MRI: Acquisition of a BlueView Technologies Multibeam Sonar System for High-resolution Vehicle-based Sea Floor Mapping

国际和平研究所要求提供资金，通过购置一个多波束声纳和一个摇摄和倾斜致动器来获得高分辨率的测深能力。这些项目结合在一起，将为复杂的水下场景创造一种多才多艺的绘制能力，有别于科学界使用的其他工具。这些仪器将提供一种在从10‘S厘米精度的平方公里到毫米精度的数百平方米的比例尺上进行多标度视觉和声音测绘的手段。高分辨率水深图已成为研究海洋考古学和海洋学，特别是海洋地质学的重要工具。高效绘制水深地图的能力将使PI能够更好地了解潜水地点的地质景观，并为收集的样本提供背景。这些工具还将完成一整套测绘传感器，并极大地促进开发机器人测绘技术的补充工程工作。所要求的项目将使PI能够利用摇摄和倾斜执行器提供的自由适当地绘制完全垂直和复杂的水下场景，并开发创建海底3D纹理映射表示的方法。广泛的影响：此次收购将进一步推进一个广泛的外联计划，重点放在科学和技术之间的联系上。技术和数据将被纳入海上教育者方案和鹦鹉螺方案的公共宣传部门。这为普通公众提供了参与的能力，并为K-12教师提供了经验。Nautilus项目包含了针对理工科学生的大量教育和培训工作。将在URI的学生和合作机构之间建立伙伴关系。水深测量数据也将通过鹦鹉螺号的随叫随到医生计划提供给海洋学社区。私人投资机构有为代表不足的群体提供参与机会的历史，并将通过鹦鹉螺方案继续提供这种机会。海底勘探的实时互动广播为广泛参与提供了极好的机会，即使不是每个人都能带着PI在偏远地点上船。对社会的益处很可能体现在探索和了解我们环境的技术进步中，以及通过许多个人资料工作的人类学/考古学性质。

The PI's request funding to obtain a high resolution bathymetric mapping capability through the acquisition of a multibeam sonar and a pan and tilt actuator. Together these items will create a versatile mapping capability for complex underwater scenes distinct from other vehicles used by the scientific community. These instruments will provide a means for multiscalar visual and acoustic mapping over scales from a square kilometer with 10's of cm accuracies down to hundreds of square meters with millimeter accuracy. High resolution bathymetric maps have become essential tools for the study of marine archaeology and oceanography, particularly marine geology. The ability to efficiently make bathymetric maps will enable the PI's to better understand the geological landscape of dive sites and provide a context for collected samples. These tools will also complete the suite of mapping sensors and greatly facilitate complementary engineering effort of developing techniques for robotic mapping. The requested items will give the PI's the capability to mapping fully vertical and complex underwater scenes appropriately using the freedom provided by the pan and tilt actuator and develop methodologies for creating 3D texture mapped representations of the seafloor.Broader Impacts: The acquisition will further an extensive outreach program which focuses on the link between science and technology. Techniques and data will be incorporated into the Educator-At-Sea program and the public outreach arm of the Nautilus Program. This provides the ability to engage the general public and provide experiences to K-12 teachers. The Nautilus program incorporates a large education and training effort for science and engineering students. Partnerships will be developed between students at URI and collaborative institutions. Bathymetric data will also be made available to the oceanographic community through the Nautilus' Doctors-on-call program. The PIs have a history of participation opportunities for underrepresented groups and through the Nautilus program will continue to provide such opportunities. The real-time interactive broadcast of seafloor exploration provides excellent opportunities for broad participation even if everyone is not able to be on the ship in remote locations with the PIs. Benefits to society will likely be realized both in technological advances towards exploring and understanding our environment and through the anthropological/archaeological nature of much of the PIs work.
