Temperature profile and other data collected using bottle casts in the North Atlantic Ocean from NOAA Ship RESEARCHER from 30 March 1977 to 14 April 1977 (NODC Accession 7700856)

Temperature profile, sound velocity, and chemical data were collected using bottle casts from the NOAA Ship RESEARCHER in the North Atlantic Ocean from 30 March 1977 to 14 April 1977. Data were collected and submitted by Woods Hole Oceanographic Institute (WHOI). Data were processed by NODC to the NODC standard Oceanographic Station Data (SD2) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/sd2.html. The SD2 format is used for physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi- bottle Nansen casts or other types of water samplers. A small amount (about 5%) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information, position, date and time are reported for each station. Each station contains the measurements taken at observed depth levels, but also includes data values interpolated to a set of standard depth levels.本数据集采集了1977年3月30日至1977年4月14日期间，于北大西洋海域由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）"研究号"科考船通过瓶式采水器采样获取的温度剖面、声速及化学数据。数据由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institute, WHOI）采集并提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）将数据处理为NODC标准海洋站数据（Oceanographic Station Data, SD2）格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/sd2.html获取。 SD2格式用于存储离散深度层级下记录的物理-化学海洋学数据。多数观测采用多瓶南森采水器（multi-bottle Nansen casts）或其他类型的水体采样器完成，约5%的少量数据则通过电子CTD（电导率-温度-深度, conductivity-temperature-depth, CTD）或STD（盐度-温度-深度, salinity-temperature-depth, STD）记录仪获取。不过，CTD/STD数据提交时的深度层级与南森采水器采样数据一致，因此其处理与存储流程与南森数据完全相同。每个测站均附带航次信息、站位坐标、观测日期与时间。每个测站既包含实测深度层级下的测量数据，也包含经插值得到的标准深度层级数据集。
