Underway Hydrographic, Weather and Ship-state Data (JGOFS) from Laurence M. Gould expedition LMG0401 (2004)

This data set was acquired with a ship-based Knudsen 320BR Echosounder Sonar, Navigation system, Meteorological Sensor, Fluorometer, and Thermosalinograph during Laurence M. Gould expedition LMG0401 conducted in 2004 (Chief Scientist: Dr. William Fraser). These data files are of JGOFS format and include Meteorological, Conductivity, Bathymetry, Infrared Radiation, Fluorescence, Navigation, Temperature, Visible Radiation, and Salinity data. 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): Long-Term Ecological Research on the Antarctic Marine Ecosystem: An Ice-Dominated Environment (LTER).

本数据集于2004年，由首席科学家威廉·弗拉塞博士领导的劳伦斯·M·古尔德号（LMG0401）考察活动中，利用基于船舶的Knudsen 320BR回声测深仪、导航系统、气象传感器、叶绿素荧光仪及海水盐度计等设备采集而成。数据文件采用JGOFS格式，包含气象、电导率、水深、红外辐射、荧光、导航、温度、可见辐射及盐度等数据。该数据集基于每分钟一次的校准数据进行降采样生成。多个字段为从多个原始输入中派生出的测量值。数据收集作为长期生态学研究项目的一部分，即针对以冰层为主导的南极海洋生态系统的长期生态学研究（LTER）。
