Oceanographic station data from bottle casts from the TANEY from Ocean Weather Station H (OWS-H) in the North Atlantic Ocean from 20 September 1975 to 30 September 1975 (NODC Accession 7600086)

Oceanographic station data were collected from the TANEY within a 1-mile radius of Ocean Weather Station H (3800N 07100W) and in transit. Data were collected by the United States Coast Guard (USCG) from 20 September 1975 to 30 September 1975. 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.

海洋观测站数据采集自坦尼号（TANEY）考察船，采集范围覆盖海洋气象站H（38°00′N，71°00′W）周边1英里范围内及航行途中。数据由美国海岸警卫队（United States Coast Guard, USCG）于1975年9月20日至1975年9月30日期间采集完成。数据经国家海洋数据中心（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）。完整格式说明可从NODC获取，网址为www.nodc.noaa.gov/General/NODC-Archive/sd2.html。

SD2格式包含离散深度层级下记录的物理化学海洋学数据。绝大多数观测采用多瓶南森采水剖面（multi-bottle Nansen casts）或其他类型水体采样器完成。少量数据（约占总数据量的5%）通过电子电导率-温度-深度（conductivity-temperature-depth, CTD）记录仪或盐度-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剖面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。核心观测参数为温度与盐度，此外还可报告溶解氧、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、风向、海浪）亦可被记录，同时还可附带辅助数据，例如水色（弗洛尔-于勒比色卡，Forel-Ule scale）、水体透明度（塞氏盘深度，Secchi disk depth）及海底深度。密度（sigma-t）、声速及动态深度异常值可通过实测参数计算得到。每个观测站既包含实测深度层级下的原始观测数据，也包含插值至标准深度层级后的标准化数据集。
