Temperature profiles from MBT casts from the MELLON from Ocean Weather Station V (OWS-V) in the North Pacific Ocean from 30 September 1968 to 26 October 1968 (NODC Accession 6800131)

Bathythermograph data were collected from the MELLON within a 1-mile radius of Ocean Weather Station V (3400N 16400E) and in transit. Data were collected by the United States Coast Guard from 30 September 1968 to 26 October 1968. 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.本数据集为海水温度深度记录仪（Bathythermograph，BT）采集数据，采集平台为“MELLON”号，覆盖范围涵盖海洋气象站V（34°00′N，164°00′E）周边1英里海域及航行途中区域。数据由美国海岸警卫队于1968年9月30日至1968年10月26日期间完成采集。该平台配备专业观测设备与人员，用于开展气象与海洋状况监测。所有数据已由国家海洋数据中心（NODC）处理为NODC标准通用海水温度深度记录仪输出（Universal Bathythermograph Output，UBT）格式。完整格式说明可通过NODC官网获取：www.nodc.noaa.gov/General/NODC-Archive/bt.html。 UBT文件格式用于存储机械式海水温度深度记录仪（mechanical bathythermograph，MBT）获取的温度-深度剖面数据。MBT观测的最大探测深度约为285米，因此该类数据仅可用于研究海洋上层水体的热结构特征。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以5米的等深度间隔进行存储。
