Onslow Beach Washover Fan Morphology from 2012 to 2015

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. These grid files were 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. Grid files were imported into Golden Software Surfer version 19 for editing and exported from that application as .grd files. Files can be opened in Surfer or ArcMap, but the coordinate system information will be lost if opened in ArcMap. These data were collected to quantify the morphological changes that occur on a washover fan through time.

美国沿海及河口海岸沿线区域的重要军事训练与试验活动正日益面临风险，威胁来源包括周边区域的侵占压力、其他人为干扰造成的生态损害，以及气候与海平面变化。美国国防部（U.S. Department of Defense, DoD）计划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共包含四项核心目标：第一项目标为基于10年研究周期内的观测与测量数据，解析气候变化（包括气温升高、水文循环变异、风暴事件及海平面上升）对MCBCL沿海生态系统的影响；第二项目标为通过高度整合的采样计划，明晰MCBCL沿海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、工具与指标体系，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决策信息；第四项目标为针对现役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。本次的网格文件由Riegl三维激光扫描仪（Riegl 3-D laser scanner）采集的数据生成：昂斯洛海滩（Onslow Beach）F2冲溢扇的数百万个x、y、z坐标点经MARS软件包（MARS software package）处理，以构建裸地模型；网格文件导入Golden Software Surfer 19版本进行编辑，并以.grd格式从该软件导出。此类文件可在Surfer或ArcMap中打开，但在ArcMap中打开时会丢失坐标系信息。采集本数据集旨在量化冲溢扇随时间推移发生的形态变化。
