Temperature profiles from XBT and MBT casts from the NOAA ship Researcher as part of the International Decade of Ocean Exploration / Cooperative Investigations of the Caribbean and Adjacent Regions (IDOE/CICAR) from 14 July 1971 to 01 September 1971 (NODC Accession 7101414)

Temperature profiles were collected from XBT and MBT casts from the NOAA ship Researcher from 14 July 1971 to 01 September 1971. Data were collected by the Atlantic Oceanographic and Meteorological Laboratory (AOML) as part of the International Decade of Ocean Exploration / Cooperative Investigations of the Caribbean and Adjacent Regions (IDOE/CICAR). 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 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data records are comprised of pairs of temperature-depth values. The XBT data files contain temperature values at non-uniform depths. These depths were recorded at the minimum number of points (''''inflection points'''') required to accurately define the temperature curve.
Standard XBTs can obtain profiles to depths of 450 m or 760 m. Special instruments permit measurements to 1830 m.

1971年7月14日至1971年9月1日期间，采集自美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）“Researcher”号科考船开展的投弃式温深仪（expendable bathythermograph, XBT）与机械式温深仪（mechanical bathythermograph, MBT）观测剖面的温度剖面数据。该数据由大西洋海洋与气象学实验室（Atlantic Oceanographic and Meteorological Laboratory, AOML）作为国际海洋勘探十年/加勒比海及邻近区域合作调查（International Decade of Ocean Exploration / Cooperative Investigations of the Caribbean and Adjacent Regions, IDOE/CICAR）项目的一部分完成采集。美国国家海洋数据中心（National Oceanographic Data Center, NODC）将数据处理为符合其标准的通用温深仪输出格式（Universal Bathythermograph Output, UBT）。完整的格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。

UBT格式包含通过投弃式温深仪（XBT）获取的温度-深度剖面数据。每次观测均记录了航次信息、站位坐标、日期与时间。数据记录由成对的温度-深度数值构成。XBT数据文件中的温度值对应非均匀分布的深度，这些深度仅在能够精准刻画温度曲线所需的最少测点（即“拐点”）处被记录。

常规投弃式温深仪可获取深度达450米或760米的温度剖面，特殊定制仪器可实现1830米水深的测量。
