Marine Corps Base Camp Lejeune Washover Fan Morphology Summer 2013

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 grid file was created from data collected using a Riegl 3-D laser scanner. Millions of x, y, and z points from the F2 Washover Fan on Onslow Beach were processed using the MARS software package to define a bare-earth model. These data were collected to quantify the morphological changes that occur on a washover fan through time.

沿美国海岸与河口岸线开展的重要军事训练与测试活动，正日益面临周边区域侵占压力、其他人为活动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）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模式，强化并维持其训练与测试资产，同时优化对自然资源的管理职责。为达成这一目标，尤其是针对河口与海岸环境中的军事设施，战略环境研究与发展计划（Strategic Environmental Research and Development Program, SERDP）在北卡罗来纳州勒热纳海军陆战队基地（Marine Corps Base Camp Lejeune, MCBCL）启动了为期10年的国防海岸与河口研究计划（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共设有四项核心目标：第一项目标为基于10年计划周期内的观测与测量数据，解析气候变化对MCBCL海岸生态系统的影响，包括气温升高、水文循环变异、风暴事件以及海平面上升；第二项目标为通过高度集成的采样计划，探明MCBCL海岸与陆地生态系统的碳循环过程；第三项目标为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者使用的可操作信息；第四项目标为提出适应性管理策略，以在现役军事设施的运营背景下维持生态系统自然资源的可持续性。本网格文件由Riegl 3-D激光扫描仪（Riegl 3-D laser scanner）采集的数据生成。研究人员使用MARS软件包（MARS software package）对昂斯洛海滩（Onslow Beach）F2冲溢扇（F2 Washover Fan）的数百万个x、y、z三维点云数据进行处理，以构建裸地表层模型。本次数据采集旨在量化冲溢扇随时间推移发生的地貌形态变化。
