Underway Hydrographic, Weather and Ship-state Data (JGOFS) from the Drake Passage acquired during the Laurence M. Gould expedition LMG1411 (2014)

This data set was acquired with a ship-based Meteorological Sensor, Fluorometer, Thermosalinograph, Echosounder Sonar, and Navigation system during Laurence M. Gould expedition LMG1411 conducted in 2014 (Chief Scientist: Dr. Andrew Thompson). These data files are of JGOFS (ASCII) format and include Temperature, Meteorological, Conductivity, Infrared Radiation, Fluorescence, Visible Radiation, Salinity, Bathymetry, and Navigation data and were processed after data collection. This data set was created from calibrated data decimated at 1-minute intervals. Several fields are derived measurements from more than a single raw input. Data were acquired as part of the project(s): Continuously monitor the fronts in the southern Drake Passage by deploying and piloting a pair of ocean gliders to collect approx. 1000 profiles of temp, salinity, dissolved oxygen, fluorescence and optial backscatter.

本数据集采集自2014年执行的Laurence M. Gould号科考航次LMG1411（首席科学家：Andrew Thompson博士），搭载的观测系统包括船载气象传感器、荧光计（Fluorometer）、温盐计（Thermosalinograph）、回声测深声呐（Echosounder Sonar）以及导航系统。本次数据文件采用JGOFS（ASCII）格式，涵盖温度、气象、电导率、红外辐射、荧光、可见光辐射、盐度、水深（Bathymetry）以及导航数据，所有数据均在采集完成后进行了预处理。本数据集基于经校准后的原始数据以1分钟为间隔抽稀生成，其中多个字段为基于多组原始输入衍生的测量值。本次数据采集隶属于下述研究项目：通过部署并操控一对海洋滑翔机，持续监测南德雷克海峡的锋面结构，以获取约1000条温度、盐度、溶解氧、荧光以及光学后向散射的剖面数据。
