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).

这是一个研究佛罗里达沼泽地碳平衡以及气候变化、水文和盐水入侵的交互影响的更新项目。这一努力支持了对大沼泽地国家公园淡水沼泽地区2个地点的二氧化碳和甲烷浓度以及水和能量通量的持续大气观测。从另外两个站点收集的数据将使科学调查人员能够扩大到区域水平，并更好地开发预测模型，以估计大沼泽地未来生态系统的温室气体碳平衡。这四个研究站点与佛罗里达沿海大沼泽地长期生态研究（FCE-LTER）站点位于同一地点，代表了公园沼泽和红树林生态系统的强烈梯度。这项工作还将有助于通过NSF支持的国家生态观测网络（氖）计划，国家公园服务，南佛罗里达水管理区（SFWMD）和美国地质调查局（USGS）进行的研究。
