Oceanographic station data from bottle casts from the BIBB and other platforms from multiple Ocean Weather Station (OWS) in the North Atlantic Ocean and North Pacific Ocean 13 April 1968 to 11 July 1969 (NODC Accession 6900853)

Oceanographic station data were collected from the BIBB, GRESHAM, and HUMBOLDT within a 1-mile radius of Ocean Weather Station D (4400N 04100W), E (3500N 04800W), H (3800N 07100W), V (3400N 16400E), and in transit. Data were collected by the United States Coast Guard (USCG) from 13 April 1969 to 11 July 1969. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2). Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/sd2.html. The SD2 format contains 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 percent) 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 (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity , but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.本数据集的海洋站观测数据采集自“比布”号（BIBB）、“格雷沙姆”号（GRESHAM）与“洪堡”号（HUMBOLDT）的作业区域，覆盖海洋气象站D（44°00′N，041°00′W）、E（35°00′N，048°00′W）、H（38°00′N，071°00′W）、V（34°00′N，164°00′E）周边1英里范围，同时包含航行途中采集的数据。所有观测数据由美国海岸警卫队（United States Coast Guard, USCG）于1969年4月13日至1969年7月11日期间完成采集。数据已由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准站数据II输出格式（Station Data II Output Format, SD2）。完整格式说明可通过NODC官方网址https://www.nodc.noaa.gov/General/NODC-Archive/sd2.html获取。 SD2格式存储了离散深度层采集的物理海洋与化学海洋观测数据。绝大多数观测采用多瓶式南森采水器（multi-bottle Nansen casts）或其他类型水体采样器完成，仅约5%的观测数据通过电子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数据均按照与南森采水数据一致的深度层级上报至NODC，且处理与存储流程与南森采水数据完全一致。每个观测站均附带航次信息（如作业船舶、所属国家、研究机构）、观测位置、日期与时间。核心观测参数以温度与盐度为主，同时可报告溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值。采水作业时的气象条件（如气温、气压、风速、浪况）同样可被记录，此外还包含辅助观测数据，如水体颜色（福勒-尤勒色度标，Forel-Ule scale）、水体透明度（塞氏盘深度，Secchi disk depth）及海底深度。密度（σ-t，sigma-t）、声速及动力深度异常等参数可通过实测数据计算得到。每个观测站既包含实测深度层的原始观测数据，同时也包含插值至标准深度层级的数据集。
