Temperature profiles from XBT casts from the TANEY from Ocean Weather Station H (OWS-H) in the North Atlantic Ocean from 13 September 1975 to 03 October 1975 (NODC Accession 7500970)

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 13 September 1975 to 03 October 1975. 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.本数据集的温深计（Bathythermograph）数据采集自TANEY号平台，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的观测区域。数据由美国海岸警卫队于1975年9月13日至1975年10月3日期间采集。该平台配备了天气与海况观测系统并配有专职操作人员。数据已由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准通用温深计输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可从NODC官网获取，网址为www.nodc.noaa.gov/General/NODC-Archive/bt.html。 UBT文件格式用于存储通过一次投入式温深计（expendable bathythermograph, XBT）获取的温度-深度剖面数据。标准XBT可实现约450米或760米的探测深度，搭配专用仪器时，最大探测深度可达1830米。每条观测记录均包含巡航信息、观测位置、观测日期与时间。数据记录由多组温度-深度值对组成。与机械温深计（Mechanical Bathythermograph, MBT）数据文件以均匀5米间隔记录温度值不同，XBT数据文件的温度采样对应的深度并不均匀，其采样点为以可接受精度完整记录温度曲线所需的最少拐点数量。不过在数据输出环节，用户可选择获取拐点处的原始温度值，或通过插值得到均匀深度间隔下的温度值。
