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.

该项目旨在分析在前往罗塔 1 号（西太平洋海底火山喷发）的航行中收集的数据。这项工作没有在上一个奖项中得到资助，代表了由新安装的、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序列进行成像。数据分析将包括提取喷发羽流信息以及其高度、强度和方向如何随时间变化。它还会将中层水羽流结果与 ROV 目视观测结果进行比较。该研究的主要部分将致力于衡量中层多波束气泡序列数据集的有用性，并找出在衡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新 UNOLS 仪器功能的开发。
