TN250 DAS/IMET Data [Shull/UW]

This dataset includes data from the DAS/IMET system onboard the UNOLS R/V Thompson ship during the BEST 2010 TN250 (summer) cruise. The DAS system collects data at an operator selected interval; this is typically set at one sample (saved) per minute. The data collected are from the IMET sensors, SBE-21 Themosalinograph, Bathy-2000 and Winch systems. The data are time, date and position tagged. A new data file is started each GMT day at 00:00 and ends at 23:59 (depending on the data storage interval). The numerous data files have been collected into tar files with one tar file for each data type. The data types are configuration files, raw data files, and plot files. The data files are named TN250DAS.190 with the three digit extension representing the Julian date. Each line is a comma-separated string of data values. The order of the data values is described in the DAS CFG files, named TN250DAS.CFG included with the data files.本数据集涵盖2010年BEST航次TN250（夏季航次）期间，搭载于UNOLS研究船R/V Thompson的DAS/IMET系统所采集的科考数据。该DAS系统支持操作人员自定义采集间隔，常规设置为每分钟采集并保存1个样本。本次采集的数据覆盖IMET传感器、SBE-21型温盐记录仪（Themosalinograph）、Bathy-2000型测深仪以及绞车系统。所有数据均附带时间、日期及地理位置标签。每个格林尼治标准时间（GMT）日的00:00将生成一个新的数据文件，并于当日23:59终止，具体终止时间取决于数据存储间隔。海量零散数据文件已按数据类型打包为tar压缩包，每种数据类型对应一个专属tar文件。数据类型涵盖配置文件、原始数据文件与绘图文件三类。数据文件的命名格式为TN250DAS.xxx，其中三位扩展名代表儒略日（Julian date）。数据文件的每一行均为以逗号分隔的数据值字符串。数据值的排列顺序可在随数据文件一同提供的DAS配置文件中查阅，该配置文件的命名为TN250DAS.CFG。
