Oceanographic station data from bottle casts from the INGHAM from Ocean Weather Station E (OWS-E) and H (OWS-H) in the North Atlantic Ocean 29 January 1971 to 11 February 1971 (NODC Accession 7100877)

Oceanographic station data were collected from the INGHAM within a 1-mile radius of Ocean Weather Station E (3500N 04800W), H (3800N 07100W), and in transit. Data were collected by the United States Coast Guard (USCG) from 29 January 1971 to 11 February 1971. 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.

本数据集为海洋站观测数据，采集自英厄姆（INGHAM）号科考船，覆盖海洋气象站E（35°00′N，48°00′W）、H（38°00′N，71°00′W）周边1英里海域及航行途中。数据由美国海岸警卫队（USCG）于1971年1月29日至1971年2月11日采集，后续由美国国家海洋数据中心（NODC）按照其标准站数据II输出格式（SD2）完成标准化处理。完整格式说明可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/sd2.html查阅。

SD2格式存储了离散深度层级下的物理化学海洋学观测数据。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）或STD（盐度-温度-深度，salinity-temperature-depth）记录仪获取。尽管CTD/STD数据上报至NODC时的深度层级与南森采水数据保持一致，但其处理与存储流程与南森采水数据完全相同。每个测站均附带航行信息（如船舶、所属国家/机构）、位置、日期与时间。核心观测参数以温度与盐度为主，同时可上报溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值等指标。采水作业时的气象条件（如气温、气压、风向、风速、海浪状况）也可被记录，此外还包含水体颜色（福勒-于勒色标，Forel-Ule scale）、水体透明度（赛克盘深度，Secchi disk depth）及海底深度等辅助数据。密度（sigma-t）、声速及动态深度异常等参数则通过实测指标计算得到。每个测站既包含实测深度层级下的原始观测数据，同时也包含插值至标准深度层级的衍生数据集。
