资源简介:
Bathythermograph data were collected from the TANEY within a 1-mile radius of Ocean Weather Station H (3800N 07100W) and in transit. Data were collected by the United States Coast Guard from 19 October 1974 to 08 November 1974. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instrument. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

海水温度深度记录仪(Bathythermograph)数据采集自"TANEY"号船只,采样范围覆盖海洋气象站H(38°00′N,71°00′W)周边1英里海域及航行途中区域。该数据由美国海岸警卫队于1974年10月19日至1974年11月8日期间采集。该观测船配备专业观测设备并配有操作人员,用于开展气象与海洋状况观测。所有数据均由国家海洋数据中心(NODC)处理为符合NODC标准的通用海水温度深度记录仪输出(Universal Bathythermograph Output, UBT)格式。完整的格式说明可从NODC官网的https://www.nodc.noaa.gov/General/NODC-Archive/bt.html 获取。 UBT文件格式用于存储通过投弃式海水温度深度剖面仪(expendable bathythermograph, XBT)获取的温度-深度剖面数据。标准型XBT可获取最大深度约450米或760米的温度剖面;若配备专用仪器,测量深度可达1830米。每条观测记录均包含航次信息、观测位置、日期与时间,数据记录由多组温度-深度数值对构成。与机械式海水温度深度记录仪(MBT)数据文件不同——后者以固定5米间隔记录温度数值,XBT数据文件中的温度数值对应的深度并不均匀。这些深度点为以可接受精度记录温度曲线所需的最少拐点数量。但在数据输出时,用户可选择获取拐点处的温度数值,或通过插值得到固定深度间隔下的温度数值。
