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.

1530560 Shugar从这个主要研究仪器（MRI）计划补助金的资金将使早期的职业调查人员能够获得和部署一种新型的远程操作/自主浅水水深测绘系统，用于河流，湖泊和传统测量船无法到达的偏远地区的水文测量。 无人水面舰艇（USV）由Teledyne制造，长1.8米，有双支柱，将配备多波束声纳，实时动态（RTK）全球导航卫星系统（GNSS）接收器和惯性测量单元（IMU）。 操作系统将包括调查规划和数据分析软件。 配备的USV提供了以厘米级分辨率绘制水深测量图的能力，特别是在传统测量船无法操作的浅水系统（例如冰前湖、浅水湾、河口和冰前河）。 随着时间的推移，通过使用重复绘图，研究人员将获得对影响人类人口的环境中的河流沉积物搬运、床形和三角洲演变的深入了解。 许多绘制目标的调查人员以前从未进行过调查，因此获得的知识有可能是变革性的，因此支持NSF促进科学进步的使命。 这所以本科为主的大学的本科生将使用USV进行经验性实地测绘，提高常规从事水文测量的领域的就业能力，从而促进国家福利。
