This is a renewal project to study carbon balance in the Florida everglades and the interactive effects of climate change, hydrology, and saltwater intrusion. This effort supports continued atmospheric observations of carbon dioxide and methane concentrations, and water and energy fluxes at 2 sites in the freshwater marsh regions of Everglades National Park. The collection of data from 2 additional sites will allow the science investigators to scale up to a regional level and to better develop predictive models to estimate future ecosystem greenhouse carbon balance in the Everglades.The four study sites are co-located with Florida Coastal Everglades Long Term Ecological Research (FCE-LTER) sites and represent the strong gradients found in marsh and mangrove ecosystems of the Park. This work will also contribute to research being conducted through the NSF-supported National Ecological Observatory Network (NEON) Program, the National Park Service, the South Florida Water Management District (SFWMD), and the United States Geological Survey (USGS).

这是研究佛罗里达大沼泽地的碳平衡以及气候变化，水文学和盐水侵入的互动效应的续签项目。这项工作支持对二氧化碳和甲烷浓度的持续大气观察，以及在淡水沼泽国家公园的淡水沼泽地区的两个地点的水和能量通量。来自两个其他站点的数据收集将使科学研究人员可以扩展到区域水平，并更好地开发预测模型，以估计Everglades中未来的生态系统温室碳平衡。四个研究地点与佛罗里达沿海长绿色长期生态研究（FCE-ter）站点（FCE）站点（FCE）站点（FCE）站点（FCE-lter）站点（FCE）站点，并在Marsh和Mangredecy Sparkscrey Sparksrove Spartsrove Sparksrove Spartsroude parks. Ecosystemss中，该地点逐渐渐变。这项工作还将有助于通过NSF支持的国家生态观测网络（NEON）计划，国家公园管理局，南佛罗里达水管理区（SFWMD）和美国地质调查局（USGS）进行研究。
