Temperature profiles from MBT casts from the GRESHAM from Ocean Weather Station N (OWS-N) in the North Pacific Ocean from 05 July 1963 to 16 July 1963 (NODC Accession 6300127)

Bathythermograph data were collected from the GRESHAM within a 1-mile radius of Ocean Weather Station N (3000N 14000W) and in transit. Data were collected by the United States Coast Guard from 05 July 1963 to 16 July 1963. 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.本数据集为温深计（bathythermograph）观测数据，采集自格雷沙姆号（GRESHAM），采集范围覆盖N号海洋气象站（30°N 140°W）周边1英里海域及航行途中。数据由美国海岸警卫队于1963年7月5日至1963年7月16日收集。该观测平台配备专业设备并配有操作人员，用于开展气象与海洋状况观测。数据由美国国家海洋数据中心（National Oceanographic and 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文件格式用于存储通过机械温深计（mechanical bathythermograph, MBT）获取的温度-深度剖面数据。机械温深计观测的最大深度约为285米，因此其数据仅适用于研究海洋上层的热结构。每条观测记录均包含航次信息、观测日期、位置与时间。数据记录由多组温度-深度值对组成，文件内的温度数据以5米为固定深度间隔进行记录。
