This project seeks to analyze data collected on a cruise of exploration to Rota 1, an erupting undersea volcano in the western Pacific ocean. The work was not funded in the previous award and represents new data collected by a newly installed, more capable, multibeam sonar tool that can image bubble trains in with water column. Analysis of the data will include extracting eruption plume information and how it changes with time in terms of height, intensity, and direction. It will also compare the mid-water plume results to ROV visual observations. A major part of the study will be devoted to gauging the usefulness of mid-water multibeam bubble train datasets and finding out what can be learned from them in terms of gauging an undesea volcano's activity. Broader impacts of the work include graduate student training and development of a new UNOLS instrument capability.

该项目旨在分析在西太平洋海底火山喷发的Rota 1号的探测巡航中收集的数据。这项工作没有在之前的合同中得到资助，它代表了新安装的、功能更强大的多波束声纳工具收集的新数据，该工具可以对水柱中的气泡列车进行成像。对数据的分析将包括提取喷发羽流信息，以及它在高度、强度和方向上如何随时间变化。它还将把水中羽流的结果与ROV目视观测结果进行比较。这项研究的一个主要部分将致力于测量水中多波束气泡列数据集的有用性，并找出在测量海底火山活动方面可以从中学到什么。这项工作的更广泛影响包括研究生培训和发展联卢观察团新的仪器能力。
