Processed Underway Hydrographic and Weather and Ship-state Data (JGOFS) from the Antarctica Ross Sea acquired during R/V Nathaniel B. Palmer expedition NBP1502 (2015)

This data set was acquired with a Meteorological Sensor, Echosounder, Thermosalinograph, Navigation System and Fluorometer during R/V Nathaniel B. Palmer expedition NBP1502 conducted in 2015 (Chief Scientist: Dr. Philip Bart, Investigators: Dr. Philip Bart, Dr. John Anderson). These data files are of JGOFS (ASCII) format and include Bathymetry, Conductivity, Fluorescence, Infrared Radiation, Meteorological, Navigation, Salinity, Temperature and Visible Radiation data that were processed after acquisition. 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): Timing and Duration of the LGM and Post-LGM Grounding Events in Whales Deep Paleo Ice Stream, Eastern Ross Sea Middle Continental Shelf; Evidence for Paleo Ice Stream Collapse in the Western Ross Sea since the Last Glacial Maximum. Funding was provided by NSF award(s): PLR12-46353, PLR12-46357.

本数据集系2015年R/V Nathaniel B. Palmer考察队NBP1502航次中，利用气象传感器、回声测深仪、温盐计、导航系统和荧光计等设备所采集。考察队首席科学家为菲利普·巴特博士，调查员包括菲利普·巴特博士和约翰·安德森博士。数据文件采用JGOFS（ASCII）格式，包含地形测量、电导率、荧光、红外辐射、气象、导航、盐度、温度和可见辐射等多方面数据，均为采集后经过处理的数据。该数据集基于校准数据，以一分钟为间隔进行降采样生成。部分字段为从多个原始输入中派生出的测量值。数据采集作为以下项目的一部分：鲸深古冰流和末次冰期后固定事件的时间与持续期研究；以及罗氏海西部自末次冰期最大冰盛期以来的古冰流崩溃证据。项目资金由美国国家科学基金会（NSF）提供的奖项PLR12-46353和PLR12-46357资助。
