Marine Corps Base Camp Lejeune CW-5 Marsh Carbon, Nutrient and Atmospheric Gas exchanges with overlying water

Critical military training and testing on lands along the nation’s coastal and estuarine shorelines are increasingly placed at risk because of encroachment pressures in surrounding areas, impairments due to other anthropogenic disturbances, and changes in climate and sea level. The U.S. Department of Defense (DoD) intends to enhance and sustain its training and testing assets and also optimize its stewardship of natural resources through the development and application of an ecosystem-based management approach on DoD installations. To accomplish this goal, particularly for installations in estuarine/coastal environments, the Strategic Environmental Research and Development Program (SERDP) launched the Defense Coastal/Estuarine Research Program (DCERP) as a 10-year effort at Marine Corps Base Camp Lejeune (MCBCL) in North Carolina. The results of the second 5 years of the program (DCERP2) are presented in the DCERP2 Final Report. There were four overarching objectives of DCERP2. The first objective was to understand the effects of climate change impacts, including warming temperatures, variability in the hydrological cycle, storm events, and sea level rise on the coastal ecosystems at MCBCL from observations and measurements made over the 10-year program. The second objective was to understand the carbon cycle of the coastal and terrestrial ecosystems at MCBCL through a highly integrated sampling program. The third objective was to develop models, tools, and indicators to evaluate current and projected future ecosystem state changes and translate scientific findings into actionable information for installation managers. The last objective was to recommend adaptive management strategies to sustain ecosystem natural resources within the context of an active military installation. This dataset represents the results of seasonal samplings of triplicate paired fertilized and control plots across three marsh sites at Camp Lejeune Marine Corps Base, NC. It was used to compare chemical characteristics and processes across the three locations to determine the factors driving the response of salt marsh sustainability to fertilization.

国家沿海与河口岸线沿线区域的军事训练与试验活动，正日益面临周边区域侵占压力、其他人为干扰造成的生态损害，以及气候与海平面变化带来的风险。
美国国防部（U.S. Department of Defense, DoD）计划通过在其军事设施内开发并应用基于生态系统的管理方法，强化并维持其训练与试验资产，同时优化自然资源管护工作。
为实现这一目标，尤其是针对河口/沿海环境中的军事设施，战略环境研究与发展计划（Strategic Environmental Research and Development Program, SERDP）在北卡罗来纳州的勒琼海军陆战队基地（Marine Corps Base Camp Lejeune, MCBCL）启动了为期10年的国防沿海/河口研究计划（Defense Coastal/Estuarine Research Program, DCERP）。
该计划第二个五年阶段（DCERP2）的研究成果收录于《DCERP2最终报告》中。DCERP2共设定四项核心目标：其一，基于10年计划期间的观测与测量数据，解析气候变化（包括气温升高、水文循环变异、风暴事件以及海平面上升）对MCBCL沿海生态系统的影响；其二，通过高度集成的采样计划，阐明MCBCL沿海与陆地生态系统的碳循环过程；其三，开发用于评估当前及预测未来生态系统状态变化的模型、工具与指标，并将科学研究成果转化为可供设施管理人员使用的可落地信息；其四，针对活跃军事设施的运营场景，提出可持续维持生态系统自然资源的适应性管理策略。
本数据集涵盖北卡罗来纳州勒琼海军陆战队基地内3处沼泽站点的季节性采样结果，采样对象为三组重复的施肥样地与对照样地配对组合。本数据集用于对比三处站点的化学特征与生态过程，以明确调控盐沼可持续性对施肥措施产生响应的关键驱动因子。
