Oceanographic station data from bottle casts from the TANEY from Ocean Weather Station V (OWS-V) in the North Pacific Ocean 28 March 1971 to 28 May 1971 (NODC Accession 7101387)

Oceanographic station data were collected from the TANEY within a 1-mile radius of Ocean Weather Station V (3400N 16400E) and in transit. Data were collected by the United States Coast Guard (USCG) from 28 March 1971 to 28 May 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.

本数据集的海洋站数据采集自TANEY号作业船只，覆盖范围包括海洋气象站V（34°00′N，164°00′E）周边1英里范围内及航行途中。数据采集工作由美国海岸警卫队（United States Coast Guard, USCG）于1971年3月28日至1971年5月28日期间完成。国家海洋数据中心（National Oceanographic Data Center, NODC）已将所有数据处理为NODC标准站数据II输出格式（Station Data II Output Format, SD2）。完整的格式说明可通过NODC官方网址https://www.nodc.noaa.gov/General/NODC-Archive/sd2.html查阅。

SD2格式存储了离散深度层上记录的物理化学海洋学数据。大部分观测采用多瓶式南森（Nansen）采水器下放采集或其他类型的水体采样装置完成，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数据上报至NODC时采用了与南森采水器采样一致的深度分层标准，因此其处理与存储流程与南森采水器数据完全一致。每个观测站点均附带航行相关信息（如作业船只、所属国家、所属机构）、站位坐标、观测日期与时间等内容。核心观测参数以温度与盐度为主，但同时也会记录溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐以及pH值等指标。采样时的气象条件（如气温、气压、风速、海浪情况）以及辅助观测数据（如水色（弗洛尔-乌勒（Forel-Ule）色标）、水体透明度（塞氏盘深度）、海底水深）也可能被一并记录。密度（sigma-t）、声速以及动态深度异常值可通过实测参数计算得到。每个站点的数据既包含实测深度层上的原始观测值，也包含经插值得到的标准深度层数据值。
