2017 AUV Sentry vehicle-corrected navigation and raw magnetic sensor data, Axial Seamount

This data set consists of raw magnetic field measurements and vehicle-corrected navigation for autonomous underwater vehicle (AUV) Sentry dives over Axial Seamount, Juan de Fuca Ridge collected in 2017 during research cruise RR1712 on R/V Roger Revelle. AUV Sentry is operated as part of National Deep Submergence Facility (NDSF) by Woods Hole Oceanographic Institution (WHOI) and is funded by the National Science Foundation (NSF). The AUV Sentry magnetometer is an APS (Applied Physics Systems) model 1540 3-axis fluxgate sensor (https://www.appliedphysics.com/products/magnetometers/). AUV Sentry has three magnetometer sensors, two are located mid-body on the port and starboard side and one is located in the top of the vehicle. These data files contain raw magnetic field data from the 'top' sensor which is also identified as the '02' sensor. Navigation is by USBL. The data files are in ASCII format with the following columns: year, month, day, hour, min, sec, latitude (dec. degrees), longitude (dec. degrees), depth (meters), pressure (decibars), heading (degrees), altitude (meters), mag02x (nT), mag02y (nT), mag02z (nT), optical backscatter sensor OBS (volts), redox potential eh (volts), rate of change of redox potential dehdt (volts/second), oxygen O2 (micromolar), temperature (celsius), conductivity (siemens/meter), sound speed (meters/second), sound velocity profile SVP (meters/second), oxygen reduction potential (volts). The data set was collected under grant OCE17-36882 from the National Science Foundation. The AUV Sentry magnetic data were analyzed and interpreted under a Woods Hole Oceanographic Institution (WHOI) internal research grant to Maurice Tivey and with additional support for Bailey Fluegel by the WHOI Summer Student Fellow program in 2021. The data set is described in Fluegel et al., GRL, 2022.

本数据集包含了2017年RR1712科研巡航期间，于罗杰·雷维尔号（R/V Roger Revelle）上对亚克斯火山（Axial Seamount）和胡安·德富卡脊（Juan de Fuca Ridge）进行的自主水下航行器（AUV）Sentry潜水采集的原始磁场测量值和车辆校正的导航数据。AUV Sentry由伍兹霍尔海洋研究所（WHOI）在国家深海潜水设施（NDSF）的运营下运行，并由美国国家科学基金会（NSF）资助。Sentry磁力仪为应用物理系统公司（APS）生产的1540型三轴霍尔效应传感器（https://www.appliedphysics.com/products/magnetometers/）。AUV Sentry配备有三个磁力仪传感器，其中两个位于船体中部左右两侧，另一个位于车顶。这些数据文件包含来自'顶部'传感器（亦称为'02'传感器）的原始磁场数据。导航采用单波束测深法（USBL）。数据文件为ASCII格式，包含以下列：年份、月份、日期、小时、分钟、秒、纬度（十进制度）、经度（十进制度）、深度（米）、压力（分贝）、航向（度）、海拔（米）、磁力02x（纳特）、磁力02y（纳特）、磁力02z（纳特）、光学后向散射传感器OBS（伏特）、氧化还原电位eh（伏特）、氧化还原电位变化率dehdt（伏特/秒）、氧气O2（微摩尔）、温度（摄氏度）、电导率（西门子/米）、声速（米/秒）、声速剖面SVP（米/秒）、氧化还原电位（伏特）。数据集的收集得到了国家科学基金会（NSF）的OCE17-36882项目资助。AUV Sentry的磁力数据在伍兹霍尔海洋研究所（WHOI）内部研究资助下由莫里斯·蒂维（Maurice Tivey）进行分析和解释，并在2021年得到了WHOI夏季学生研究员项目的额外支持。该数据集在Fluegel等人撰写的《地球物理研究快报》（GRL）2022年的论文中进行了描述。
