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从这项主要研究工具（MRI）计划拨款中进行的1530560助理将使早期的职业研究员能够获取和部署一种新型的远程操作/自动级别的浅水水域映射系统，用于在河流，湖泊，湖泊和远程地点进行水文测量，而传统调查容器无法获得传统的测量容器。 无人的地表船（USV）由Teledyne制造，长1.8 m，具有双支架，并将配备多束声纳，这是一个实时运动学（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计划和数据分析软件。 USV作为配备的能力提供了用CM尺度分辨率绘制测深的能力，尤其是在传统调查船无法运行的浅水系统中（例如，前冰湖，浅水入口，河口，河口和沿冰期河流）。 通过随着时间的流逝，研究者将在影响人群的环境中获得对河流沉积物传输，床形和三角洲进化的深入了解。 许多研究人员的映射目标从未受过调查，因此获得的知识具有变革性的潜力，因此支持NSF的使命促进科学的进步。 本科大学的本科生将使用USV进行体验式领域映射，从而增加了通常从事水文测量并促进国家福利的领域的就业能力。
