NAICEX Data Archive from Barrow Landfast Ice Survey

This section of the archive covers the Ice Survey conducted off the coast of Barrow Alaska in March 2013. A single transect was created as a ground truth line from which NASA IceBridge and NRL airborne missions could calibrate their instruments. The US Naval Academy team lead by LCDR John Woods was chief scientist for NAICEX. Two faculty and three students from the University of Delaware (UD) worked on the ice under the coordination of John Woods to collect ice survey data to support education and field exercises for Navy Cadets. CDR Angela Walker under Admiral White was present for three days to evaluate these exercises and promote future educational exercises. The UD portion was pulled together under an extremely tight budget with only two months to prepare, but that team performed very well and was able to bring together a small but very effective survey exercise involving the following simple instruments: Surveying of sea ice topography with polar grade TopCon Survey Gun GIS mapping of large scale events with ArcGIS software Electromagnetic Induction (EMI) profiling of sea ice thickness Drill hole validations These four data sets are included here with forthcoming papers on new EMI calibrations coming shortly through the Ph.D. doctoral work of Jesse P. Samluk; the Ph.D. student supported through this project.

本档案板块涵盖2013年3月在阿拉斯加州巴罗（Barrow）沿海开展的海冰勘测项目。本次勘测设置了一条单一断面测线作为地面真值（ground truth）基准线，供NASA冰桥行动（NASA IceBridge）与美国海军研究实验室（NRL）的机载任务团队校准仪器使用。由海军少校（LCDR）约翰·伍兹（John Woods）带领的美国海军学院团队担任了NAICEX的首席科学家。特拉华大学（UD）的2名教职人员与3名学生在约翰·伍兹的协调下于冰面开展作业，采集海冰勘测数据，用于支撑海军学员的教学与野外实训任务。由怀特海军上将管辖的海军指挥官（CDR）安吉拉·沃克（Angela Walker）莅临现场三日，对本次实训进行评估，并推动后续相关教学实训项目的开展。特拉华大学团队的筹备工作预算极为紧张，且仅用两个月时间完成筹备，但团队表现优异，成功组织了一场规模不大却成效显著的勘测实训，所用简易仪器如下：1. 采用极地级拓普康测量枪（TopCon Survey Gun）开展海冰地形测绘；2. 借助ArcGIS软件完成大规模事件的地理信息系统（GIS）制图；3. 通过电磁感应（EMI）剖面测量海冰厚度；4. 实施钻孔验证。本次归档包含上述四组数据集，依托本项目资助的博士生杰西·P·萨穆卢克（Jesse P. Samluk）将基于其博士研究成果，近期发表关于新型电磁感应校准方法的学术论文。
