Oceanographic station data from bottle casts from the KLAMATH from Ocean Weather Station V (OWS-V) in the North Pacific Ocean from 02 August 1971 to 30 September 1971 (NODC Accession 7200662)

Oceanographic station data were collected from the KLAMATH within a 1-mile radius of Ocean Weather Station V (3400N 1640E) and in transit. Data were collected by the United States Coast Guard (USCG) from 02 August 1971 to 30 September 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.海洋站数据采集自克拉马斯号（KLAMATH），采集范围覆盖海洋气象站V（34°00′N，164°00′E）周边1英里海域及航行途中。本次数据由美国海岸警卫队（United States Coast Guard, USCG）于1971年8月2日至1971年9月30日期间采集。数据由国家海洋数据中心（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）。完整的格式说明可通过NODC官网的https://www.nodc.noaa.gov/General/NODC-Archive/sd2.html获取。 SD2格式包含离散深度层级下记录的物理-化学海洋学数据。多数观测通过多瓶南森采水剖面（multi-bottle Nansen casts）或其他类型的水体采样器完成。少量（约占总数据的5%）数据通过电子电导率-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数据以与南森采水数据一致的深度层级上报至NODC，并与南森数据采用相同流程进行处理与存储。每个站点均记录有航次信息（如船舶、所属国家/机构）、站位坐标、日期与时间。核心观测参数为温度与盐度，此外还可记录溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值等参数。采水作业时的气象条件（如气温、气压、风向风速、浪况）亦可被记录，辅助数据则包括水体颜色（福勒-于勒色度标度，Forel-Ule scale）、水体透明度（塞氏盘深度，Secchi disk depth）及海底水深。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。每个站点既包含观测深度层级下的实测数据，同时也包含插值至标准深度层级后的数据集。
