCE; in this next round of funding a major restoration project will remove a key levee at the head of one of the transects. This grand experiment will cause a considerable increase in freshwater flow to only one transect, and central hypotheses are directed at understanding the results of this major change.FCE II will continue its close involvement with the many existing modeling efforts in south Florida to avoid redundancies and will expand its dynamic budget simulation modelling to the ecotone regions, thus filling a critical between-ecosystem simulation gap. Finally, FCE II will continue to carefully balance continuity (critical to any successful long-term program) with support for new ideas and initiatives by expanding program leadership to include both FCE I PIs and rising star junior faculty.FCE is based at FIU, a majority-minority public university that is one of the largest Hispanic-serving institutions in the U.S. The FCE student group is large, active, and diverse. The FCE K-12 program, in which 89% of all students impacted are Hispanic, will be strengthened by including new high school curriculum development and enhanced mentoring. Outreach to the South Florida community (which is over 60% Hispanic) will become fully bilingual. The user-friendly, information-rich FCE website will continue to be the primary outreach portal. FCE II will further the goal of linking FCE science with Everglades Restoration to provide reliable, continuous and growing knowledge transfer from basic ecological theory to the development of more effective environmental management and restoration/rehabilitation programs.

大约50%的美国人口居住在距离海岸80公里的范围内。随着靠近海岸的人口增加，对沿海生态系统提供的自然资源和服务的需求也将增加，从而进一步加重这些生态系统的压力。佛罗里达沿海大沼泽地LTER（FCE）是了解沿海生态系统动态如何响应和影响人类活动的优秀实验室。寡营养是FCE的一个定义特征，研究区域的河口是生态地球化学颠倒的，因为限制营养物质的来源是海洋，而不是流域。FCE II的概念方法是渐进的，重点是寡盐生态交错带动态;水文，气候和人类的驱动因素，影响这些动态;和过程，调节生物物理输入的生态交错带从上游淡水沼泽地沼泽和河口。FCE II的总体主题遵循这种思想的演变：在沿海沼泽地景观中，人口和生态系统水平的动态受到水源，水停留时间和当地生物过程的相对重要性的控制。这一现象在寡盐交错带最能说明问题，在那里，这些因素相互作用最强烈，并在许多时间和空间尺度上变化。FCE将继续追踪大沼泽地国家公园内沿着两条横断面从运河流向海洋的水流。一些新的倡议包括新的水文学研究（特别是地下水水文学）和人的方面。大沼泽地恢复是实验性的，BACI风格的模板FCE;在下一轮的资金，一个主要的恢复项目将删除一个断面的头部的关键堤坝。这个大实验将导致相当大的增加，淡水流量只有一个样带，和中央的假设是针对理解这一重大变化的结果。FCE II将继续密切参与与现有的许多建模工作在南佛罗里达，以避免冗余，并将其动态预算模拟模型的生态交错区，从而填补了关键的生态系统之间的模拟差距。最后，FCE II将继续仔细平衡连续性（对任何成功的长期计划至关重要），通过扩大计划领导，包括FCE I PI和冉冉升起的星星初级教师，支持新的想法和举措。FCE总部设在佛罗里达国际大学，一所以少数族裔为主的公立大学，是美国最大的西班牙裔服务机构之一。FCE K-12计划，其中89%的受影响学生是西班牙裔，将通过包括新的高中课程开发和加强辅导来加强。对南佛罗里达社区（超过60%的西班牙裔）的宣传将完全双语化。方便用户、信息丰富的教育基金会网站将继续作为主要的外联门户。FCE II将进一步实现将FCE科学与大沼泽地恢复联系起来的目标，以提供从基本生态理论到更有效的环境管理和恢复/恢复计划的发展的可靠，持续和不断增长的知识转移。
