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

PI申请资金是为了获得高分辨率的水深测绘能力，通过采购多波束声纳和平移和倾斜执行器。这些项目结合在一起，将为复杂的水下场景创造一种不同于科学界使用的其他交通工具的多功能测绘能力。这些仪器将提供一种多标量视觉和声学测绘的手段，从一平方公里的10厘米精度到数百平方米的毫米精度。高分辨率的深海地图已经成为海洋考古学和海洋学，特别是海洋地质学研究的重要工具。有效绘制水深图的能力将使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。这些工具还将完成测绘传感器套件，并极大地促进开发机器人测绘技术的补充工程努力。所要求的项目将使PI能够利用平移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，并开发用于创建海底3D纹理映射表示的方法。更广泛的影响：此次收购将进一步推动一个广泛的外展计划，重点关注科学与技术之间的联系。技术和数据将被纳入“海上教育者”计划和“鹦鹉螺”计划的公共宣传部门。这提供了与公众接触的能力，并为K-12教师提供了经验。鹦鹉螺计划为理工科学生提供了大量的教育和培训。URI的学生与合作院校之间将建立伙伴关系。深海测量数据也将通过鹦鹉螺号的医生随叫随到计划提供给海洋学界。pi历来为代表性不足的群体提供参与机会，通过Nautilus项目将继续提供这样的机会。海底勘探的实时互动广播为广泛参与提供了极好的机会，即使每个人都不能与pi一起在偏远地区的船上。通过探索和了解我们的环境的技术进步，以及通过pi工作的人类学/考古学性质，可能会实现对社会的好处。

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.
