Temperature profiles from MBT casts from the MCCULLOCH from Ocean Weather Station D (OWS-D), E (OWS-E), and H (OWS-H) in the North Atlantic Ocean from 04 January 1969 to 03 February 1969 (NODC Accession 6900132)

Bathythermograph data were collected from the MCCULLOCH within a 1-mile radius of Ocean Weather Station D (4400N 04100W), E (3500N 04800W), H (3800N 07100W), and in transit. Data were collected by the United States Coast Guard from 04 January 1969 to 03 February 1969. 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 the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

本数据集包含麦卡洛克号（MCCULLOCH）于海洋气象站D（44°00′N 041°00′W）、E（35°00′N 048°00′W）、H（38°00′N 071°00′W）周边1英里范围内及航行途中采集的海水温深仪（Bathythermograph）数据。数据由美国海岸警卫队于1969年1月4日至1969年2月3日期间采集，该观测平台配备专业设备与操作人员，可开展气象与海洋环境观测。数据已由国家海洋数据中心（National Oceanographic Data Center, NODC）处理为符合NODC标准的通用海水温深仪输出格式（Universal Bathythermograph Output, UBT）。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。

UBT文件格式用于存储通过机械海水温深仪（Mechanical Bathythermograph, MBT）采集的温度-深度剖面数据。MBT观测的最大探测深度约为285米，因此MBT数据仅可用于研究海洋上层的热结构特征。每条观测记录均包含航次信息、观测日期、位置与时间，数据记录由温度-深度值对构成，本文件中的温度数据按均匀5米的深度间隔进行记录。
