ABE AUV near-bottom merged navigation and raw magnetic sensor data, Kane Megamullion area, Mid-Atlantic Ridge (KN180-02, 2004)

This data set consists of raw magnetic field measurements and vehicle corrected navigation for autonomous underwater vehicle (AUV) ABE (Autonomous Benthic Explorer) dives over the Kane Megamullion located on the south side of the Kane transform and west flank of the Mid-Atlantic Ridge. The data were collected in 2004 during research cruise KN180-02 on R/V Knorr. AUV ABE was an experimental vehicle built by engineers at Woods Hole Oceanographic Institution (WHOI) and was eventually operated as part of National Deep Submergence Facility (NDSF) funded by the National Science Foundation (NSF). ABE was lost at sea in 2010. Magnetic data is supplied by a Develco model 3-axis fluxgate sensor mounted inside the hull of AUV ABE. Navigation is primarily by long-baseline (LBL) transponder and Doppler velocity log (DVL) where available. The magnetic data consists of raw magnetic values that have not been corrected (calibrated) for the magnetic effects of the AUV and have not been corrected for the IGRF. The data files are in ASCII format with the following columns: year, month, day, hour, min, sec, longitude(decimal degrees), latitude (decimal degrees), depth (meters), pressure (decibars), heading (degrees), pitch (degrees), roll (degrees), altitude (meters), mag02x (nT), mag02y (nT), mag02z (nT), optical backscatter sensor OBS (volts), redox potential eh (volts), rate of change of redox potential deh/dt (volts/second), oxygen O2 (micromolar), temperature (celsius), conductivity (siemens/meter), sound speed (meters/second), sound velocity profile SVP (meters/second). Where no sensor data are reported it is shown by 0.0. Navigation commenced only on the seafloor and is flagged with "NaN" where no navigation data is available. The data set was collected under grant OCE-0118445 from the US National Science Foundation.

本数据集包含自主水下航行器（Autonomous Underwater Vehicle, AUV）ABE（自主底栖探测器，Autonomous Benthic Explorer）在位于凯恩转换断层南侧、大西洋中脊西翼的凯恩巨型拆离岩体（Kane Megamullion）上方开展下潜作业时采集的原始磁场测量数据与经载体校正的导航数据。该数据采集于2004年，由克诺尔号（R/V Knorr）考察船执行的KN180-02科考航次完成。自主水下航行器ABE为伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）工程师研发的试验型水下航行器，后被纳入由美国国家科学基金会（National Science Foundation, NSF）资助的国家深潜设施（National Deep Submergence Facility, NDSF）运营，并于2010年在海上失联。磁场数据由安装在ABE船体内部的Develco型三轴磁通门传感器采集。导航数据主要依赖长基线（Long-Baseline, LBL）应答器与多普勒测速仪（Doppler Velocity Log, DVL，可用时）获取。本次提供的原始磁场数据未针对AUV自身的磁场效应进行校正，也未校正国际地磁参考场（International Geomagnetic Reference Field, IGRF）。数据文件采用ASCII格式，各列依次为：年、月、日、时、分、秒、经度（十进制度）、纬度（十进制度）、水深（米）、压力（分巴）、航向（度）、俯仰（度）、横滚（度）、高度（米）、mag02x（纳特斯拉，nT）、mag02y（纳特斯拉，nT）、mag02z（纳特斯拉，nT）、光学后向散射传感器（Optical Backscatter Sensor, OBS）电压、氧化还原电位eh（伏特）、氧化还原电位变化率deh/dt（伏特/秒）、氧气O2浓度（微摩尔）、温度（摄氏度）、电导率（西门子/米）、声速（米/秒）、声速剖面（Sound Velocity Profile, SVP，米/秒）。无对应传感器数据的字段以0.0填充。导航数据仅在航行器抵达海底后开始记录，无可用导航数据的位置标记为"NaN"。本数据集由美国国家科学基金会资助项目OCE-0118445采集完成。

背景与挑战

背景概述

该数据集包含2004年自主水下航行器ABE在中大西洋洋脊Kane Megamullion区域采集的原始磁场测量数据和车辆校正导航数据，数据来自研究巡航KN180-02，由伍兹霍尔海洋研究所建造的ABE收集，文件为ASCII格式，包含时间、位置、深度、姿态、磁场分量等多列参数，数据未进行磁校正和IGRF校正，受美国国家科学基金会资助。数据集具有历史价值，因为ABE航行器已于2010年失事。
