Marine Corps Base Camp Lejeune Geospatial Marsh Model: Elevation Maps

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 data package contains PNGs of elevation maps (w/ scale bars) for Freeman, Trapps, and French marsh modeling domains in the target years 2013 (initial), 2035, 2065, & 2100 after modeling marsh under the five sea level rise (SLR) scenarios provided by the base.

美国沿海与河口沿岸地带的关键军事训练与测试活动正面临日益加剧的风险，其诱因包括周边区域的侵占压力、其他人为活动造成的生态破坏，以及气候与海平面变化。美国国防部（U.S. Department of Defense, DoD）旨在通过在其军事设施中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测试资产，同时优化自然资源管理工作。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热纳海军陆战队基地（Marine Corps Base Camp Lejeune, MCBCL）启动了为期十年的国防沿海/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：第一项目标是基于十年计划期间的观测与测量数据，解析气候变化影响——包括气温升高、水文循环变异、风暴事件以及海平面上升——对勒热纳海军陆战队基地沿海生态系统的作用机制；第二项目标是通过高度集成的采样计划，探明勒热纳海军陆战队基地沿海与陆地生态系统的碳循环过程；第三项目标是开发模型、工具与指标，用于评估当前及预测未来的生态系统状态变化，并将科学研究成果转化为可供军事设施管理者使用的可落地信息；第四项目标是提出适应性管理策略，在现役军事设施的运营框架内维持生态系统自然资源的可持续性。

本数据包包含针对弗里曼（Freeman）、特拉普斯（Trapps）以及弗伦奇（French）沼泽建模区域的高程图（带比例尺），该模型基于该基地提供的五种海平面上升（Sea Level Rise, SLR）情景对沼泽进行模拟，生成了2013年（初始基准年）、2035年、2065年及2100年四个目标年份的高程图PNG文件。
