MRI: ACQUISITION OF A SHALLOW-WATER AUTONOMOUS MULTIBEAM HYDROGRAPHIC SURVEYING SYSTEM

1530560ShugarFunding来自这项重大研究仪器(MRI)计划赠款，将使职业生涯早期的调查员能够获得和部署一种新型的远程操作/自主的浅水水深测绘系统，用于传统勘测船无法到达的河流、湖泊和偏远地点的水文测量。无人水面舰艇(USV)由Teledyne制造，长1.8米，有两个螺旋桨，将配备一个多波束声纳、一个实时运动学(RTK)全球导航卫星系统(GNSS)接收器和一个惯性测量单元(IMU)。该操作系统将包括调查规划和数据分析软件。配备的USV能够以厘米级的分辨率绘制水深图，特别是在传统勘测船无法作业的浅水系统(例如，冰川湖泊、浅水湾、河口和冰川河流)。通过使用随时间推移的重复绘图，研究人员将对影响人类种群的环境中的河流沉积物运移、河床形态和三角洲演变有一个更深入的了解。许多绘制目标地图的调查人员以前从未被调查过，因此所获得的知识具有变革的潜力，因此支持美国国家科学基金会促进科学进步的任务。这所以本科为主的大学的本科生将使用USV从事体验式野外测绘，增加常规从事水文测量的领域的就业能力，从而促进国家福利。

1530560ShugarFunding from this Major Research Instrumentation (MRI) Program grant will enable an early career investigator to acquire and deploy a novel remotely operated/autonomous shallow water bathymetric mapping system for hydrographic surveying in rivers, lakes and remote locations inaccessible to traditional survey vessels. The unmanned surface vessel (USV) is manufactured by Teledyne, is 1.8 m long, has twin props and will be outfitted with a multibeam sonar, a real-time kinematic (RTK) Global Navigation Satellite System (GNSS) receiver and an inertial measurement unit (IMU). The operating system will include survey planning and data analysis software. The USV as equipped offers the capability to map bathymetry with cm-scale resolution especially in shallow water systems where traditional survey vessels cannot operate (e.g. proglacial lakes, shallow inlets, estuaries and proglacial rivers). By using repeat mapping over time the investigator will gain an advanced understanding of fluvial sediment transport, bedform and delta evolution in environments that impact human populations. Many of the investigators mapping targets have never before been surveyed so the knowledge gained has the potential to be transformative and therefore supports NSF mission of promoting the progress of science. Undergraduates at this predominantly undergraduate university will be engaged in experiential field mapping using the USV, increasing employability in fields that routinely engage in hydrographic surveying and thus promoting the national welfare.
