AUV Sentry dive navigation and along-track data at Axial Seamount (TN383, 2020)

A research cruise to Axial Seamount was conducted in 2020 with ROV Jason II and AUV Sentry during Thompson cruise TN383 (chief scientist Bill Chadwick). A total of seven AUV Sentry dives were conducted in and around the seamount. These Sentry navigation data files are sampled at 1Hz and provided here as comma-separated SCC-like-formatted ASCII text files, with column headers. The navigation data was re-navigated post-dive to combining USBL acoustic navigation with DVL information. The data set was collected and processed as part of the project called Advancing Deformation Monitoring Methods at Axial Seamount. Funding was provided from NSF awards OCE17-36882, OCE17-36926, OCE17-37019.

2020年，在Thompson号航次TN383（首席科学家为Bill Chadwick）框架下，科研人员搭载遥控无人潜水器（Remotely Operated Vehicle, ROV）Jason II与自主水下航行器（Autonomous Underwater Vehicle, AUV）Sentry，针对阿维亚尔海山（Axial Seamount）开展了科考巡航。本次航次共在该海山及其周边区域完成7次AUV Sentry下潜作业。此处提供的Sentry导航数据以1Hz频率采样，采用类SCC格式的逗号分隔ASCII文本文件存储，并附带列标题。该导航数据在潜次结束后通过结合超短基线（Ultra-Short Baseline, USBL）声学导航与多普勒测速仪（Doppler Velocity Log, DVL）的观测信息完成重导航处理。本数据集为“阿维亚尔海山变形监测方法进阶（Advancing Deformation Monitoring Methods at Axial Seamount）”项目的采集与处理成果之一。本研究得到美国国家科学基金会（National Science Foundation, NSF）项目OCE17-36882、OCE17-36926及OCE17-37019资助。
